Car lost power and I had to coast to a gas station. The car won’t start . I just hear a click what sounds it could be the starter. Any ideas or suggestions on this P305400 code as I think it’s not allowing my car to start. I also had misfire codes but have had a tune up done today. After that the car started for a few seconds then cut off. I’m at a hole in the road as to what’s going on since the the P305400 Code. Please Please Help! Thanks.

Great video sirs...very informative! I just traded my A6 3.0T for a low-miles (29K) A8 3.0T a few months ago. I'd initially sought an A8 4.0T, or S8, but those cars were $15-40K more, just to get the larger engine. After owning the A6 for a while, I loved its 3.0T engine, and found it sufficiently strong in the A8, which is only 300 lbs heavier than the A6. Plus, my A8 gets 30mpg on the freeway! I plan on keeping this A8 forever, so I'm glad to read comments here that the engine is reliable long-term. So happy with Audi engineering! Subscribed!!

Go with an 8.5 if you want an S-tronic. The b8 gen has known issues with the DL501 transmission that can become costly if not sorted, especially if you are from NA. In Europe they are cheaper to fix. On the 8.5 facelift all the issues with it were fixed tough so worth the extra money over the 8.
I have had a 2012 Q7 3.0t for 4 years and just this year had to change the brake pads. 172,000 miles. Oil changes every 5,000. And don't run the wrong oil in these, the oil consumption goes way up...lol It was using about a quart of oil between oil changes and progressed to almost 2 quarts between oil changes then I got the high pitch whistle that went away if I removed the oil filler cap. I should've known, but these are new to me. It was the PCV valve. When tearing it down, the black plastic pipe over the passenger side of the Pcv valve end crumbled off during removal. I barely touched the coolant nipple on the front coolant crossover pipe and it snapped off. And while the supercharger was off I found the source of my small oil leak that I had thought was the rear main seal. It was the oil filter housing instead and it leaks right between the engine & trans. The gasket was flat. I'm a 20+ year ASE tech so it's not difficult but this is what I found.

The rattle is very similar but obviously comes from the bottom of the car. Mechanics will try to get you to change the cats. Its probably not those....check the flex pipes first

Great video man. Super concise and detailed in useful ways to know what to pay attention to. I'm at 115k miles with mine and still enjoy the motor a lot.
I own a 2015 S4 and at 55k, I started to get the dreaded tensioner rattle. I replaced them in the winter months with the upgraded unit. These would be easy to replace if you owned the 3.2 v6 but since the 3.0T has the secondary valves on the back off the heads and the catalysts are right next to them, you’ll have to drop the engine down enough to be able to remove the cats so you can remove the bolts from the valves so you can finish removing the back cover to the tensioners. Yes! You will need special tools like the piston stop and a few hand tools to remove and tighten the bolts of the cam gears. A big help was removing the false fire wall which opened up the whole rear of the engine. Good luck if you’re attempting this job but you can do it if you take your time and check your work.

I have a B8 S4 and can attest to the robustness of the 3.0T. I think Audi knocked it out of the park with this engine. These make enough power to run 12.9's with the right tires and launch all day long. Put a Stage 1 tune, intake system, and S/C pulley and be deep into the 12's and not worry too much about breaking the engine. The transmissions are another story though. It's hit or miss with those. If you have an early DSG, you might want to keep a spare on hand to change out preferably from a later model. Just putting this out there for those who don't know, a new one is 14K from Audi. Yes, that is fourteen thousand dollars.
@@SuperEman500 B7 had the 4.2 v8, B8 has the 3.0t, b8.5 is the 2012 facelift of the B8 also with the 3.0t. You might be getting confused with the s5 which retained the V8 for a while after the 3.0t came out.
Excellent and precise content! I have this motor in the A6 and no headaches except the pcv valve replaced and 2 seconds chain rattle in the morning on cold starts. Such a great engine and very easily tunable to upwards of 400 hp. Thanks!
The lay out of everything is so great! Ty very much. the confidence I have now to buy a car with this engine is great,you were so clear and detailed, ty again .awesome! You might be do for a raise buddy ,lol
My '12 S4 had a recall on the thermostat several years ago, so I had the dealer replace it free of charge. So far, no issues and I still have the "garage princess" which is dressed in Stage 2+ APR, Vossen Wheels, Enlaes rear splitter, APR Big Brake kit, lowering springs, sway bars an Armytrix exhaust which is bananas. It's been a solid car!
Just bought a Q5 3.0 and this video puts me at ease for choosing this model over the 2.0T! Very informative! Can't wait for more DIYs on this fantastic and fun engine! Keep up the great videos 👍👍
Thank you for these videos, they are absolutely great, for someone looking to own a B8.5 soon, they are super super helpful, and the production quality is top notch. Look forward to more :)
Great video! I'm a staunch BMW guy but really like this motor as it seemingly has no show-stopper issues. At a glance this is a lot more solid than an N54/55 that have a litany of things to fret about...
Yeah just picked up a Q7 instead of the X5 bc there are just too many common n54/n55 engine issues that all cost 2k+ or an entire weekend of wrenching in your driveway.
@scott8934 well bmw and audi are pretty similar being both luxury brands from Germany. I tend to like the user setup of BMW but audi's can be more reliable. I've only owned my audi for 2 years so we shall see
I purchase all my parts for my 16 A6 3.0T from you guys! FCP Euro rocks! nobody comes close to your prices! He is completely correct the 3.0T is highly tuneable, got APR stage 2 tune with supercharger pulley upgrade put on a week ago and from fast to stupid fast!
I appreciated the review of the 3.0t. I bought a 2014 A8 (two years ago) and it has performed well. You very accurately explained the initial "rattle" that I hear upon start up and while it goes away in the prescribed time., I may get this looked at just to be on the safe side. Water pump and thermostat will also be serviced as well. With the supercharger off, I may have that serviced along with the PCV replacement since the labor will already have those components off the engine. Great video - glad I came across this and subscribed.
I'm in the process of buying a B8 S5 in the next week or so and being someone who hasn't owned an Audi before(I'm an Alfisti BTW) I was afraid of the unknown but this really gave me an idea of what to look out for. Thank you and keep it up!❤😊
The secondary air injection pump or SAI pump reduces the carbon emissions from a vehicle’s exhaust. The car's air injection pump also helps increase the catalytic converter's efficiency. Suppose your vehicle has a bad secondary air pump. In that case, hydrocarbon fumes will come out in an excessive amount from the exhaust., not to mention the pollution added to the environment.
You Should have mentioned the silicone gasket on the timing chain cover in the back of the engine. Very prone to leak since it is a silicone gasket right above the hot exhaust manifold. It’s an even more fun job if you strip the small torx screws, speaking from experience they stripped with barely any pressure by hand.
Incredibly informative and helpful, subscribed immediately after watching this. Shopping for a 2015 A6 3.0T and I'm a little concerned about the timing chain rattle issue. Some say it's not an issue, some say it can get worse over time as the age and the mileage of the car goes up. Is that something to be concerned about? Driving a 3.2l FSI at the moment, would love to see a video like this for that engine as well.
I hade an Audi A6 from 2005 with the 3.2 fsi engine. Mine wife goes to shop and comes back and the car wouldn't start anymore. Went to Audi, repair would cost €8400 they said ! Distribution/ chain problem. It happened arround 255 k kilometers, I don't know how much that is in miles. Bud for me, no 3.2 fsi engine again !
My cousin recently pyrchased a 2012 3.0T in an S5 cabriolet. (Midlife crisis mobile) Had it a few months but had only driven it on nice weekend afternoons. Stated that it had started to indicate low coolant. Unsure how hot it had run. He had added coolant 'a few times'. Had coolant pooling all over beneath supercharger. Front of engine had obviously had coolant leaking down it for a while. Water pump spun exceptionally freely, had issue with coolant pipe at thermostat housing, and passenger side 'window' of pcv valve/ oil separator was discolored. Just had a couple of pulleys, tensioner, belts, water pump, thermostat, pcv valve/ oil separator, several all hoses, the front coolant crossover pipe, the coolant pipe from the rear of the thermostat to the rear of the engine, and the pcv lines from the valve to the valve covers changed. Engine surged between 800 and 1200 rpm at idle. He states that it runs great under load. Has a P0068 and also a MAF/MAP code. Has a sound like a vacuum leak at rear of head on passenger side of engine. Throttle body and plate, as well as manifold cleaned as far as could be reached. 5 vacuum branch lines checked and are all intact to respective devices. Shop owner is stumped. Cousin and I have found several articles/ threads with this problem not being identified after substantial repairs made. ** Pcv valve was O6E black, and was replaced with O6E. Have heard of issues with alternate pcv valve, cracked intake, and a possible egr valve issue. Starts right up and runs smooth for 10 or 15 seconds, then starts surging. Thanks in advance for any thoughts.
That was very helpful because I’m looking at getting a 2014 Audi s4 with 77,000 kilometres on it so when I get it I’ll do a health check on the engine and see if everything is good and look at all the service records
Just put a deposit down on a 15 Q7 S-line with 107k on it. I plan on getting the JHM ecu and tcu tune right off the bat. I may just do some preventative maintenance on some of these items as well so I can have some piece of mind. Great info here
My local audi garage claim they need to take the engine out to change the chain tensioners. Needless to say that is expensive. Are you sure it can be done without taking the engine out
Oil filter housing gasket, oil cooler gasket and rear timing covers themselves (on the earlier motors, seems to be better on the newer ones) are a couple more common oil leaks
Just picked up a 2010 A6 for super cheap this weekend, from the ticking sound it's making it sounds like it'll need the timing chain tensioners, would like an in car diy on that
Id like to add to the PCV valve section, that it can cause some massive coolant leaks that you have no visible indications of besides coolant and oil mixture. The gaskets actually failed on my as well and was spewing some coolant into the open bay area around the PCV. So for anyone watching, it took me a bit to find this on some forums but there is information out there on it.
Don't forget the oil filter housing seal ( S4, S5 Supercharged engine). I replaced mine at 75,000. 2011 S4. Also replaced PCV valve, crossover pipe from the back of thermostat to firewall, water pump, and thermostat. Big job and long hours.
Very comprehensive video 👍 thank you very much, Im now the second owner of a B8 S4 and its also my first Audi. There's a lot to learn but this definitely lays a nice ground work for what to watch out for. Been working on cars my whole life but never anything like this, absolutely loving the car
The timing chain tensioner TSB should apply to all 3.0T cars... My '15 S4 rattles for about half a second on startup but has become more consistent on cold startups over time. I try to ignore it but it just sounds so bad haha. Still love the car though!
Most of it is the same. Thermostat, water pump, engine mounts (funny enough I've already replaced all of those on my rs5) as well as you'll need constant carbon cleans, camshaft positioning sensor goes bad, and timing chain tensioner have a similar issue as in the 3.0T as described. Sparks and coils are also the same as in this vid
@@mattw4211 Thanks. Good to know most of the common issues are easy to fix. I just picked up a 2015 a couple weeks ago with 37k km on it. I've read a couple forums talking about transmission failures which are probably my biggest concern at this point.
@@mattw4211 if you don’t mind me asking how much total for costs ? Been really thinking in pulling the trigger or just get a more care free TL SHAWD. Just not as of a looker as the s4
Great video and very informative. I've a 2014 ( UK ) S4 and have changed the oil and oil filter, spark plugs, ignition coils, air intake, cabin air filter and just changed the centre brake light. How do you remove the supercharger to inspect it's state? You done a video on this? And what is the air intake model ( looks like an IE/ K&N mode ) or is a combo of aftermarket products? Again, great heads up on what to expect. They go like the wind, if serviced properly. In manual and sport mode, they really go for it without any lag; in drive, they're not great, but I guess a remap will change that. Noticed my MPG increase when the spark plugs and ignition coils were changed. Great news.
Love my 3.0T TFSI Great maintenance recommendations. There is an RKX PCV valve rebuild kit available that works as well. I used it myself. About a $35 part using Viton seals, labor is what it is.
I noticed my waste gate valve is lose, which means the turbo has to leak boost. But not enough yet to trigger the check engine light. Car is under warranty, what should I do? Would hate for it to trigger the check engine light after warranty expires..
71k miles on my 2013 Q7 with the 3.0T, pvc valve replaced twice, cold start rattle once or twice a day but it won’t last over a second, overall mpg around 17. Put a kn air filter on it last year and went back to the basic paper filter because it threw the only check engine light I’ve ever had on it. Driven it all over Mexico, US and a little bit of Canada. It isn’t Toyota reliable but it’s quite dependable.
can you please tell me when to change the timing chain,belt tensioner,water pump, thermostat, harmonic balancer/flywheel??? Also is electronic power steering a common issues in these cars ? How to avoid that
@@johnysilvester8483 I would just keep doing normal scheduled services by my own or with independent mechanics until it gets over 120k miles and then worry about those items or if something is going out then better off by replacing or repairing. From the power steering I get sometimes whining when cold but just be sure to have the correct VW fluid clean and green as it should be.
Awesome video, Been having S5 for a while, sometimes when I press acceleration semi hard say up to 5000rpm it turns to be jumpy, what could be the course? Like it wud go normally then right before shifting it wud jump up 1st
I have an early model 2012 A7 with this engine and I am getting a short rattle on cold starts. Car has barely 70,000 miles and the shop where I take it recommended replacing both of the tensioners. Not cheap at around $1600 parts and labor. I am the third owner and the car was Cpo the second time around. Any detailed videos on how to do it would be appreciated. Thanks in advance.
Hi Federico Pivetta, sorry to hear about your chain tensioner rattle. Audi recommends if the chain tensioner rattle lasts longer than 1 second to replace both the bank 1 and bank 2 upper chain tensioners. We will add this to our internal list of DIY topics and you may see it covered in a future video!
That’s Alex Rogan the mythical magazine writer. Great Video, it would be great if FCP had the parts and tools to resolve these issues posted on the website. I was looking for the timing tensioner shown for a 2015 Q7.
I'm interested in a s4 b8 and I'm very concerned about the chain tensioners. If the new "reinforced" ones from Audi are installed, will the problem go away? Could not changing them harm the engine? How long does the repair take, 100k miles? thank you
Oil might be slow burn over time, it’s common on 3.0t. I switched to liquimoly 40W. Still happens though I couldn’t tell you for certain that it slowed or not.
i have a 2014 a6 c7, i just modded the exhaust system, theres some drone when going 80 mph on the highway any idea on what to do to get rid of that?, and i kinda noticed the car rattle a little and shake here and there on idle.. you think its the ignition coils? I just replaced the spark plugs. very informative video though! Subbed.
Hey thanks for this video, I've been owning a "13" a8l 3.0t for awhile and I notice a foul smell when the ac is turned on.

Thank you for that, Mahdi!
I have a B8 S4 and can attest to the robustness of the 3.0T. I think Audi knocked it out of the park with this engine. These make enough power to run 12.9's with the right tires and launch all day long. Put a Stage 1 tune, intake system, and S/C pulley and be deep into the 12's and not worry too much about breaking the engine. The transmissions are another story though. It's hit or miss with those. If you have an early DSG, you might want to keep a spare on hand to change out preferably from a later model. Just putting this out there for those who don't know, a new one is 14K from Audi. Yes, that is fourteen thousand dollars.
Really? I've heard they're generally robust as long as you do dsg filter/fluid/gasket services every 80,000km
Correction, you have a (B8.5) S4 if it's the 3.0T, otherwise if you have a B8 as you claim it would be a 4.2 Liter V8
@@SuperEman500 B7 had the 4.2 v8, B8 has the 3.0t, b8.5 is the 2012 facelift of the B8 also with the 3.0t.
You might be getting confused with the s5 which retained the V8 for a while after the 3.0t came out.
@@SuperEman500 wrong

Just got a '15 Q7 S-line Prestige, 100k mi. Still drives like new. Definitely checking everything in this video! Great job!
Right on!
Excellent and precise content! I have this motor in the A6 and no headaches except the pcv valve replaced and 2 seconds chain rattle in the morning on cold starts.
Such a great engine and very easily tunable to upwards of 400 hp.
Thanks!
THAT'S WHAT IT IS. OH MY GOD I NEVER KNEW
Super capable engine jj. Glad to hear yours have been fairly care free!
This video is absolutely god tier with the useful information I CANNOT THANK YOU ENOUGH!!!! 🎉❤
The lay out of everything is so great! Ty very much. the confidence I have now to buy a car with this engine is great,you were so clear and detailed, ty again .awesome! You might be do for a raise buddy ,lol
My '12 S4 had a recall on the thermostat several years ago, so I had the dealer replace it free of charge. So far, no issues and I still have the "garage princess" which is dressed in Stage 2+ APR, Vossen Wheels, Enlaes rear splitter, APR Big Brake kit, lowering springs, sway bars an Armytrix exhaust which is bananas. It's been a solid car!
Just bought a Q5 3.0 and this video puts me at ease for choosing this model over the 2.0T! Very informative! Can't wait for more DIYs on this fantastic and fun engine! Keep up the great videos 👍👍
Congrats on the new purchase, T Sal! We'll keep the videos up!
Great video. Honestly most of these things go bad on all other vehicles as well.
Thank you for these videos, they are absolutely great, for someone looking to own a B8.5 soon, they are super super helpful, and the production quality is top notch.
Look forward to more :)
Thanks Joe! We have more coming for sure. Using videos like this will save you quite a bit of money throughout your B8.5 ownership 😉😅
Great video! I'm a staunch BMW guy but really like this motor as it seemingly has no show-stopper issues. At a glance this is a lot more solid than an N54/55 that have a litany of things to fret about...
You wouldnt be wrong in thinking that Stephen... especially when comparing to something like n N54
Yeah just picked up a Q7 instead of the X5 bc there are just too many common n54/n55 engine issues that all cost 2k+ or an entire weekend of wrenching in your driveway.
@@ALE5six1I’m currently shopping a 3.0T Q7 to replace my 08 335i! I’m kind of shocked wt how many people cross shop the platforms
@scott8934 well bmw and audi are pretty similar being both luxury brands from Germany. I tend to like the user setup of BMW but audi's can be more reliable. I've only owned my audi for 2 years so we shall see
@@fcpeuro ....life's irony.....3 years later and I've just acquired an e92 335i N54 DCT 🥴🥴....wish me luck!
I purchase all my parts for my 16 A6 3.0T from you guys! FCP Euro rocks! nobody comes close to your prices! He is completely correct the 3.0T is highly tuneable, got APR stage 2 tune with supercharger pulley upgrade put on a week ago and from fast to stupid fast!
Thanks Dan! The 3.0T can be a real monster for sure, be safe with that beast of a motor!
Nice! I’m thinking of purchasing the same APR SC pulley & ECU Stage 2, any update on yours after a year?
I appreciated the review of the 3.0t. I bought a 2014 A8 (two years ago) and it has performed well. You very accurately explained the initial "rattle" that I hear upon start up and while it goes away in the prescribed time., I may get this looked at just to be on the safe side. Water pump and thermostat will also be serviced as well. With the supercharger off, I may have that serviced along with the PCV replacement since the labor will already have those components off the engine. Great video - glad I came across this and subscribed.
Looking forward to a DIY video on the chain tensioners. Could really use that, if I ever have to do it.
@fcpeuro please!
Yes that would be great
audi`s best engine
Great video. You forgot to mention the flex pipes rattling. Most commonly the result of the motor mounts going bad.
Just got a Q5 3.0T 54k miles I’m so ready to make this thing a beast
Great video. I dont afraid 3.0 TFSI anymore and im going to buy one. Thanks man
I'm in the process of buying a B8 S5 in the next week or so and being someone who hasn't owned an Audi before(I'm an Alfisti BTW) I was afraid of the unknown but this really gave me an idea of what to look out for. Thank you and keep it up!❤😊
Good choice!
What is the consecuence if we ingore the secondary airpump foult code ? What problems it brings , on a 3.2l engine Q5 2009?😊
The secondary air injection pump or SAI pump reduces the carbon emissions from a vehicle’s exhaust. The car's air injection pump also helps increase the catalytic converter's efficiency. Suppose your vehicle has a bad secondary air pump. In that case, hydrocarbon fumes will come out in an excessive amount from the exhaust., not to mention the pollution added to the environment.
You Should have mentioned the silicone gasket on the timing chain cover in the back of the engine. Very prone to leak since it is a silicone gasket right above the hot exhaust manifold. It’s an even more fun job if you strip the small torx screws, speaking from experience they stripped with barely any pressure by hand.
Very good point, thank you!
Incredibly informative and helpful, subscribed immediately after watching this. Shopping for a 2015 A6 3.0T and I'm a little concerned about the timing chain rattle issue. Some say it's not an issue, some say it can get worse over time as the age and the mileage of the car goes up. Is that something to be concerned about?
Driving a 3.2l FSI at the moment, would love to see a video like this for that engine as well.
i heard about this on the A7
I hade an Audi A6 from 2005 with the 3.2 fsi engine. Mine wife goes to shop and comes back and the car wouldn't start anymore. Went to Audi, repair would cost €8400 they said ! Distribution/ chain problem. It happened arround 255 k kilometers, I don't know how much that is in miles. Bud for me, no 3.2 fsi engine again !
My tech said it depends on how often oil changes were being done
My cousin recently pyrchased a 2012 3.0T in an S5 cabriolet. (Midlife crisis mobile) Had it a few months but had only driven it on nice weekend afternoons. Stated that it had started to indicate low coolant. Unsure how hot it had run. He had added coolant 'a few times'.
Had coolant pooling all over beneath supercharger. Front of engine had obviously had coolant leaking down it for a while. Water pump spun exceptionally freely, had issue with coolant pipe at thermostat housing, and passenger side 'window' of pcv valve/ oil separator was discolored.
Just had a couple of pulleys, tensioner, belts, water pump, thermostat, pcv valve/ oil separator, several all hoses, the front coolant crossover pipe, the coolant pipe from the rear of the thermostat to the rear of the engine, and the pcv lines from the valve to the valve covers changed.
Engine surged between 800 and 1200 rpm at idle.
He states that it runs great under load.
Has a P0068 and also a MAF/MAP code. Has a sound like a vacuum leak at rear of head on passenger side of engine.
Throttle body and plate, as well as manifold cleaned as far as could be reached.
5 vacuum branch lines checked and are all intact to respective devices.
Shop owner is stumped.
Cousin and I have found several articles/ threads with this problem not being identified after substantial repairs made.
** Pcv valve was O6E black, and was replaced with O6E.
Have heard of issues with alternate pcv valve, cracked intake, and a possible egr valve issue.
Starts right up and runs smooth for 10 or 15 seconds, then starts surging.
Thanks in advance for any thoughts.
That was very helpful because I’m looking at getting a 2014 Audi s4 with 77,000 kilometres on it so when I get it I’ll do a health check on the engine and see if everything is good and look at all the service records
Very informative. This video is blueprint material for Audi owners.
Glad you think so!
This video was so good! Only thing it was missing was average price points for parts but other than that very throughout
unfortunately prices can change over time, so what the price points are currently may not be the same in a few years
Just put a deposit down on a 15 Q7 S-line with 107k on it. I plan on getting the JHM ecu and tcu tune right off the bat. I may just do some preventative maintenance on some of these items as well so I can have some piece of mind. Great info here
For someone whos in the market for a s5. This is an ideal vid. Thanks
Glad you liked it
My local audi garage claim they need to take the engine out to change the chain tensioners. Needless to say that is expensive. Are you sure it can be done without taking the engine out
Oil filter housing gasket, oil cooler gasket and rear timing covers themselves (on the earlier motors, seems to be better on the newer ones) are a couple more common oil leaks
I own a 2015 q7 prestige and that engine seems pretty reliable not issues at 60k miles
That's great to hear!
Should include the plastic coolant tube that runs in the engine valley. Seen quite a few leaks from them cracking.
Thanks for the suggestion John D, I'll pass this along to our Audi Catalog Manager!
@@fcpeuro This is a must.
Just picked up a 2010 A6 for super cheap this weekend, from the ticking sound it's making it sounds like it'll need the timing chain tensioners, would like an in car diy on that
I really love to drive Audi...10 year to drived Audi S4 2012 and now SQ5 2020
The fella from Facebook is a real car enthusiast
Can we get the DIY / Instruction of doing timing chain tensioner? 😬😬
90 year old t boned and totaled my mk6 GLi. I think I might upgrade to one of these
Id like to add to the PCV valve section, that it can cause some massive coolant leaks that you have no visible indications of besides coolant and oil mixture. The gaskets actually failed on my as well and was spewing some coolant into the open bay area around the PCV. So for anyone watching, it took me a bit to find this on some forums but there is information out there on it.
Great note, thank you!
Sold!!! I'm pulling the trigger! Thanks!
Don't forget the oil filter housing seal ( S4, S5 Supercharged engine).
I replaced mine at 75,000. 2011 S4.
Also replaced PCV valve, crossover pipe from the back of thermostat to firewall, water pump, and thermostat.
Big job and long hours.
Very comprehensive video 👍 thank you very much, Im now the second owner of a B8 S4 and its also my first Audi. There's a lot to learn but this definitely lays a nice ground work for what to watch out for. Been working on cars my whole life but never anything like this, absolutely loving the car
Glad it was helpful! Enjoy the new ride 😎
The timing chain tensioner TSB should apply to all 3.0T cars... My '15 S4 rattles for about half a second on startup but has become more consistent on cold startups over time. I try to ignore it but it just sounds so bad haha. Still love the car though!
If you turn up your music loud enough there is simply no problem. But we do agree the TSB should carryover to all 3.0T Cars
I was an Audi tech for 4.5 at a dealer. It does apply up to the 2015 MY cars and I've done them on 2015 S4s and Q7s.
Great info! would love to see this kind of video for the 4.2 FSI in the RS5
Most of it is the same. Thermostat, water pump, engine mounts (funny enough I've already replaced all of those on my rs5) as well as you'll need constant carbon cleans, camshaft positioning sensor goes bad, and timing chain tensioner have a similar issue as in the 3.0T as described. Sparks and coils are also the same as in this vid
@@mattw4211 Thanks. Good to know most of the common issues are easy to fix. I just picked up a 2015 a couple weeks ago with 37k km on it. I've read a couple forums talking about transmission failures which are probably my biggest concern at this point.
@@mattw4211 if you don’t mind me asking how much total for costs ? Been really thinking in pulling the trigger or just get a more care free TL SHAWD. Just not as of a looker as the s4
Question. How much costs to change timing chain in US? I mean at 3.0 supercharged engine. Can you make video how to do it?
Great video and very informative. I've a 2014 ( UK ) S4 and have changed the oil and oil filter, spark plugs, ignition coils, air intake, cabin air filter and just changed the centre brake light. How do you remove the supercharger to inspect it's state? You done a video on this? And what is the air intake model ( looks like an IE/ K&N mode ) or is a combo of aftermarket products? Again, great heads up on what to expect. They go like the wind, if serviced properly. In manual and sport mode, they really go for it without any lag; in drive, they're not great, but I guess a remap will change that. Noticed my MPG increase when the spark plugs and ignition coils were changed. Great news.
Thank you for this video... specific, detailed, and insightful... really helpful!
You're very welcome!
Love my 3.0T TFSI
Great maintenance recommendations.
There is an RKX PCV valve rebuild kit available that works as well. I used it myself. About a $35 part using Viton seals, labor is what it is.
Thank you fcp for all the great information
Our pleasure to share it with you Elias Bako!
I would love a video like this on the SQ5 3.0 tdi (V6T) engine! Also mention the wastegate valves that start leaking on the turbos,.
I noticed my waste gate valve is lose, which means the turbo has to leak boost. But not enough yet to trigger the check engine light. Car is under warranty, what should I do? Would hate for it to trigger the check engine light after warranty expires..
Very insightful! Thanks FCP!
Glad you liked it!
How reliable are the chargers? And what maintenance do they need? Especially a tuned one?
71k miles on my 2013 Q7 with the 3.0T, pvc valve replaced twice, cold start rattle once or twice a day but it won’t last over a second, overall mpg around 17. Put a kn air filter on it last year and went back to the basic paper filter because it threw the only check engine light I’ve ever had on it. Driven it all over Mexico, US and a little bit of Canada. It isn’t Toyota reliable but it’s quite dependable.
You have that cold start rattle too?
@@thenotoriousjoey9956 yes, I get it on most cold starts but if it goes right away there’s nothing to worry about.
@@armandobenard2251 I get it too on my s5 I just got a 2015 with 45k mikes it goes away fast as well
can you please tell me when to change the timing chain,belt tensioner,water pump, thermostat, harmonic balancer/flywheel???
Also is electronic power steering a common issues in these cars ? How to avoid that
@@johnysilvester8483 I would just keep doing normal scheduled services by my own or with independent mechanics until it gets over 120k miles and then worry about those items or if something is going out then better off by replacing or repairing. From the power steering I get sometimes whining when cold but just be sure to have the correct VW fluid clean and green as it should be.
Thanks for the video. Can you make one on service and maintenance? Dealer told me 10,000 miles for oil while you said 5,000. How come?
We will make one on cost of ownership and maintenance. Should clarify some things !
Any updates for this legendary video!? Or maybe addons? Thank you!!
Thank you
Many thanks. Been dragging my feet on pcv replacement
Its time The_Tech_Geek 😁
How much will that cost?
Hi there can talk about the gearbox senor on a B8 nd B8.5 serious problem..how to get it sorted out. Brilliant video
We have one coming out on transmission/drivetrain soon DEE ATKINS!
Great informative vid thanx. If it helps, another symptom of a failed PCV is coolant loss which is not visible anywhere until you remove the SC
i loss 1 liters of coolant in 100km and its not visible i dont know the other symptoms its the PCV valve or cylinder head gasket what you think?
Awesome video, Been having S5 for a while, sometimes when I press acceleration semi hard say up to 5000rpm it turns to be jumpy, what could be the course? Like it wud go normally then right before shifting it wud jump up 1st
I have a 2013 a7 and and when it start up makes a clicking nosie when in park and once it going 20+ nose stops what could it be ?
I have an early model 2012 A7 with this engine and I am getting a short rattle on cold starts. Car has barely 70,000 miles and the shop where I take it recommended replacing both of the tensioners. Not cheap at around $1600 parts and labor. I am the third owner and the car was Cpo the second time around. Any detailed videos on how to do it would be appreciated. Thanks in advance.
Hi Federico Pivetta, sorry to hear about your chain tensioner rattle. Audi recommends if the chain tensioner rattle lasts longer than 1 second to replace both the bank 1 and bank 2 upper chain tensioners. We will add this to our internal list of DIY topics and you may see it covered in a future video!
@@fcpeuro Thansk so much.
thank you for this video ! very informing for a new S4 owner like myself 👍🏻
That’s Alex Rogan the mythical magazine writer.
Great Video, it would be great if FCP had the parts and tools to resolve these issues posted on the website. I was looking for the timing tensioner shown for a 2015 Q7.
I'm interested in a s4 b8 and I'm very concerned about the chain tensioners. If the new "reinforced" ones from Audi are installed, will the problem go away? Could not changing them harm the engine?
How long does the repair take, 100k miles?
thank you
Thanks for this, I have both a slow coolant and oil leak so hopefully I'll get to the bottom of it!
Oil might be slow burn over time, it’s common on 3.0t. I switched to liquimoly 40W. Still happens though I couldn’t tell you for certain that it slowed or not.
i have a 2014 a6 c7, i just modded the exhaust system, theres some drone when going 80 mph on the highway any idea on what to do to get rid of that?, and i kinda noticed the car rattle a little and shake here and there on idle.. you think its the ignition coils? I just replaced the spark plugs.
very informative video though! Subbed.
Nice video!
Any tips on transmission problems with this engine??
I have a A5 3.0T from 2014
Hey thanks for this video, I've been owning a "13" a8l 3.0t for awhile and I notice a foul smell when the ac is turned on. I've replace both cabin and air filters as recommend but still the smell remains, I'm thinking my drain valve is clogged and I would like to know where its located and how can I unclog it?
Hi there. Did you ever found out how to do this? I have the same issue on my A8. Thanks.
180k has oil consumption issues bad oil leaks and the motor is going out but still running like a champ may I not for get the timing chain rattle for about 5 minutes till warm
Great video... thanks. You guys are great.
Have you made any video replacing the PCV/Oil Separator on this engine? I have a Q7 with this engine that is presenting some issues with PCV. Great videos, thanks
It will be going live not next week but the week after :) We shot it yesterday.
