Have an 06 4.2 and it's been a great engine. I guess the cam tensioners are probably the worst on the list to do but it is what it is.
Great video. This has definitely helped me in my purchasing decisions. Looking forward to future videos. Keep up the good work.
Great overview! Love your editing :)
Thank you for this kind of videos! I'm in the market for one and this came out with perfect timing!
As always great info. Great move with actually showing yourself ;) thought ur much older mate 👍😉
Great video! Thanks for the info
have had a8s with both engines and both have had over 200k miles with little issues. The oil cooler leak was the only issue that had to be done on the older 4.2 and just injector replacements on the newer 4.2
I'm about to replace and injector. the job seems easy
Thanks Emerson! That makes me feel better. These cars tend to scare people even though resale is low. I do my own repairs so unless a part is outrageously expensive, it is worth it. Even if it is, I am still not paying for labor. I have an 08 S5 and it is so fun to drive. I love the A8's. Pure Luxury.
Keep up the good work. 👍
I always look forward to ur videos and ur opinion on cars. U always do research on the maintenance and include and estimate to fix.all my questions always answered by ur videos..thank u
Very informative thank you , this video has provided me with a definitive ancer to whether my engine has a belt or timing chain yes it has both and it's on LPG
You dont have both you have one or the other
the plastic chain tensioner shoes can be purchased on a few sites, and just those changed. The plastic becomes brittle with age and heat cycles - then they crack/shatter and then you can have 40 valves bending on the pistons. can remove tensioner and pop off old shoes and pry on new shoes. Need a stubby torex 30 bit to crack loose the cam caps. the HARDER thing is re-sealing the valve covers to prevent leaks - overdo it with RTV on ends and bottom edges of cover.. also RTV the bolt rubber bushings -- this leak goes on to the exhaust manifold so you get to breathe the smoke- not good for your lungs.
interesting, thanks for video
Gostei do vídeo, achei muito informativo e engraçado!!
The only lingering problem I’ve had on my A8 4.2 (FSI) is a stutter/shaking on cold starts, when I put the car in reverse or drive it shudders. Only on a cold start.
I’ve been trying to track down the issue for months replacing little things (sparkies, injector, cleaning throttle body, vacuum leak test), but to no avail.
Luckily it goes away as soon as the car starts driving and disappears after that. Really weird.
Aside from that, great car. It’s ungodly comfortable, great power and just an incredible exterior and interior aesthetic. 160k+ miles.
Check your pcv valve/oil separator
@@fallengamingtv6945If this thing breaks down, it will cause blue smoke.
carbon clean
Please, make an A6 3.2 FSi Quattro engine vid, I saw the vid where you talk about the A6 C6 but just wanna know more if possible
haha man i remember watchijng your vdieos a while backl while i was buying different cars now you show your actualy self i always wondered where u were from lol. Just subscribed i love your viedeos bro keep them up!
This car it's my wet dream. I own an A6 C6 2008 3.2 fsi, definitively I love it but I want more power and size, only for me, driving this big ship gonna be a pleasure, the big size and big presence will make everyone look and have fear from an A8, I love it, saving some $ to buy one soon.
So… im looking for an A4/S4
Diesel 2006+ or gasoline 2000+ (emissions restrictions in all of my surrounding cities)
What would be the most reliable option?
A4 B7 with 1.9tdi?
A4 B7 with 3.0tdi
Or S4 B6 v8?
Thanks in advance.
Love your channel
Great 👍
Thanks for the great vid! You really know your s**t! I have 2007 Audi Q7 4.2 Premium with only 81,000 miles. Sounds like I should sell at 125,000 to 150,000. I love it, though. Found you while researching oil cooler leak. Great job and very entertaining!
Yooo I got the exact Sam car as you 2007 audi q7 4.2 fsi premium it's a really great car although car have a problem at every single piece even the seats and exhaust but it still drive smooth and fun to drive and sound loud it has a weird v8 sound like old muscles car at low rpm almost full throttle so yeah it's really good car I don't feel of all these problems while driving
I bought a C6 A6 to avoid getting the FSI engine. In the end it was dripping oil from somewhere, but I had gotten my money's worth out of the car, so I traded it in. I paid $14k and drove it from 2011 to 2018. I only changed the alternator, brakes and tires.
f man thats quality reviewq you make
I prefer the previous format where there is an abundance of detailed knowledge interspersed with the odd bit of humour. I think you've gone overboard on the latter and the crass language undermines what I think is the definitive resource for used vag vehicle info.
So i bought an a6 4f allroad this march with skipped timing chain. Audi wanted 7400€ for the chain service plus further parts that need to be changed. It was leaking oil from literally everywhere, especially the lower camshaft gasket and from the Oil cooler. Since i have rebuilt the it, its a really nice engine.
Very thorough review thank you
I am
Considering buying a used A8 and I am not looking for one that has naturally aspiration engine with no turbo or supercharger
What year model and what max mileage should I be looking for that remains at reasonable price
Thank you
My brother owns and old 2006 4.2 fsi for 6 years now, engine is reliable but the biggest issues were ABS block which is constant pain, electronic handbrake and suspension.
I peaked down to see if I could access the oil cooler and I did see the cat and the monkey with the umbrella. They were in the way, and even though I asked nicely, they said, "Get lost, Hooman". I guess my temp gauge is where it is supposed to be, so I should leave the cat and monkey alone. I think there was a train down there, too. Ugh. I'll be OK. It is a 2008 S5 with only 35K (miles) on the odometer. Thanks for the info! Very well done video. I enjoyed it and learned from it. ;-)
You'll be more than okay that's a nice car. Also the last time I was at the Audi dealer the only thing with a V8 they had at the place was a Q8 the A8 on the floor was only the 3.0T. The sales man even admitted that Audi doesn't know yet if the 4.0T will end up being as reliable as the 4.2 was.
+1 for BMW N62 and N62TU Engines
Very glad I chose the 3.2FSI instead of the 4.2FSI on my A6. Didn't have nearly as many problems when I owned it.
The 3.2 FSI is such a nice engine!
What issues have you gotten with the 3.2 FSI? Mine is 124,000 km and replaced alternator, spark plugd, some ignition coils at the moment
@@user-pm3dx4te4f I sold the car in April with about 143k miles. The most expensive issue I had was the upper coolant hose cracking. You will also have to do valve cover gaskets at some point. Other than that, nothing super major; I do consider myself lucky for never having timing chain issues.
Egal wie viele Kilometer auf dem Tacho stehen, die Wartung und Pflege sind das A.O
Does this video also apply to the s5 B8
This is why i really wanted and bought an 4.2 MPI und not FSI
Have a D2 with 250,000+ regular oil/filter changes only
I have a 2012 Audi A8 4.2 fsi I’ve been having trouble with the engine late start and misfire with black smoke at the exhaust some times runs fine when and starts within one crank but the real problem starts when it’s at normal temperature it starts to misfire and the engine wouldn’t start without peddle. The fuel regulators and the injectors are brand new still doesn’t solve the issue. If the vacume pipe is removed and blocked which airs the oil then there’s no misfire and no problem at all. It would be of great help if u can get me out of this. And on the The reader says engine rich and no other error codes
Did you ever figure this out?
Hi can you please tell me about the Audi b6 engine V6 3.0 Quattro is bulletproof or it's too bad
soon we will have a video on the S5 V8
Is it reliable ..?
Is it fuel efficient ..?
Is it easy to maintain ..?
NOPE !
But it sounds f.....g great and I regret absolutly nothing 🥲
S5 4.2 FSI CAUA @ 328.000 km still pushing strong
So basically which engine is better built/more reliable? Older or newer?
older
@@differentcarreview-dcr tnx for reply
Leave it to Audi to ruin a perfectly good engine design. The original 4.2 in the D2 was a gem.
My oil filter housing is leaking
I have a 2007 audi a8l with a 4.2 v8 fsi and I’m getting a code p2015 saying bank one sensor is probably the issue any ideas?
-on the intake manifold you got 2 sensors/potentiometers on both sides of the manifold, one should be for bank 1 the other for bank 2
now, there is a technical service bulletin for the seals of these sensors - the rubber seals on them can deform - making the linkage get stuck a bit - and this can cause your faultcode ( here is a link for this issue static.nhtsa.gov/odi/tsbs/2012/SB-10063831-7690.pdf )
occasionally the sensors themselves can be faulty too - if the sensor is faulty then you also get this fault code
-next there are two electronic actuators an upper and a lower, in your case the upper actuator should be fine, but the lower actuator can be already faulty/worn - and this can also cause the fault code
-lastly, inside the manifold the plastic flaps can be seized a bit or too loose - in this case you can also can get this fault code
so long story short: first check the seals on the sensors/potentiometers
if the seals are fine and the metallic shaft is moving freely then the issue can be most probably with the sensor, with the lower actuator or with the flaps inside the intake manifold
if you don't want to spend much money on the various parts then there is a possibility to remove the flaps inside the manifold and to deactivate the actuators - there should be enough info on the internet about this
different car review ok thank you for responding I did order one sensor from parts geek and I will replace it once it comes in since one of them is a bit sticky and the motor is kind of loose but not too loose so and if you push it down and start the engine it moves a little and that’s it I just have to find oil seals for the sensor.
And one more question until I get the part is it ok if I drive it?
yes you can drive it,
but I would be thinking about deleting those flaps in the intake manifold / or at least inspect them, since these plastic flaps can also fall apart and in the worst case - they can get sucked into the valves - not a very common issue but it can happen
different car review one more thing I want to make sure when looking at the engine is bank one on the left side or right side near the overflow tank?
Man that video was hilarious. Not if you're an actual owner of one of those...
We just picked one up for very cheap. Has 117k miles on it and an engine out service is in the works. The idea is change the timing chain and every gasket, the tensioners and then the car is good for 200k miles.
I have seen many examples of these engines lasting a long time, usually a catastrophic failure occurs when the owner avoids an engine out repair. The car is worth such repairs as long as it's replacement cost is less than the repair. It's an $74,000 luxury car so a $2200 repair bill to essentially replace everything that can break is worth it.
Also, engines and transmissions are actually cheap for this so if you do ruin one. The body and frame are aluminum so those will last forever.
Electronics can get expensive I'd a computer problem happens
@@anthonyb.9336 where do you find someone who would do that job for 2200? It's over 8 grand by me just for the timing chain.
@@97336cfI imagine he’s doing it himself and he’s just quoting the price for all the parts. There’s no way you could do an engine out service and replace all those parts for just $2200, it’s impossible
Do you have any info in the ART V8 it can in the 00 A6 v8
So
V8 4.2 good or bad?
my BFM is at 551 000km . nuff said
Wow are you serious, on which model is that
@@kristiankumanov5732 on my audi a8l. It's at 555 000km now
Now at 578 000km.
1:46 🤣🤣🤣🤣🤣🤣💙
Are these the same engines as in the c6 a6?
The newer V8 FSI is the same the other one is not
@@differentcarreview-dcrYou can actually buy the 4.2 MPI with 335hp in the C6 A6; they’re rare but they exist.
@@Swiss4.2 yeah but in the C6 that engine has a timing chain, so its not exactly the same
@@differentcarreview-dcr oh didn’t know, I saw the HP and the fact that it’s port injected and assumed its the same engine in the A8. Thanks for the correction
Can you put a 4.2L v8 timing belt engine into a 2010 A8 L Audi ??? Hate timing chain in back of motor.
The fuckin "random video" clip 😂😂😂
no i dont know about the issues mate, thats why im here lol
What about an Audi A6 4.2 2005 year engine?
Im gonna be honest…on the other videos I imagined that the person who’s talking was an Indian 🤣🤣. Very funny
Same
He sounds nothing like Indian smh ,now he’s accent is European (more like Russian )
Very RELIABLE ENGINES but they are not :P
You do not look at al as I thought you would look like. You always sounded like a 50-60 year old eastern Europe mechanic😅.
N62 bmw engines
So let me write this down, pretty much the engine is a ##^%!!... I have a 2005 VW Touareg with the 4.2 engine. Every day that the car starts I have a new problem! LOL! When it dosent have a problem, it's a great car. LOL!
I wouldn’t say it’s a POS but definitely has its issues, the engine is basically backwards with all the timing chains and important components located on the “back” of the motor. it makes it a mostly engine-out type of job but like you said when it doesn’t have its issues that thing is sweet and purrs like a cat 🥰
so why did you decided to show your face
This guy is kinda hot.
looks like i am NOT buying a cheap v8 a8
какой то гаражный критик ) 4.2 ременной мотор самый надежный АЛО ! Умник х.....
Why so much swearing?
azé mer tudom mennyi pénz, energia és ideg megjavítani és megtalálni ezeket a hibákat, borzaszto ! 😂
@@differentcarreview-dcr na erre nem számítottam:'D jók a videóid, sokat megnéztem már, így tovább:D amúgy f@szán összefoglaltad a hibákat
kösz !
The sound effects and animations having nothing to do with the subject (john travolta) are a distraction and for me make the video not worth watching. Stopped at 1:25.
