Yeaaa I had a little hick up with the second part.... forgot to start the camera recording and yanked the manifold out while talking to “my self”.... but still coming right up.
My 4th was misfiring, everything fixed according to code and now runs worse which they never seen before. I know they added fuel or injector cleaner on an empty tank and seen it run worse at first before but this seems different.
Hi serge had you had a chance to check the fuel rail residual pressure before removing the intake ? I personally like to do this test with a cold engine because with a hot engine the fuel pressure all ways goes up in not in a long time I usually test them for 10 to 15 min and the rail pressure should drop a bit compared to idle but not drop too fast I remember seeing a Audi TSB for the 3.2 v6 engine I follow the same specs for the 2.0l and it serve me well then again I do this test with a cold engine I start it and let it run 10 seconds then shut it off and turn the key on and observe the rail pressure and see if any injectors are leaking i also like to clean the injectors tips when I’m reusing them I use throttle body cleaner and a plastic brush or brass I think the car runs better afterwards including the intake valve service anyway can’t wait for part deux.
No I didn’t, so far all the injectors that I have seen leaking, were leaking so much that I would start the car cold, turn it off right the way and take spark plugs out and see which one is leaking... this one didn’t do that:)
Should I take out the fuel pump fuse before I do this test? I'm actually trying to get oil in the system before I start the car, I just did the timing and it sat for awhile before I finished the job. What do you think the best way to make sure the system is properly lubricated (primed) before I start it up? Great video again! Cheers
l was doing the same thing and the car sat down for a while and it was working fine but after yesterday when l completely sealed a oil leak from the vacuum pump the car after few minutes of driving it it give me misfire on cylinder 1 and after driving it back home cylinder 1&3 now sometimes when l swapped the spark plugs and coils says cylinder 1&2 are misfiring
Great video! Diagnosing this with cylinder 2 now. Which vagcom version and connector type do I need for a a4 2.0t b8? Is it USB-HEX? I have it for b5/b6 but I haven't got it yet for the b8 chassis. Cheers!
Hi Edge Motors I love your guys videos I have a situation with my B7 2.0t. I'm getting surging in my idle. It happens, when I'm under load between 2 to 4000 RPM, up and down up and down up and down. I changed numerous of things. But I suspect they could be the torque converter. Have you seen this? Thank you so much for your help please help thank you
Not sure if you ever got is situated yet, or if your TC has failed yet, but yes, that’s an early warning sign of TC failure. Some have found relief with a transmission fluid service. Some will last forever like this, and others catastrophically fail. Happy Audi-ing 😝
I’m having a misfire in my 2007 a4 b7 in cylinder number two I changed my hpfp didn’t do anything I saw that my coil clips are so brittle and they are a common problem with these coil clips so do you think it might be that causing my misfire. I might bite the bullet and purchase the clips and replace them because there not that much.
@@erictech201 hi, me Audi4ever, you see the hose that connects to your intake from your PVC, disconnect it from the intake , as you plug the intake with your thumb have someone start it, and see how it runs then
While I don’t have one I am trying to help my neighbor who has a 2009 Audi A4 2.0T . She has CEL codes showing $7E8 & $7E9. Shakes when idling, Runs really rough. I haven’t driven it yet, but she says also has lost lots of Power. Poss PCV & PRV Valve? I’ve read up this could be the problem in lieu of Spark Plugs, Coil Pack, which is what I was thinking it was. I’m not a “mechanic” but a big DIYer that has worked on many vehicles, but never an Audi. My OBDII/EOBD scanner I am using is a CenTech Deluxe, which also shows live sensor data. While It’s not a Snap On or even close, it’s been able to diagnose & solve many problems from many diff makes of vehicles. Unfortunately, she is a bit strapped for $ so, trying to help her out. If Spark Plugs, how easily are they to change? Also what gap & kind? I recently just checked my coil pack & changed my spark plugs on a 2003 Jeep Wrangler that was having misfire probs. I upgraded to Iridium plugs in my Jeep. Should I try to reset her codes 1st & see if it has a misfire code also come up, before diving into this problem? TIA, your knowledge is quite helpful.
2015 a3 2.0t quatro. Serviced by audi since new, cylinder3 missfire, audi diagnosed catastrophic piston/ring failure. Told me I need to pay for a new engine to be installed. 69k miles owned and driven by my wife. Smfh... known problem w these cars
Thanks for the video ! Love it ! My 2008 A4 wagon is doing the exact same thing. I changed out everything ie ngk plugs, coils, pcv, 4 brand new oem injectors and even cleaned out 90% of the carbon build up on the intake valves when pulled the intake manifold off. I'm doing a compression test and crossed my fingers it isn't a blown head gasket. Any ideas is very much appreciated. Thank you in advance.
@@4Kreflex No i have not. Kept pulling codes but it's so misleading. I won't change injectors just yet if I were you. I even swap out the throttle body for a new one thinking my oem was faulty. But damn. No change.
Hi. Thank you so much for responding. Negative. I don't even have any build at on my spark plugs. They are in normal condition usage. I changed them out because of regular routine maintenance.
@@onememories8523 I noticed that my issue is loss of power. I don’t know what else it could be? I have the injectors in hand just need a mechanic for the job.
I’m getting a cylinder 4 misfire, and random misfire, I checked compression all cylinders are even. Tried moving coil/new injector/new plugs no luck ...running compression test I get 52 on #4, 62 on #3, 72 on #2 and 72 on #1. Valves are cleaned recently so carbon is ruled out any idea ?? Thank you
My misfire occurs at idle no matter the engine temperature. Some days no misfire. This is typical of carbon build up on the intake valve which changes the way air flows into the engine. Mk7 E888 Gen. 3
Is it safe to drive the car with one cylinder misfire for some days at low speeds? The engine is shaking quite often while accelerating. The fourth coil pack is faulty and i'm getting to replace it after some days.
@@baulshur530 Yes, i changed the damn coil and the engine is smooth again. Actually i bought all 4 new ignition coils, because they cost like pennies. And i don't want to have the same problem again! (engine shaking, hard to accelerate etc)
I have a misfire in Cylinder 4, pressure is 50psi and others are around 155/160. Is this an expensive fix? Dealership says it is. My 2015 Q5 has 180K mikes. Should I just get a new car?
It ended up being the injector, I made the video, but my editing software corrupted the files, I’m trying to fix it, I’ll post the second part as soon as I will
Guessing VVT solenoids. Sent mine to the garage and they told me it was because my car had a tune and it must be the chip... swapped the solenoids around and the code followed after getting a code reader... never to the garage again. B8 A5 2.0 TFSI
I have a stage 1 apr tune, did timing, PCV, carbon cleaning, colder plugs, smaller gap, fuel trim is normal, no codes and still get random misfires in 3 and 4 every so often, compression is good in all cylinders, I’m stumped as to what it could be. The colder plugs and smaller gap reduced the regularity of it but still happens once or twice per drive
Might be you fuel have higher octane rating then what it’s tuned for if you add octane boosters then it could randomly misfire and vise versa if octane is lower from what’s car is tuned for. I had misfire pretty bad on my a5 that’s got stage 2 with DP, CAI, big Intercooler even with bigger throttle body diameter and the issue was camshaft sensor put an old one I had laying around and misfires stopped.
DUDE ,,,,,,,,,,,,,YOU NEED A SCOPE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If your car is still misfiring after changing plugs and coils. Try to clean your o2 sensor, i did that and the misfire stopped instantly
Thank you, thank you, thank you!! I checked and changed everything. I did what you said and it help so much. Thank you!

@@EDGEMOTORS hey, how would you diagnose the cause of a P0327 on a 2.0T. Also, to replace the knock sensor only way is to remove waterpump?

It's the PCV valve and make sure the spring in the replacement pcv has a lighter spring in the diaphragm
