MK6_604
Passed Driver's Ed
Hello everyone, I am in the process of diagnosing my currently broken mk6. Ill give you guys the back story. Any help or insight would be wonderful. So here goes...
I was driving my car the other day and felt a very strong hesitation when I went to accelerate at normal city driving speeds. I set off from a stop sign as you normally do, 1st gear, 2k rpms to 2nd gear. I went to give it a little bit of throttle maybe 20% in 2nd gear just to get up to speed because there was someone coming up behind me quite quickly. My car hesitated and became very sluggish and I immediately thought to myself *misfire*
I immediately see the check engine light flashing so I put the car in neutral and coast until I see a safe spot to pull over 5 seconds down the road. I shut the car off and I read the code on my obdeleven and it reads a misfire cylinder 4 code and a random/multiple misfire code. I clear the codes to see if the car starts... and it just cranks, no firing. I then swapped coil 4 and 3 to see if it would start and then the misfire would follow. The car just cranked again...
I always keep a set of ignition coils in my trunk so I swapped those in (slightly used oem bosch) for the genuine oem R8 coils (not knock offs) i had installed at the time. Same thing, just cranking, no firing. So I go back to the R8 coils and give it a bit of gas on while trying to start it and it fires up hesitantly.
It was idling like it had a misfire and the cel came back on so I shut it down to read the codes again. The current codes are misfire cylinder 2&4 as well as the random/multiple misfire code.
I had the car towed to my work (I work at a porsche dealership) and had a former VW technician of 20+ years briefly look at the problem. He had me attempt to start the car (just a few cranks to see if it sounded like it had compression). He said it sounded like it had compression. That's where we left things until tomorrow morning, we will be doing compression testing.
Important things to note:
-My car has an APR downpipe and their most recent 'stage 2' software, a K&N intake, southbend stage 2 clutch
-2k kms ago I installed a fresh fuel filter (6.6 bar revision), ngk bkr7eix plugs, and genuine oem R8 coils from DAP.
-my car has 111,000 kms on it and I do oil changes every 7k kms
I have 2 possibilities in my mind right now. I think the timing chain tensioner is done, or it is a fuelling issue.
Thank you in advance for your response
