Hello all...this is my first post and need help to get my sons audi back on the road.
I was recently driving his A4 when I noticed loss of power and extreme vibration. The CEL came on and was blinking. I also noticed the EPC light come on. I quickly returned home and used my cheap code reader to find a fault. It showed P0303 (cylinder 3 misfire). Here is what I did:
- Swapped plugs 3 and 1 to see if problem would move...did nothing. Still had #3 cylinder misfire.
- Replaced with new plugs and ignition coils...zero improvement.
- Replaced all 4 fuel injectors...zero improvement.
- Thoroughly cleaned carbon of all valves...even tried a sea-foam treatment...zero improvement.
- Replaced intake manifold with upgraded manifold...zero improvement.
So I finally broke down and bought a VCDS cable. I ran the autoscan and then cleared all codes hoping one of the repairs I made would correct itself after codes were erased. I started car and almost immediately the CEL came on blinking and car still idled with an extreme stutter.
I don't know where to go from here besides taking it to the dreaded dealership. Hopefully someone can help! Thank you!
