Code P0302 Audi Description
When an Audi vehicle displays a diagnostic trouble code (DTC) of P0302, it indicates a misfire condition in cylinder 2 of the engine. A misfire occurs when the fuel-air mixture in the cylinder fails to ignite at the proper time, leading to a disruption in the combustion process. This can result in poor engine performance, reduced fuel efficiency, and potential damage to the catalytic converter over time.
Common Causes of P0302 Audi
- Faulty ignition system components such as spark plugs, ignition coils, or ignition wires.
- Clogged or dirty fuel injectors.
- Low compression in cylinder 2 due to worn piston rings or valves.
- Vacuum leaks in the intake manifold or hoses.
- Issues with the engine control module (ECM) or sensors such as the crankshaft position sensor.
Symptoms of P0302 Audi
- Rough idle or vibrations when the engine is running.
- Loss of power or acceleration.
- Engine hesitation or stuttering during acceleration.
- Increased fuel consumption.
- Illumination of the check engine light on the dashboard.

I have this code on my 2000 A6T 2.7. Did the coils, not it. Put injector cleaner in it, awaiting results. Replacing motor mounts tomorrow, we'll see. MAF and ICM next in line. Any suggestions?
-
If the coils didn't fix, then unfortunately the problem could be the Ignition Control Module .
-
Hi I replaced the coil pack then swapped a spark plug to see, still not working, changed breather and still under heavy driving the engine light comes on after a while with same code? Is there anything else I need to look into
-
Hi. How are you. A question:
I have to Audi 2004. A4 Quattro 1.8.
Panel light turned on ( check engine. )
Code P0302. The found coolant inside cylinder, so they ll remove head to repair,most likely head gasket. -
Yes, unfortunately the head gasket is the most likely cause of the problem.
-
I know. I already repaired it and I just drove the car 8 days and it came out light again P0302 code
-
Have you done any inspections since the light came back? did they replaced the spark plugs whit the head gasket? is the engine running rough? I apologize for all the questions, just need more information to try to help you diagnose the problem.
-
2010 audi a4 is showing a few codes and thisnis one of them along with 5 others. Im trying to find answers on how to fix the problems im having is much appreciated
-
The spark plugs and the ignition coil are the most common problems for the P0302 code. What other codes you got?
