ECM failure?
Our 2008 4.2L Q7 all of a sudden has started running very rough (still starts) and has a ton of error codes. This just happened all of a sudden, so it seems one of these codes is the real problem and rest are just related issues. I'm assuming it's the ECM and I need to replace it? Thoughts?
