I have manual a4 b8 quattro 2.0t, check engine light was already on but EPC light came on and then would go back off. Have done a lot trying to figure this out and cannot find the diagnostic, doesn't have a rough idle or anything, car trys to turn over after stall and sometimes it will start right away and sometimes it takes a couple trys. Please help, here's the list that came from my VCDS. I did notice the engine control module but haven't got too much into electrical with this and am unsure if that will help. Thanks, all the help the better. ( figured just copying the whole list would make it easiest )

You need to fix that MAF issue. It has the ECM unhappy, which makes the ABS/ESP unhappy. But it lists it as intermittent. Clear DTCs and see what comes back.

ESP button on the dash is jammed? Is this error expected? When you press the button, does ESP trigger between off and on as expected?

"B8", ok, so it could be a MY09-MY16 A4, MY08-MY17 A5, or MY09-MY17 Q5. :-) We figure it's an A4 since you're here, but what's the actual model year? I'm guessing MY10-MY12 since I don't see a tire pressure control module in your module list.

Have you looked to fixing the G395 error? Device on the front left of the radiator with a plug in it? Thing is not an uncommon problem on the B8.0, but it could be the sensor or the wiring to it. Still, it's a relatively cheap and pretty easy thing to replace. Is your A/C working otherwise?

Your scan log is truncated. You have errors in 42, 46, and 56 that are not posted.
