You need VCDS scan. It will tell much more than only that one code.

I am having the same issue with my A8. Same codes too. All O2 sensors have been replaced, PCV replaced, and Spark plugs replaced. The fuel filter is on order and Its time for a new battery this week. Ive been following these ECP problem threads for a while now. To no avail. Oh and Ive searched for vacuum leaks EVERYWHERE. NOTHING. I will be following your thread. Hopefully one of the AudiWorld experts can shed some light for the both of us.

Hello Liljoey,
You do realize that this thread is from 2014, and dildildil has not been active for the last 15 months...
Being you state that you have the same codes as the OP, did you check either G187 or G188, it seems you have done everything but.

I certainly hope its not the ABS module again. Had that replaced about 6mo ago by Audi service shop here inGermany. Think Ill be taking your route and let her go. Im up there in age as well and am losing interest in the constant issue with it.

Appreciate the quick response.

I had this exact issue. Ended up replacing the throttle body with an ebay one. Since then it hasn't surfaced.

Thanks for the reply GIOVANNI. LOL. I noticed after the fact. Appreciate the throttle control note. I have in fact taken it apart and gently cleaned it as other threads have suggested. It was good for about 60 km and started with the same issue again. EPC/ESP, horrible fuel consumption etc. so I clear all codes and do it all over again every 20km or so. Story of my life.
