I took the car to the audi center here in Norwich. they said the timing chain tensioner has to be replaced, may be both right and left one and it's going to cost me £2558 total. They suspected that the cylinder head may have been damaged as well and replacing that as well will cost be in total of about £5500 in total.

I have no knowledge of mechanics and I would like to learn the car mechanics and fix the car DIY in my garage. I am in Norwich, UK. Is there anyone who can help me ?

Just to let you know I had this same wiring changed back in Sep 2016 which connect to the throttle body and the car ran fine for some time until Feb 2017 which started with the same issues and same code P0201. I now have had the gas pedal and wiring changed. The car is currently at the dealership now and they are saying the full engine wiring hardness needs to change at which I laughed and said sure I will do it for the $4k but if I ever get this problem again Audi pays for every thereafter repair at which they laughed...

I am shocked Audi cant solve this problem which seems to be happening to many.

Default Hi guys new to the site

Hi guys I’ve had my S6 for 4 months now and this epc problem has shown up it was coming and going a few months ago but now it isn’t going anywhere by the looks of it. I work in a garage but have very little time in and out of work to resolve this problem. I’m going to have the wiring and electrical plugs/connectors changed on the throttle bodies hopefully sometime this week.

Hi it took me some time to locate the fault. But it was the injector wiring harness the plug had some corrosion. I ordered a harness but ended up cleaning the original harness plug out. It ran brilliant for 5 weeks before I sold it. Hope this helps if you haven't sorted it already.
