Audi A6 2001 Tiptronic TDI Wiring issue.
Bought this car as project for myself, and found out couple of weird wirings.. main issue is its running roughly on idle, and smokes alot.
But the question is can someone kind tell me what was the idea connecting 4 wires straight from the ecu wires to this pin behind steering wheel? (hopefully theres a pic) it goes in behind left whisker.
Sorry for my horrible English..
