Hi guys,
I got some problems with my a4 99 1.8t.
My check engine is lighted and my revs are pretty high at idle, like 1500 and sometimes 1800 when the car gets hotter. i connect it with vag-com to solve and find the problem but when i go to do the basic settings. I have a error message appearing which says that he is unable to do it.
Can you guys help me please.
