Question about 1999 Audi A6
As several others on the forum describes i experince the same problem that the cruise control sometimes won't work. Other times it works for some minutes and then suddenly it disconnects?
I had the car to several workshops but always new explanations but still no fix.
What could it be?
This relates to manual transmission: There is a small comment in the manual that says cruise control will not engage if the computer believes this will result in under or over reving the engine. My intermittent behaviour seems to be due to this. As long as the revs are between 2k and 3k then cruise engages. Can then change gear to get the fuel efficiency. - A6 2008 2.7l Diesel. Hope this helps.

99% of the time it's the combination switch (the column switch assembly that houses the turn signal stalk and the headlight stalk). They're not designed extremely well and are a known failure area on the A4, which I believe shares the stalk with the A6. If it's the stalk, it's about an hour long job yourself to change it out, and the part is about $158 new. You do have to deal with the airbag though (the steering wheel has to come off), so if you're squeamish about this, it may be better to have it done by a shop.
