I have a a 2006 Audi A4.

Last night on my way home my head lamps turned off. When they turned off my dash lights when out, and my heater/climate control turned off. Fortunately they turned back on after a moment and I was able to make it home. However, it did happen again while driving. I also noticed that the cruise control is no longer working.

It seems to have all quit working together. In the morning I know I used cruise control to get to my location, I know I had the Auto setting used for my climate control. The only thing I'm not 100% sure about is the lights, as there was daylight.

Thanks in advance!

 

RIP my dear sweet A4.

 

Do your brights work when you pull the lever back? I'm leaning towards the ignition switch...not hard to do if that is indeed your issue....

Do the turn signals work? Wipers?

 

Brights, no. I thought the turn signals worked, but I don't remember.

Car has been in the shop for a week now.

They replaced the battery, and said the comfort control module needs to be replaced.

 

A week? Audi dealer or Audi independent mechanic?

It is possible it's the CCM.....if you had the codes, it would be easier to make a guess.

But if it does get wet (as a lot of them do) generally, windows, key fob, sunroof are the first to go, but it is possible.

Could also be a relay under driver's side dash by footwell. Climate control has it's own module, but is connected to the CCM.

CCMs are expensive. Hope it works for you, let us know the outcome.
