My A6 keeps flashing a warning symbol on the brakes and telling me 'parking brake auto release fault' and then the traction control light comes on and it warns me that the ESP is off and drive to a garage carefully. but then everything stops and the car works fine, it does it now and again, could there be something seriously wrong or could the computer be going a bit haywire?

Thanks Jon

 

Could just be a problem with a sensor, but you might want to have it checked out anyway. What year is your car? Newer i suspect being that you probably have nav.

 

its 2004, its got the nav n mmi, do you have any idea how much that could set me back, iv only just got the car on friday as well.

 

just bin driving home then and it happened again and this time the engine management light came on as well, and it felt like the power steering had gone, im going to take it back tomorrow, does anyone have any ideas of what it could be so i could tell them.

 

04's were available with MMI? never knew that.

 

its the 04 new shape, but im starting to wish i never bought it, i just hope the garage want be ******** with me and get it fixed

 

Mine does the same thing, but it just started after I spun out down a block doing 50mph...guess I should make an early doctors appt.

 

I had some similar lights going on - also, the cruise control stopped working and the ABS light would remain on. Turned out to be a relatively inexpensive brake switch sensor. Cost less than $100 including installation.

Hope it turns out to be something that simple for you.
