help!!parking brake failuire light comes on when driving

[beolight]

parking brake failure appearing whilst driving
new style 2005 a6

a little bit disconcerting to say the least

anybody else experienced this, if yes what steps did they take to resolve it

reported on first service but was fobbed off with brake fluid been low and needed to be topped up now 3 weeks after service it has popped up again 3 times

getting worried now as i live on a hill

Being less then 3 years old, the car is still under manufacturer's warranty.
make them sort it out.
Don't let them fob you off.
Speak to the service manager and the dealership manager if required.

Hello beolight,on the first 4f a6 there was a software update for the light coming on and the brake not always realeasing when pulling away.Faults are normally stored,did you get a copy of 5051/52 diagnostic log with your service sheet.Also check if the switch light is flashing at the same time.The software update referance number is T.P.l 2012608/3 If the dealer isnt aware of this solution.Hope this covers your fault description.Regards Jon

thanks for reply guys

just to add to the body of knowledge here

a6 was in with dealer today and the computer logged 2 incidents of the fault thankfully

it needs to be hooked up to a diagonostic machine to further illuminate which apperently is very expensive and my dealer has requested a loan of the machine from audi ireland

the mechanics thoughts on it are that it is a loose /faulty connection along ther line that is preventing infomation been relayed on the gateway and if the info is out of synch and not relayed to computer instantly it will trigger the fault

the parking brake itself is fine so at least now i can park safely without the aid of a concrete block behind the wheel

hopefully they will get the diagnostic machine soon and i will further update the forum
