Chav Posted November 10, 2007 Report Share Posted November 10, 2007 Not sure if this has been posted.... But I've had this fault for ages: Brake warning comes on at startup and then occasionally when driving. Flashes a few times then shuts up again. Anyway, there's a known issue with a certain part, and they can replace the bit with a new one. (That's my teccie description. Apparently the loom goes close to something that gets hot - so they've insulated it more etc too) Had this done yesterday, and it seems fine now - no brake warnings!

UBM Posted November 11, 2007 Report Share Posted November 11, 2007 Had mine done a few months ago too - not seen it since! Link to comment Share on other sites More sharing options...
Sparky Posted November 11, 2007 Report Share Posted November 11, 2007 I didn't think you went fast enough to need brakes, UBM? Link to comment Share on other sites More sharing options...
Nelson_R32 Posted November 11, 2007 Report Share Posted November 11, 2007 Sounds like low brake fluid to me (sometimes even parking on a kerb can set it off) or a faulty Brake level sensor. Link to comment Share on other sites More sharing options...
Sparky Posted November 11, 2007 Report Share Posted November 11, 2007 More often it's a battery problem. Brake system is first on the circuit. Link to comment Share on other sites More sharing options...
kite Posted November 12, 2007 Report Share Posted November 12, 2007 had this done on my B6. they moved some of the looms that are around the brake master cylinder. Well thats what they told me Link to comment Share on other sites More sharing options...

Nelson_R32 Posted November 15, 2007 Report Share Posted November 15, 2007 Apparently the problem only applies to V6/V8 engines and it requires fitting a new relay somewhere in the wiring system. Link to comment Share on other sites More sharing options...
UBM Posted November 15, 2007 Report Share Posted November 15, 2007 You're wrong Nelson. Some of the early 2.0TDI's, like mine, had this issue. I can tell you the recall number if I can find it! It involved putting a relay somewhere on the system as the main headlight switch has never been the same since it was done! I'll find the numbers Link to comment Share on other sites More sharing options...
Nelson_R32 Posted November 15, 2007 Report Share Posted November 15, 2007 Don't worry I've got the numbers But it clearly states 'on bigger engined cars (V6 and V8)' but it's clearly not limited to them. Whats up with the Headlight switch? Link to comment Share on other sites More sharing options...
Guest RichA Posted November 16, 2007 Report Share Posted November 16, 2007 I think this might have started happening to me. I've seen it once and the wife's also seen it too today. - What is the general consensus on what the problem is? - Is it likely to be dangerous (i.e. brakes not working ) or just annoying? - is this going to be costly ( ) Many thanks, Rich PS It's a 2004 (B6) 1.8T Avant.

Chav Posted November 16, 2007 Author Report Share Posted November 16, 2007 Hi mate, I dont believe the brakes will actually fail - The two causes we know of are 1) insufficient battery charge causes brake warning (as its the most sensitive system) 2) a sensor/relay gives false warnings due to getting hot I had the warning lots of times without brake failure, but obviously its wise to get it checked out asap! Since they changed the part, not had any brake warnings! The part was free for me as car under warranty. Not sure if it applies to B6 though, give them a call though!

kite Posted November 17, 2007 Report Share Posted November 17, 2007 I used to get the warning on first start on a cold morning. The dealer told me he just re-routed a cable when mine was fixed ! Link to comment Share on other sites More sharing options...
DanG Posted March 7, 2008 Report Share Posted March 7, 2008 Update for those who are interested. I have been getting the Red Brake warning flashing on start up when the car has sat overnight and even all day outside recently, and it has been to the dealer twice now. They have apparently identified the issue, but the 'part' or changed wiring in the brake fluid reservoir is on back order.. So presumably this is happening a lot? It was mentioned that this is for larger engines, but I have a 2.0T which is affected. I am slightly puzzled though, the car definately takes longer to start these days, and turns over 8 or 9 times before it fires. It is due its 30k service in about a month. I presume that they have checked the voltage / battery.... its worse on cold days too. But who knows. I guess I will be able to tell when the part actually arrives. Oh, they also use brillo pads to clean it each time, only provided a loaner once and and both times have not hoovered the trunk. Little things....
