brake pad warning light

teednab-el

ok I was driving to a filling station this evening and the "brake pads worn" warning light flashed up on my ECU display followed by a warning siren. The message permanantely stayed there until I reached the filling station. When I started up engine after refilling, the message did not pop up on my ecu display anymore. I did ECU system check and no warning symbols or problems were detected by the ECU. Why would the "brake pads worn" symbol flash up in one instance and not appear anymore after that. I have almost 83k up on my car and all the brake pads were replaced at 80k.

Car is an 2000 Audi A4 1.9tdi.

Did you brake hard or brake while turning when the light came on first?

If they were only replaced 3k ago, i'd just leave it and if it comes on again take it to a garage.

Maybe you have a dodgy sensor? Not something I heard of before as the sensor is made into the brake pad and obviously replaced with the pad.

Are they OEM pads? If so, go back to the mechanic and have them replaced if necessary. If you did the job yourself, maybe you need to get a replacment pads under warranty. You shouldn't be seeing this after 3k miles.

there could be a split in the wire and if you turned the two wires crossed which then flashed the light on your dash happened before on the fathers car

what you can do yourself is jack car up take each wheel of one at a time and have a wee look at the pads if they look bad bring it to a garage to get changed

things like brake warning lights comin on is somethin i wouldn leave to see if it happins again unless a mechainc has cheked the car and said leave it till it comes on again

hope this helps

I was driving on a straight stretch of road when the warning light came on. I was running low on fuel and I thought it was that first until I actually saw the symbol.

I got all pads replaced by my mechanic on my last service of the car at 80k. I agree I thought seeing that warning light before 3k miles after having them replaced with new ones was unusual.

I didnt hit one on that stretch of road but Ive hit a good few in the last 2 months with the state of some of the roads Ive had to travel on.

sometimes if you hit a pot hole it can dislodge the sender on the brakes
best bet would be get a mechanic to have a look at it
