Having a bit of a nightmare with the A4 at the moment, ill explain...
came home form work in the car, parked up then about an hour later went back out in it, about 1 mile into this journey the car just lost power and the brakes came on by themselves an slowed the car down to about 5mph, all of a sudden im able to accelerate again but 2-3 second later the brakes come on again, I had to turn around and drive the car home like this at varying speeds between 5-20 mph with the brakes going on and off really repeatedly! car was making some horrible noises at this point everytime it was applying the brake by itself, possibly just the wheels locking up on the road I don't know?...
got home and felt the brake discs, front drivers side was red hot..
the orange triangle with the exclamation mark on the dash was flashing but this has always been a problem on this audi for years, its either always on or its off, it doesn't usually flash when you put the brakes on.
anyway, I tested the car this morning an its working fine again, (orange triangle light is still on as per usual) but im gunna have to get it in the garage to be looked at as I don't want that happening when im doing 70mph!!
has anyone heard of this happening before? google search didn't find anyone with the exact problem, any advice from anyone on what it might be before I take it to the garage?
