HI... last week or so my car is pretty un drivable. i have a 55 plate audi a6 2.4 auto s line. now its been driving fine then all of sudden the engine cuts and i get a check light that beeps and says BRAKES(!)
THEN when i press the check button on dash it saps (p) brake malfunction.

this only happens when i turn round a right bend. very odd. then all i do is start up agin and its ok again until i try make a right turn again.

please help

 

These cars have a build in immobilizer that kicks in should something go wrong with an axle or CV joint. Check the cv joint boots and see if one of them is loosing a lot of grease. Its probably just an axle problem, simple cheap fix.
