Hi i have a bmw 525d automatic and the car seems to jerk and lose power every so often and then a parking light failure sign comes up when the lights are fine, any ideas thanks!!

SOURCE: Oil light comes on, car loses all power...

havent seen this problem on any yet. make sure who ever changed the oil used 5W20 the hemis are very picky

SOURCE: Transmission Light and Braking problem

hello . did the dealer scan the vehicle anyway , if the light was on it should have a history code safe in memory and they should check for it . it does not matter if the light when out by it self ,it just means that the fault its not present ,(it sounds like a bad mass meter its a fuel manegement sensor that when it goes bad the transmision does not know the force created by the engine and therefore it cant shift properly)

SOURCE: jerking and losing power

Probably bad ignition system which can be anything from a failing coil pack,ignition wires or cracked spark plugs. Look closely for signs of missing by looking for cracks in plugs,bad plug wires or a white/green crusty chalk build up on the coil
