Hello i have a audi a8 3.0 tdi quattro 2005 i just had the battery and the alternator changed on it and the throttle body.when i put the ignition on is comes up with the error "battery manegement level" and when it starts on the first spin the engine choke's then it starts or it just spins for 6-8 times before it starts.
Another thing is that sometimes when it starts for about 1 minute it takes out a white-blue smoke the car drives verry good.
Please is there anyone that can help me...i already spent £1000 to change what ever this mechanics have thought is wrong now i just need to be sure...thank you
