I have had car for a year (used CPO)- it runs great.
It has 45Kmi, never any probs. Just noticed that at approx 3000 to 4000 rpm (if running DS mode or Manual mode) if feel a slight hesitation as the car continues to accelerate. It really is minor as the car performs extremely well.
It is still under full warranty. Should I have them check something specific?
Thanks in advance.
Thanks for responding. Does not seem like transmission, just minor engine bog. Maybe I am too picky, I don't often drive in sports mode or manual - but it is fun sometimes to push a little. Car is awsome even after a year and 17K miles!
Might be worth getting the petrol pump looked at, but only if its doing it when your pushing a bit harder which is y Im guessing its in Sports mode, had the same problem on a 93 525 and was the fuel pump. But obviously your ones a lot newer and alot less k's.
Happens on 330s sometimes as well. Can be the fuel pump, especially if you let the tank go under 1/4 tank often (weakness in these 3.0 M54s). Also, since you are under warranty, check with the dealer for any firmware updates.
