I've had some issues with my e46 330i, it has lost a considerable amount of power, it's gotten very slow and really doesn't accelerate like it used to. It has also been burnig a considerable amount of oil, approx. 1 L every 5000 km. Is there anyone who has an idea of what could be worng with the car? The car has got 100000 km on it but i dont think this should be an issue, being that i always took it to service to the dealer's shop and i had never had this problem, and it has never overheated.
