Bought a used M4
Discussion
Good morning.
Bought a used M4 from my local BMW dealer yesterday.
Two issues that don't seem right and I'd welcome comments of members before discussing with the dealership later this morning;
1. Starting from cold - a very noisy rattle from the rear box of the exhaust for 20 seconds. It sounds like an exhaust issue rather than the engine.
2. The modes for gearbox, engine, suspension and steering (Efficient / Sport and Sport+). When Sport or Sport+ is activated during driving they 'drop out' and revert to efficient.
Can they be chosen short term by just scrolling through the individual options (as per my previous car) or do they have to be saved to M1 or M2?
I appreciate I need to read the Owners Handbook however in the short term Im looking for a quick update.
Many thanks.
