Hello everyone, I'm afraid that my car seems to have caught some sort of a drivetrain issue and I won't be able to find out exactly what is wrong until next week. 'Till then, it's parked
.
As I was going to work in the morning, at one point I accelerated hard and the engine seemed to start making weird noises. The power delivery wasn't something I was used to. After taking the car to the quick service center, I was advised to take it to the main service (that usually isn't a good sign).
Symptoms thus far are:
- Louder exhaust noise inside cabin
- Subtle rasping noise when above 50kph and 2000RPM
- Weird gearbox shifting (not downshifting like usual)
- Engine vibration is visible when idle and standstill
- At idle, RPM's go up and down (+/- 500 RPM)
- Engine "choked" when I switched from comfort to sport at standstill
- No engine check light, or any warnings from the system
Vehicle Details:
- F20 M135i
- N55 Engine
- Production Date: March 08 2013
- 8 Speed Automatic
Has anyone experienced any of these symptoms? Does anyone know what the possible cause could be? I would appreciate any feedback.
