Its 2008/2009 E93 with 325i.

It has only 40k km and bad luck...

Friend that got it borrowed for weekend managed to crash it (not totaled). After repairing it was fine for like half year and now after winter strange things happened.

While we were driving the light turned on and said go to the service.Got it to the service they did something to it and sorted it somehow (didn't said anything much about it, just "regular" problem).

And now the problem is back. Yellow engine light on, the whole car at low speeds (10-25km/h) is shaking, when we stop the vibration increases. Acceleration is messed up badly the revs raise slowly (not like before).

Question is : What could be wrong with car ? (engine sound is even strange, like 1 or 2 cylinders might not be working). Maybe you have some contacts that would be able to say something about it ? Because we have no clue what to do with it. Yes, we can drive to the service and pay few k so get it sorted for few months, but this ridiculous.

Thanks for response

sounds like a misfire. Take it back to service.

Most commonly it's a bad coil. It sounds like the shop just replaced one coil. If one coil fails, usually, the others will soon fail. You can keep replacing one at a time or you can replace all of them.

definately sounds like a bad engine coil. same thing happened to me recently and it was a bad coil. you can either have a diagnostics ran to see which coil it is or just start replacing them until you find the right one(s).
