Hi, thanks for the quick reply. My mileage is 197512 km and the last service was recently, everything looked good. I will have to take your advice and probably take it to the garage. I just hope the repair won't be too expensive.

Hey, you're welcome! It's good to hear that your car has been serviced recently. But yes, these unexpected problems keep popping up. It sounds sensible to take it to the garage. So with my X3, yes it was a faulty cable connection, but it's hard to say if it's the same with the X5. Fortunately the repair on mine wasn't too expensive! I'll keep my fingers crossed that your problem can be solved easily and not too expensively. If you have any more questions, just get in touch here. Good luck!

Hey, thanks for the encouraging words. I realize that every car has its own peculiarities and the problem with my X5 could be a different one. But it's good to know that it doesn't have to cost a fortune. I will definitely keep your experience in mind. Thanks again for your help and advice. I think I have everything I need now! I'll definitely be in touch if I have any more questions. Take care!

The exhaust smells funny, not diesel, what could it be?

Hello, do you have the same problems as the questioner? Or is there a topic here in the community where your question would fit even better?

Hi, I once had a similar problem with my BMW X3 (gasoline, 2010). My car expertise is pretty low, but I have learned how to handle such things. I took my car to the garage, there they found out that the cable connection was faulty. It cost me 155 euros to fix the problem. Could you give me a few more details about your car? Maybe then I can help you even better.
