How can I reset the check engine light on my BMW XM?

I recently bought a used BMW XM and the check engine light came on. I'm not sure what the problem is, but I want to see if I can reset it before taking it to a mechanic. Any advice?

You can try disconnecting the negative terminal of your car battery for a few minutes and then reconnecting it. This can sometimes reset the check engine light. Another option is to purchase an OBD-II scanner, which can read and reset engine error codes. Just make sure to address the root cause of the issue after resetting the light.

I've found that driving the car for at least 50 miles after filling up the gas tank can sometimes turn off the check engine light. It could be a loose gas cap causing the issue. If the light stays on, it's best to have it checked by a professional.

There are also some DIY methods, such as disconnecting and reconnecting the car's negative battery cable while holding the brake pedal, that some BMW owners have had success with. However, I would recommend consulting with a mechanic before attempting any non-conventional methods.
