Overheating problems and check engine light on 2012 BMW X5: experience with repairs wanted

Hi everyone, I have a problem with my 2012 BMW X5. It shows overheating and the check engine light is also on. Current mileage is 198123 km. I suspect it's the coolant thermostat, but after my last bad experience with the mechanic I'm a little worried. Has anyone had similar problems and can share their experiences with repairs? Thanks a lot!

Hey buddy, had a similar problem with my 2015 BMW X3 at the garage the other day. The overheating indicator and the check engine light came on almost at the same time. It was actually the coolant thermostat, but it was also about replacing the coolant sensor. It was quite stressful, but definitely no reason to panic. Try reading out the fault memory, maybe that will clarify things. Hope that helps!

Hey, thanks for your tip! Would you happen to remember how much you put down for the repair? Has anything else come up with your X3 since then? A car like that can always have surprises in store!

Hey, no problem, always happy to help! So, I paid €170 to repair the damage to the wiring harness. You know, since then the malfunction of the coolant thermostat has been fixed and my X3 is running like clockwork again! Yes, it's true, the old speedsters can sometimes really cause surprises, but so far nothing else has been wrong. Keep your fingers crossed that your X5 will be just as uncomplicated!

Thank you very much for your quick and helpful reply. 170 actually sounds quite fair, that's what I would have expected. Good to know that your X3 is running well after the repair. I'll take mine straight to the garage and hope it works without any surprises. Your advice was very helpful! Thanks again and I hope your X3 continues to run well!
