Overheating problems with a 2010 BMW 3 Series gasoline engine

Hey, I had a similar problem with my 2012 BMW 5 series diesel. In my case, it was damage to the wiring harness that caused the indicator light to come on. I had it fixed in the garage and it only cost me €120.

Hey, thanks for the answer. My BMW petrol 3 Series already has a decent 224851 kilometers on the clock. Like your 3 Series, it's already got a few years under its belt. I also notice that it mainly overheats when I go on longer journeys. Does this also apply to your car? And if it's the thermostat, do you know how much it might cost to replace it? Every penny is important at the moment, thank you!

Hey, glad you reached out to the community. Well, I actually had a similar problem with my old 2009 BMW 3 series gasoline engine, and yes, for me it was the thermostat. Your symptoms were exactly like mine. My indicator light was on and my car was also constantly overheating - especially on long journeys, just like yours. I then went to my regular garage and the guys there replaced it in less than two hours. It cost me around €270 - that was the part plus labor. I hope this helps you and you find a solution!
