ElectricEclipse Posted 8 hours ago Share Posted 8 hours ago There is an intermittent problem with my X1 2.0i; after about 5 miles, it starts to overheat and flash warning lights to stop. On certain days, it will occur; after a few weeks, it will begin anew. I brought it to a nearby repair shop, but they couldn't diagnose the issue, even though they could feel the engine's heat. Reached out to AC. The warning was visible, but the diagnostics returned no results. The engine heat sensors are functioning properly, and there is no cooling system leak. The AA advised that I consult a BMW expert, so I did just that. I was able to keep the automobile for a day, just like the AA. I drove it for miles without any issues. Uh-oh, huh-huh.

NAVITEL Posted 8 hours ago Share Posted 8 hours ago Perhaps the thermostat is stuck. Please tell me the year and the mileage. Quote Link to comment Share on other sites More sharing options...

QuirkyPixel Posted 8 hours ago Share Posted 8 hours ago If it's b48, the water pump inside of them is mechanical and can be controlled in part by a vacuum actuator. Since it only happens sometimes and no errors have been generated, my first instinct would be to inspect the vacuum actuator and the performance of the pressure converter. If there are no obvious problems, I would then replace the pump because, similar to how VW pumps stick inside, the mechanism could be jamming.
