MY23 Coolant Expansion Tank

grimluster · 06-04-2023, 09:55 AM

Does anyone know if the coolant expansion tank is still an issue for MY23 M5C's?

I just took my car in for the 1200 mile break in and service said that there were no recalls or anything like that for my car.

Is there any way to confirm?

I got mine in Jan '23 and just went through the 10k service and had no issues. I checked in between the break-in and the 10k and looked good.

There's an updated version of that tank so I don't think it an issue anymore.
