Hello there !
I just broke a 2nd time my coolant tank on my E46. The temperature are normal for M52, runing a 102°C and 87 at higher RPM/charge )
Im using my car near Paris, so i often in the traffic, and my coolant getting high so often, so i wanna know if i can change the curent map for the next one with only 87°C


Maybe by limiting the pressure with lower coolant temperature can improve the problem with my tank ?
