[mention]Overboost [/mention] Good on you to notice the slight elevation in temps not waiting for the dial to swing to red although did you reprogram your temp indicator to actually work and did it show hot to alert you to check temps?
Or do you have a full time temp display?

I do have my temp gauge buffer reprogrammed to 85C-95C instead of the factory 75C-115C buffer. I would have never noticed it as the temps would only reach 103 sitting in traffic or a long traffic signal. +1 for hex code modification on the cluster temp gauge.
I replaced the pump, thermostat, expansion tank and a few hoses that seemed less than new. I used all Genuine BMW parts on everything knowing it is the way it came from the factory. I had originally replaced the water pump with the Saleri as preventative maintenance and chose to save some money. It could have cost me an engine.
