Thanks guys for the input. I will get it scanned ASAP. I will also start a search on the topics that you have mentioned so I will have a better understanding of how the parts functions. It helps me to learn if I do so.

Powers1 - would the water temp sensor also affect the way the heater warms up. This is my first BMW and I have not had it long (1st Winter). If it was not for the heated seats I would have frozen before x interior warmed up. Just curious if that may be a related symptom of the water temp sensor. ???

Lukaso - your English is fine thanks for the help, but what is supl. zyl 5-8?

thanks again,
