Climate Control R230/2003
Since some time I have a curious problem with the automatic climate control unit. With selector on "automatic" even after a short drive the system starts to heat excesively and the vent-fans turn at full power. The heat is then well above the selected temperature on the climate control unit. Only after about 20min driving time the system re-regulates itself to normal levels without any manipulation from the driver.
Anybody had the same occurence/problems? Is it eventually the temp-sensor?
Suggestions? Solutions? Thank you in advance for your help and advises.

It seems that I have found the problem. The car was driven very seldom
during the winter season. The 2nd battery in the trunk got de-charged.
(Warning indication on the display). It seems that the climate control
automatic system does it's own "reset" and thereafter re-adjust itself.
As I'm driving now more regular with the car and I do not have this problem
any longer. Therefore it is recommended to have the 2nd trunk battery on a
permanent charger-unit when parked for more then one week.

Your car should be able to take a week off with out the rear battery going dead. Sounds like a new battery is in order.
I put the battery tenders on when I know the car is going to sit for a month or more just to be safe.
My 05 had the rear battery go bad after 2 years in service and was replaced under warranty.
