Auto Climate Control, Version code
 

Having problems with my 1999 R129 ACC. It blows super hot in the auto 72 degree setting. The in car temp sensor checks out OK. I want to verify the version code, on line 42 I get 11 , I believe it should be 03 on line 42. I reprogramed the version code to 03 but when I recheck it is still 11. Is 03 the correct version code for the '99 R129?

yes that is the correct code...03...are you storing that code by holding the "EC" button for 1-2 seconds.

Stupid me, did not hit the EC button 03 is in but temp now reads metric????
