Dieselers, With so many postings on ACC troubles, I thought I'd offer some suggestion on how I deal with ACC problems on my 123s. The ACCs on both of my cars misbehave but problems can be minimized with a few simple procedures:
1. Always select Defrost mode first after you start the car. Always. Whenever the ACC is turned off or the car is turned off you must start over in Def mode. After 3 or 4 seconds in Def, then select the desired mode. You have to do this even in the middle of summer, and yes it can get hot for a minute or so. But if you don't initialize the system in Def, the ACC will misbehave. 2. Never cycle the buttons quickly. If you do, it can switch into the 'ACC From Hell' mode where it sticks in Defrost mode with the blower on high and full heat and ignores all inputs. It can stay in this mode for weeks. The heat can crack the windshield Or it might simply go stupid. Always be very deliberate and wait a few seconds between each button selection. 3. What to do if it sticks in ACC From Hell mode: Select Defrost, then let it cook for 15-20 minutes while driving (Ugh!). It must get real hot inside the car. Then select the desired temp and mode. If nothing happens, repeat the process, except longer. This ALWAYS works on my cars, eventually. With a litte TLC the old ACCs will do their job reliably. Try these tips and see if it doesn't help.
