ashok540 0 Report post Posted August 19, 2008 Any one know why my cruise control suddenly stopped working? I use it quite regularly, set at 60kmh to make sure I dont overspeed, it was working fine and suddenly the cuise light went off on the dash. Now I cant get it to turn on at all!

It could be one of many faults causing that Ashok. Needs to be scanned and checked. Anything else not working, or do you have any other warning lights on at the moment ???

Anything else not working, or do you have any other warning lights on at the moment ???My a/c switching not switching on when car is started after a long time is the only other problem. I will give you a call tomorrow and bring my car over. Quote Share this post Link to post Share on other sites

I will give you a call tomorrow and bring my car over. Scan and check faults= (1) Brake light switch faulty causing cruise control not to work (2) Voltage drop inside ignition switch causing intermittent fault in climate air control unit Clear all fault codes, DME, ABS, EGS, Kombi (Combi). Road test and recheck All done Edited August 21, 2008 by botanymotorworx Quote Share this post Link to post Share on other sites

Road test and recheck All done Thanks Glenn, everything working fine including my earlier problem of A/C swithing off automatically! Guess that was also due to the voltage drop.
