ABS & ASR warning lights plus cruise control not working

You will need to have the codes retrieved from your ABS System's Computer. The ABS and ASR are really the same Computer but different software, one stops slipping during braking and the other stops slipping during acceleration. The Cruise Control uses some of the same speed sensors so ti would follow that it too would not work when the ABS and ASR are not working. here are some shops: http://repairpal.com/mercedes-benz-repair-in-jacksonville-florida

you need to scan the ABS module to confirm the problem, but it is most likely a defective stop lamp switch. the code will show as a "plausibility" issue, but it is very common on MB's. you also may not have any brake lights, so you should fix this. any good MB specialty shop will stock this switch, confirm and clear the codes for about $165. if the shop does not stock this switch, you're at the wrong shop.
