the ASR light of my 94 E320 wagon came on already twice when i was going 80mph with the cruise control on. it doesn't happen inmediately. it happens around 15 to 25 minutes after i set the cruise control. if i restart the engine and don't use the cruise control everything is fine. any ideas? i'd like to take it to my local mechanic but i'd like to sound a little bit familiar before i present myself. any ideas on what's going on? is it something a DIY person could fix? is it expensive to fix? etc.
thanks in advance,
