Hi guys, I know this is an old thread but if anyone else has the check vsc problem this will help. Buy a cheap code reader from ebay, put wynns egr cleaner into half a tank of diesel plug the code reader in and clear the fault and rev the car until it stops stuttering then take it a drive doing high revs then sit in 3rd gear @ 3000rpm for as long as you feel its necessary I usually do 10 miles like that. It genuinley works.
