hi can anyone explain what could be at fault, just been on motorway and car runs great no smoke at all had full service. got synergy2 fitted. but as soon as i get into a 30 zone hardly touching the peddle i start to get a lot of blue smoke from the exhaust. it is going in to garage next week but i would like some suggestions from you experts that i could pass on to the garage just in case he cannot come up with anything cheers
