Just got my 2.0 TDI ref sport 140 a Celtic remap by A for AUDI in Clydebank and man what a difference 
Very pleased with the extra power it has now. Only one thing is when you cane it there is a lightish brown smoke coming out the exhaust that I never really saw before the remap. Any way I phoned Celtic direct and their tech guy says it could be EGR or MAF sensor is needing cleaned or changed. I said I hope it wasn't over fuelling and he said no it wouldn't do that.
What do you think guys. The car has done 74k miles and is a 55 plate.
