okay, i posted a thread about a potential turbo problem, however this now might not b the problem. car went for a service n MOT today, everything was fine part from usual tyre tread getting low and discs nearly worn.... but i still have smoke coming from my exhaust...however what i thought was blue smoke, seems to be grey smoke as you would get on a cold morning. they brought it to my attention that there was alot of pressure in my water tank than normal when u took the lid off under pressure, it steemed like a bitch which may they reckon may indicate a gasket problem. if you read my previous thread to this you will know the smoke still comes out when decelerating and accelerating in the early gears. the smoke often doesnt come straight away either, sometimes 20 mins into the journey or sometimes not long after start up. these problem lead me to believe it were a turbo problem until now....can anyone or any specialist give me anymore of an idea before i take it in for diagnostics n pay a fortune (just seems like i got one problem after another! least it past its m.o.t oh and to top it off, when they put it onto the ramps they popped my front lower spoiler off at one side, great!!!
