Hello I've recently been getting a clooud of white smoke from my car after i turn it off to get it out of limp mode. My car is a 1.9tdi awx I've had a intermittent limp mode problem for a few month now which I think is down to my boost pipes and inter cooler been shot so I've just been turning the car off and back on and it goes away. I am currently in the process of having new custom hard pipes made and have my front mount fitted just not plumbed in yet. I have only had this recent problem since it was serviced a week and a half ago could it be linked I have also had suspicions on maybe Incorrect oil but I doubt as I use an Audi VW specialists which leaves me with my other suspicion turbo seals. Could anyone give a bit of help on my situation it would be greatly appreciated one more thing when I've had faults read it says something about boost sensor or something could this be a culprit also.
