White smoke

[as92lv]

What could be wrong, I bought cupra 1.8t drove home around 100 miles, nu issues at all , then I stopped at home and suddenly there was loads of white smoke coming out of exhaust! And was boost leak and boost was shaking, found out there's was atmospheric dump valve fitted, changed that one, no smoke and no boost leak, just boost shaking after 3500rpm. What could it be? Thanks

Yeh what do you mean? Like when you put your foot down the cars shaking?

Boost is dropping from 0.6 bar to 0.2 then again 0.6 and like that till 7000k revs. Cheers

Could be the N75 valve mate thats going, if you tell me the letter at the end of the number on the valve I'll see if I can get you one today, I've just sold the last of them I had.
