Hi, i'm new to this and am in need of some experienced knowledge.
My Passat started going into the classic limp mode and the local VW dealer told me it was the EGR valve and a leaking tandem pump. I changed these to find the issue still existed so I renewed all the vacuum pipes and replaced the N75 and cleaned the MAF sensor, still no power and going limp so bit the bullet and changed the turbo to no avail. I eventually discovered that the catalytic converter had spun sideways constricting the exhaust, so I cut it out and replaced the original turbo. Eurika, it went like a rocket but now when it warms up a little I get a blast of white smoke when I pull away from stationary and once the temperature gets to 90 it stops smoking but looses power and goes into limp again under load and the temperature drops by 10 degrees while driving in limp mode. I am really confused now and the temperature takes a long time to get to normal.
Any ideas gratefully received. Thanks
