Question about Volkswagen Cars & Trucks
Now if i knew what you meant by blew ?? then i might have a idea --most turbo faults are caused by dirty oil and changing the engine oil every 5000miles with a filter every third oil change will stop this problem .The other problem is the turbine vanes breaking off or being damaged by grit where the air filter is missing or a pipe loose or split allowing the thing to suck in unfiltered air but i do know someone with one of these and he sold it in the end and bought a transit as the turbo gave up quite often ,but without taking the turbo apart then i couldnt tell you why they are failing but i do know he kept a small hand held diagnostic machine in the cab and when it went into limp mode he cleared the codes and off he went again .Seem to remember as well the waste gate operating piston playing up i think a rubber tube perished so it didnt open and the increase in pressure as the engine revved up caused the thing to go into limp mode as too much pressure was being generated ,the rubber tube goes from the pressure side of the turbo to the piston its about 4cms long so as the air pressure builds up it this pressure pushes the piston which opens the waste gate which is a little flap on the exhaust side of the turbo into the exhaust manifold so when it opens it allows the exhaust gas pressure to go straight down the exhaust pipe releaving pressure on the turbo vanes .If the pressure in the inlet side goes too high then a sensor will put the engine into limp mode .Hope you understand this technical jargon ?

Testimonial: "thank you for your suggestions, in saying the turbo blew,i mean just driving along and the turbo stopped working, loss of power, plumes of grey smoke from the exhaust. I did have a total new engine fitted say three before all this turbo problems started."

SOURCE: limp home mode
You need to scan for engine trouble codes. Most parts stores will do this for free, and tell you what they mean and make recommendations on what to do. The 'limp mode' kicks in to prevent damage to the vehicle when the computer gets data that something is wrong.. When you shut it off, it's temporarily reset, but then the cars computer is signaling there is still a problem, and it goes back into limp mode. If you have any questions after getting the codes 'read' , post questions and code #;s here for help. Good luck.
