Skoda Octavia1.9 TDI turbo boost problem

[skoda08]

Have just been told skoda will extend good will past warranty and supply new turbo Still have to pay labour but will certainly save me lots of expense. Talked to dealer about it possibly being solenoid or some other simple problem but they are saying it's definitely turbo. Will have to wait and see. Hopefully new turbo will solve the problem and get me back on the road.

Great outcome, hope all goes well for you

the vacuum actuator diaphragm is probably cactus and most of the time cannot be bought seperately which means whole turbo has to be replaced

What a joke though....

Turbochargers are so darned reliable, good quality OEM ones dont just go bang (and if they do they usually fill the intake with bits of alloy). So your right of course - this is probably stuck vanes or a bad diaphragm.... but just seems so silly to me that they dont sell the actuator separately through the dealer parts network.

You can certainly get them aftermarket, its just a matter of getting the right mechanic to find it and do the work for you (more trouble than its workth for most people i suppose). I would hazard a guess, though, that the process of replacing and then adjusting the correct preload on the actuator is "too hard" for the modern dealership, and hence the replacement of the whole unit (where the preload is adjusted by the factory - hence the dealer can't screw it up (no offense buzuki!)).

Ahh well.

No its not to hard for us. There is other turbo actuators we replace seperately. And we have to set them up. Some are probably full replacement due to the rods acutally being very difficult to get to adjust.
