Fabia Vrs..lost all boost help?

[EuanGtTdi]

garage checked it today and came back a code something like 17664 and the code is turbo charger boost pressure valve not reached i think it was, saying it could be the coolent temp sensor is away as they give mixed singals or something

this make any sense?

That code brings up this

That would only relate to possible poor MPG and difficulty starting the engine.  I've not heard of a faulty temp sensor throwing a car into limp mode

i was reading up on the fault code on the skodas and when they are meant to go the coolent temp sensor they give mixed singals and brings up fault codes for egr valve, manifold pressure, manifold temp sonsor, charge pressure sensor and sure someting to maybe do with n75 valve not sure on that one tho

all getting bit confussing now

If you grab an Innotec turbo cleaning kit and give that a go ASAP it might cure your problem.  If not you may eventually be looking at new turbo time.......

Ouch mate    I feel your pain 

Not the first idea I'm afraid mate.  R-Tech fitted my new turbo. 

Where you getting it from?  Make sure its setup tidy as mine came back and there was sod all boost from idle until 2000rpm.  There's a stop / adjuster screw which wasn't set correctly.  I never had this rectified though and sold the car as it was.  Just something you need to be aware of    Past 2000rpm it was an animal and pulled harder than before
