Ok boys thanks for your input. i was only going on what the wifes dad said.

ill get him to find the engine code

[Webby the Bear]

Ps, ill get code reader on it.

been researching. assuming its the 1.9 non-v6 (im sure its not v6). seems like maf is common issue and also n75 valve....  is this the vw term for wastegate? lol

as said will get the engine code asap but thought id ponder. out loud

[Marks DTM Calib]

Don't guess, diagnose.....

Also, as said, it might not have a wastegate 

An N75 is the boost pressure regulator valve

Completely agree mate. though ive never worked on a VW diesel so i was just really pondering out loud to try and get things right in my head. sort of like planning a provisional attack that i can amend

speaking away from this issie itself, why are there so many vac lines?? i thought it was very simple..... exhaust gas spins turbine. this in turn spins compressor. compressed air goes back in to the inlet. and a wastegate (or equivalent) was there to stop over boosting when the turbo ran too fast. i really thought it was that simple 

but as said, ive never dealt with one in real life (hence the pondering lol) so im really keen to get stuck in to this.

Variable vane turbo if its a Pd engine and no wastegate

Isnt PD the really advanced diesel system?

im assuming the one on her dads 2000 passat will be DI with an injector pump?

2000 is right on the change,could be either

1999 was when the first PD's hit shores.

And advanced....er no, it was a compromise setup as VW don't like paying royalties to Bosch for Common Rail. 

As for VW or any other, they all work the same!

The vac pipes will do many things for the likes of swirl flaps (if fitted - multivalve engines only), possibly EGR (is vac operated) and in this case, although not vac operated, the inlet pressure can control the boost (or on the variable vane setups, vac controls the vane position)

[Webby the Bear]

Cheers boys

Will update when i get this engine code

Yup lol

Best thing to do is actually see the car,and take it from there,it may well be something simple and easy to fix

Completely agree mate. He still aint told me engine code. going to chase up now.

[Webby the Bear]

Reset then boys. Here's the pics of hopefully engine code. Is this the 1.9 tdi as suspected?

[serek]

No engine code there
On timing belt cover should be label with code or in boot under carpet
