I can find on tis how to access the turbo boost etcc...so..will start to dismantle what i can to reach it...it does show a heat shield....which looks a bit diff..but....i shall do what i can within my capabilities...car will be off road a few days i think..but kids are off so it doesnt matter too much..will let you all know how i get on..

MO4 .... been looking around in the Tdi website and found this ... this hopefully will give you some good pointers as to what your problem might be:

wow..thanks bleeno.. :ph34r:

[Smilge]

wow..thanks bleeno.. :ph34r:

 

i keep seeing n75 valves, intercooler pipes, relay 109, pancake valve .... havent got a clue what they do but someone might on this site Maz.....

I'm still reading it all at the mo..very good info on there.

Turbo VNT mechanism sticking. This only applies to vehicles with a VNT-15 turbocharger ... most A4-chassis models including all A4-chassis models sold in North America, and all 110hp models (A3 or A4 chassis) sold elsewhere. (DON'T READ THIS if your car has a GT15 or K03 turbocharger because they operate in a COMPLETELY different manner.) Locate the diaphragm housing which operates the VNT mechanism (has a single hose going to it, extreme rear of engine compartment, buried down near the bottom right rear of the engine, hose connection faces STRAIGHT DOWN). Locate (by feel with a finger) the linkage rod which points straight up out the center of that diaphragm housing. While feeling this rod, have someone start the engine, and note whether the linkage rod moves - it should. Upon stopping the engine, the linkage rod should move back after a few seconds. If the linkage rod does not operate as described, get a vacuum tester (any auto parts store) and apply vacuum to the VNT diaphragm to see if you can get it to move. If it's seized up, there's your problem. NOTE: To prevent this from happening, DON'T BABY THE VEHICLE when you are driving it, and consider recalibrating the EGR system to reduce the amount of soot build-up in the exhaust.

 

 

How does this sound,,is this the part i can see in the pics?

It seems like the most likley culprit is the vacuum hoses. They after all are the simplest and the cheapest thing to check and or replace. They may be difficult to get at but they have to be discounted as a cause before you go looking at or pulling out and replacing anything. Your symptoms we cured temporarily by replacing the pipe that had come off - that pipe controls the turbo vanes - check them all!!

Now this i found intersting..under types of TDI.

 

 

1.9 litre 4-cylinder 115hp "PD" - again similar to the A4-type engine but with the "pump-nozzle" injection system. Although the peak power is only slightly more than the 110, maximum torque is much higher and the engine has lower exhaust emissions. VW intends to gradually replace the 110hp models with this engine. Not available in North America, reportedly because the exhaust emission controls used on this engine cannot be used with fuels containing greater than 50 parts per million of sulfur, whereas at this writing (1999) fuels in North America can have as much as 500 parts per million.

 

 

Models with this engine have badges with a silver "T" and red "DI".

 

 

The injection system is the "pump-nozzle" type, and the turbocharger is a variable-vane type. The lack of the injection pump mounted on the front of the engine is the obvious visual difference.

Can someone please show me where all the vacuum hoses are please?

[tim-spam]

Many of them are behind the silver plate you are trying to remove, one goes to the turbo, and another goes to the spherical vacuum reservoir - you will be able to see most of the rest to the left of, and disappearing behind that silver plate.

[mumof4]

But how do i get that silver plate off....thats the thing i need to do..

You need to undo them "screw thingy's" you asked about earlier... They are cleverly disguised as nuts that can be undone by hand
