Filter: Under hood, driver side, front side of strut tower, rear of battery, mounted on fender in fuel line
Pump: inside fuel tank but accessible from inside the car--see procedure below from autozone.com.
1993-99 Cabrio, Golf, and Jetta
Remove the negative battery cable.
Raise and safely support the vehicle.
Relieve the fuel system pressure.
Remove the rear seat and the access cover.
Disconnect the wiring and hoses.
Remove the fuel lines from the pump.
On 1993-99 Golf, Jetta and Cabrio vehicles, unscrew the fuel pump retaining ring.
On all other models, remove the mounting bolts and the fuel pump.
Carefully lift out the pump and gauge sending unit assembly.
apart from the obvious choice of checking the air supply pipes to the the turbo and then from turbo to inlet manifold ,the only other course is the electronic sensors and the computer ,This would have to be either a dealer or a Bosch agent ,and the chances are the agent would only send it to the Bosch diesel specialist.These new models have a lot of complicated software involved and i wouldnt evan like to give any sort of answer without a visual inspection myself to try to diagnose the problem
well i have never done it myself. but its going to be alot of hassle.
its not the same as sticking a turbo on a petrol
1 you need a manifold which will suit it
2 for best results you need an exhaust to match
3 you will need to replace the fuel pump. to match the size of your engine (preffrably take the turbo and the fuelpump from the turbo version.
4just as well stick a new timing belt on while the fuel pump is off
then you need to tap into the oil as turbos need a constant oil feed. and that might require drilling and tapping into the block.
this is only an educated guess but im sure its pretty standard in fitting a turbo to a non turbo viehical.
Fill your fuel filter all the way up and take precaution not to get any air into pump. Try this several times. Once you get air into some pumps it can be very hard to bleed it off. There should be some way to bleed. Look on pump for bleeder.
sure it is possible, but it won't just be a mechanical solution, you will have to change all related systems to the turbo units.
the attachment of the turbo will be fairly easy... then...:
you will need to rework the exhaust add oil supply to the turbo, a return, which means new or modified oil pan turbo EFI system capable of feeding the turbo, may need new fuel pump as well turbo computer (or computer hack) to understand forced induction, which may also need some sensor changes non turbo pistons may not be sufficiently strong ... ...
