Intermittent Power Loss On Tdi Galaxy

[fullmot]

please can any one help am pulling my hair out here.

bought w reg galaxy tdi 130 bhp.

loses power quite often when under load cannot go over 2500 revs its like the turbo is no longer there .

when i switch engine off and on problem is sorted back up to full power.

so far i have replaced the m. a. f with no effect.

air filter changed ...improved power but no change to problem.

was told it was fuel filter ...changed that........no change

have checked all pipes for splits and all are fine

have been told it could be throttle position sensor but is

Sounds like the vanes are sticking in your VNT (Variable Nozzle Turbocharger) and it's tripping into limp-home mode (switching off and on again clears it).

There are numerous references to this in the forum if you search.

Sorry for a silly question but, what does the T-MAP sensor look like and where is it located (2000 90BHP tdi)? My Haynes manual is of no use at all! I have tried replacing the MAF sensor and have replaced the vaccum hoses with silicone hoses and tried cleaning the turbo and still it goes into limp mode. Thanks in advance, Dave.

My first thought is that you should get the error codes read. Use Ford as a last resort but see if someone on this site who lives near can help.

 

Th Tmap sensor is (I think) fitted into the return pipe from the intercooler which comes up from under the radiator and up the front of the engine then over the top to the inlet manifold vie the infamous EGR valve. Look about half way down for a wire going to a device fitted in the side of the pipe. When you get it out it will probably be covered in a messy gunk. There is probably a thin tube connection somewhere near it which feeds the pressure back to a sensor on the ECU.
