Solved my problem,

I 'll just post the solution quick, for other diesel drivers who might ever experience this problem.

Turns out there were 3 burnt out wires underneath the back seat touching the car's body. This caused the fuel send unit in the tank to behave abnormal.

Second thing I found was a wire touching an aluminum air hose in the front. Underneath the fuel filter unit. The insulation had molten away and one wire was making contact, appearentely touching the metal tube when the engine-block shifted slightly during left turns.

After redoing the wiring all problems went away. Car drives perfectly again.
How my mechanic did not see this is a mystery to me. I can only tell what else he wont be seeing, me.

 

Hi Azethechamp!

Do you have any picture from this wires?
My 98 XjTdi it´s makes me crazy...

Hi, I have a similar problem in my 2001 XJ. I changed 3 Cps and 01 cable arnes, but no better, the engine gives power cuts, OBDII P0727 and P1727 codes. If someone help me I regard, thanks.

 

check all your wires.
The plastic isolation wears out due to age. Electrical wires touching mass causes the ecu to freak out cutting out the engine.

So far I had 3 major problems with my vehicle caused by this issue.

 

Hi Azethechamp;

Problem solved!!

The connection between CPS and A/C Switch
Pressure High (C120) .This cable is shorted, when on AC begins to fail.


Thanks You.

 

Hello to all people with VM Diesel.

I´ve the same problem that someone on this thread, my car doesn´t want to go up 2000rpm above. Three n1 inyectors tried, all of them with the good ohm value, two MAP sensors, from cars that are working properly, no error code in the dashboard. 4 different mechanics and no one knows what´s happening, and now I´m poor

Could it be the CPS?

Thanks a lot, I´m searching around the world for info about it and ussually seems to be the n1 inyector, but nor for me.

Regards!

Same here, trying to find someone with a DRB3 in the hopes clearing the codes will solve the issue.. anyone know of a way to wipe codes without one?
