Before abt 3 months i changed the secondary pump as i had the engine cutting off problems above certain nr of revs.
Before a weeks while i was in a high way car bong and "injectors fault" appeared in dash.
Got in a parking area and after 2min stoppage restarted the car with no problem.
Strange was that at that time car also lost clock/screen settings date/etc.
When i returned back i changed the diesel filter,just in case,as i did not replace it when i changed the pump.
But since then car mainly revs only upto 4k- from time to time it gives me the pleasure to exceed them- and then is cutting out but without any bong/dash msg while if i let the revs to fall below 4k and till i will reach them again it normally responds.
Car has not any starting problems either when is cold or hot but i am with impression that in general runs harsher.
Can it be a defective secondary pump ?????? since the one i bought is still under guarantee

Any ideas please

Have you done any work on your injectors?

Try a leak test to see if any of them are not working as they should. .

AKIS, you may wanna try putting 1/2 liter of 2T oil in a full tank of diesel. it lubricates injectors and pumps. First time I used

2T in my car i felt immediate difference for better.

Thanks guys.Any idea if any bosch leak off test kit will be ok or i need a specific one???
2t oil in tank had tried it in past with minor quantity however but at least me saw not any difference

Injectors leak test has been done and not any problem appeared.Engine still cut off at arnd 4k and recovering if i l let accelerator pedal fr few seconds.I am with opinion that this happens only when engine in normal temp with temp gauge at 12o'clock.
This is irrespective whether tank is full or half or whatever while when engine cut off not any msg appears in dash panel.
Any ideas please??????????????????

I had the same as you and it was the pump. Even though I had done less than a months driving with the new one ! Fitted another and all back to normal.

Thanks mercs600.This is what i am also suspecting.I just bought a cheaper one for testing.If problem will be solved then i will return the "PIERBURG"back order they replace it as still under guarantee

Best rgrds

I found this the other day while searching around trying to get some help with my TD6 injector issue, have you had it on any diagnostic kit? The thread below is long but his problem was a wiring issue that only manifested itself when car was at normal temperature.
It sounds like you have already solved it with the pump but if not this may help.

Thanks guys.Problem solved.I replaced the already replaced secondary pump and all in order now.
Obviously the first pump i bought although was a Pierburg was a defective one.
Now try to obtain the refund for the Pierburg pump which still under guarantee.

Many thanks for yr assistance.
