RPS:
I just bought a new Rail pressure sensor on 2.7TD 2007
mine is ref. 55PP1901 MY A and the eBay brand new one is similar 55PP1901 but MY C with a shouldering diameter bit different.
Is there any seal /gasket btw sensor and rail because it's an huge leaking around.
I can't find any instruction on tightening also..

Thanks for your help.

So I bought a new one from EBay...

5WS40209/55PP19-01 including orignal spec. MY A and not MY C

This time the shoulder diameter is fine. There is no leaks. BUT the car can’t start.
“Signal to low”
If I replace the other Spare, it’s working fine except this predictable leaks.

Have you an idea about this code defect ? Is the sensor Wrong or not ?

Thanks

EDIT:
I bought a third one from an traditional dealer and same defect: signal to low.
unfortunatly I presume a polution in the common rail due to this first leaking "ebay" sensor rubber parts could be now inside the rail.

As anybody tried to clean this? the car is ow in a LR workshop and they'll probably charge for sensor, rail and pipes...and maybe more..
