my 2011 TDV8 moved this moring about 10 feet and it has broke down outside the house the AA turned up 3 Hours later although i did tell them that it was in the middle of the road. I have the following codes come up and would really appreciate any help
P0088-22(27) FUEL RAIL/SYSTEM PRESSURE TO HIGH. GERNERAL SIGNAL FAILURE / SIGNALAMPLITUDE & GT: MAXIMUM
P0087
P0195
The other two were brought up on the AA code reader.
Many thanks in advance

You might want to read through my post below about a problem I had and resolved. My car is a 2010 3.6 TDV8, so there may be differences in how the fuel rail pressure is regulated.

Essentially on the 3.6, there is a fuel rail pressure regulator. This releases excess fuel into the fuel feed line. But my fuel filter had never been replaced and I think wasn’t allowing the pressure to release sufficiently. I replaced the fuel filter and it has been completely fine since.

This might not be your problem, but it has to be worth a try. If it works, it’s a cheap, quick and easy solution.

Good luck. Current: 2010 Range Rover L322

Brilliant I would try that but my wife (the enlightened one) had reminded me that we have a warranty on the car and after checking it out the fuel pump and most of the gubbins are covered and the AA will be collecting this morning and I still have my sanity and clean hands 🙌. Thanks for your help I will keep you updated 👍

Just a quick update Steve the garage had the car for the weekend but found no fault which cost me half a tank of fuel and £210. Couple of weeks later I experienced the same fault but this time the AA patrol man had said that he had come across this problem once before and said it’s the auxiliary fuel pump. He gave it a bash it sprung into life I got it home changed the pump and BOB’s your auntie it’s been fine since. Thanks for your advice
