Engine started drove about 300 yards on acceleration had the amber engine light illuminate followed by engine getting lumpy and going into limp mode. Would not clear fault so RAC called, he undid cables/visually inspected all fuel system components, drained the fuel filter, fuel from it was spotless, he passed some air through the filter again no dirt etc. All re-assmebled and now works!!!!! Other symptom it was slow to start on occasions and sometimes it would start immediatly, again it is starting fine now. Fault codes were P0087/88 Fuel Rail System Pressure to low/high. Test Values: 224DT-TD4 (car is SD4) 2.2L 110 (150) 118 (150) He spoke to a clolleage who was ex-landrover and he suggests it it the high presssure fuel pump at fault.

The RAC policy is to delete codes on completion of repair. So no fault codes are presently in the vehicle. (2013 SD4 Dynamic) and after a test run today all appears to be working fine.?????

So now I appear to have no faults, (unless indicated in figures below) do I place in Dealer for inspection or just change the fuel filter?? and keep my fingers crossed. It is under warranty but wont cover a fuel filter and only cover about 35% of Land Rover main dealer labour costs, would pay 100% for any parts though.

I took some icarsoft readings at start up and then idle after run as follows. First figure on start up, second at idle post run.

Fuel pressure relief control valve duty cycle 22.35% 20.39%
Fuel Rail Pressure 43.91mpa 29.49mpa
Fuel Rail Pressure desired 43.65mpa 29.97mpa
Fuel Rail Tem Sensor Voltage 2.71 2.01

Also at idle post run:

Fuel Temp 33
Fuel Volume Control Valve Current measured: 1.33A
Fuel Volume Control Valve Duty Cycle 40%

If you cannot be sure the diesel filter has been serviced correctly and as the car to you is not old to you I would be asking the supplier to fit you a filter PDQ FOC as you have had more than one problem. Had they carried out any sort of pre delivery checks or just washed it ! FL2 MY10 TD4 GS traded in at 2 years

Thanks Yorky Bob, good point I will have a trawl through the service history and see when the filter should off been changed. i know it main dealer FSH up until 35,000 then another at 41,000 (ind) andf then at 49,000 by the dealership that sold me the vehicle. And yep 2nd breakdown since I got the car!!! Two in 5 weeks, feel like I am sorting out the previous owners minor issues.

the fuel may not be dirty but the filter could be gunged up,its quite common for fuel filter problems to throw up fuel pressure fault codes.if the vehicle is not in limp mode but the engine management light is on,the rac can leave the codes or you can photo his results on his lap top.it not rac policy to delete codes ,in fact some manufacturers insist they don't, for warranty work.

Thanks Sid, vehicle did go into limp mode with engine amber light on. I asked for the codes to be left in but RAC said they had to be cleared but emailed a screenshot of the codes to me.

Trawled through the service history the fuel filter was replaced 11 months/8000 miles ago. So this is leading me to think that may not be the issue.

Oooo you suspicious Yorkshire man

I worked at big main dealers over 40 years ago !

It not a easy filter to get at and others on here have found them not to have been changed as per the schedule due to either laziness or corporate theft. FL2 MY10 TD4 GS traded in at 2 years

Well car went into the local Landrover Garage today, he has inspected the car and measured the pressure being delivered from the fuel filter, he says the pressure is borderline and recommended changing the filter. So for fault investigation and new filter £184.00!!!!

Needless to say I will be contacting the garage I purchased the car from to see if they wish to donate to this repair. Expecting to be fobbed off, but we will see

Well did the new fuel filter cure the fault ??? That is the big problem unless you know & trust the garage which does your services god only knows what actually does get changed.

Hi Jack, the fault has not re-appeared since the RAC removed the fuel filter and put it back in about 5 days ago. A pressure test by the garage today said the output pressure from the fuel filter was borderline so it needed replacing. So they replaced it with a genuine Land Rover one and only time will tell if the fault appears again in the near future

Incidently anyone know how often the fuel filter should be re-newed or is it just when a fault occurs?

Read your service schedule information as supplied with your car. Why on earth would you not  FL2 MY10 TD4 GS traded in at 2 years

Fuel filter should be changed every B service every 30,000 miles, it’s best to stick to a genuine Land Rover filter as I have read a Mann fuel filter can give you problems.
