What would you do?

Hi Luke,
really sorry that this issue remains unresolved for you. As we've previously discussed via PM's, we had our HPFP replaced following our 2011 (MY12) D4 2.7TDV6 throwing this same fault code, toward the end several time a day, while we traveled the Great Central Road. On each occasion turning the ignition on and off reset the system and we were able to continue, albeit for unknown distances and or times. Changing the fuel filter (clogged, presumably by a load of by dirty fuel), cleaning out fuel tank (small but apparently not unreasonable amounts of crud), testing Low Pressure Fuel Pumps (flow rate tested OK, twice - once in Alice Springs, once back in Adelaide), we bit the bullet and had our HPFP replaced on the advice of the indi where the car is serviced (PCB Landrover Specialist - Adelaide).

As we've discussed, if the issues is as infrequent as yours seems to be maybe it's in the category of 'wait and see'. Interestingly the proprietor of PCB suggested that in his experience the fault starts slowly and builds. Maybe it's worth giving PCB a call to have a discussion.

Just to give you an update, we've now traveled approx 7,500km since replacing the HPFP (and associated drive belts) without any re-occurrence of the fault. Makes me feel comfortable that the fault was either in the pump or one of the embedded sensors.

All the best mate.

OK I've spoken to our mechanic about this issue and he has told me on a lot of occasions they have resolved the issue with replacing the low pressure fuel pump in the tank, stating that it could be failing and can't supply the HPFP with enough fuel causing the car to go into limp mode, yes I did see your's has been tested.

Thanks all. But no, my fuel pump has not been tested and it wasn’t offered..

I was initially told by the indie to come back when it happens. I also went to LR last week and they said wait until it happens again and then bring it in ASAP afterwards.

I will ask again

The testing suggested in the Disco3 link I posted can be done anytime to try and confirm LPFP health but it would not be in the WSM. Pump testing wouldn't help with finding a sensor problem. I'd be showing the suggested process to the independent. The dealer may not be interested to work to non-WSM guidelines.

We have the same issue by the way, our indie suggested to replace the LPFP mainly because of other vehicles with this issue after changing the HPFP it didn't solving the issue and it's a cheaper option first up, I just hope it works.

Quick update.

Another weekend away and I got limp mode just once (6 hours of caravan towing and some beach driving but this happened at 60km hr on a dead flat straight road) - I assumed this would be the same error but today when I checked the codes I got the following error instead:

P2290 - injector control pressure too low. (NOT the P0087 error I normally get)

As earlier in the post:
I checked the MAP sensor - all clean, now.
I checked the tail lights, all LED's are working - just to rule out brake light switch I have read about
I checked the LPFP schrader valve - showing 7 PSI on idle.

Now I'm not sure if this is a new issue or related to the same one, if related why would it change?!

I have a long trip from sydney to tassie and great ocean road coming up in 3 weeks.. feeling very anxious about whether I will make it or not which is the last thing you want from your car.

Certainly related & same issue Luke. This is the classic/common progression when it's a LPFP or HPFP issue.
A quick search here and in Disco3 will provide plenty of detail.
It is getting more likely to let you down unless fixed, all the signs are there ....

Scott

Agreed, hence my nerves.

I just wish it would fail now (while in sydney) and we can fix the exact issue rather than the risk of spending thousands on the LPFP only to spend even more on the HPFP or vice versa.

Once I fix the other issue I will book it into LR for this one.

Hi Luke, I am having symptoms which are identical. (MY08 D3 TDV6 - ~150K KM) I now randomly get either P2290 or P0087.

I changed the fuel filter and it seemed to make a big difference in the power and responsiveness of the engine - for a little while - probably only about 1 week before it started getting sluggish again and the error codes started coming back with limp mode. Now back to getting it on average about 1 time a day.

I am certainly interested if you have any updates on your situation?

Cheers, Matt.

Maybe try changing the filter again, if it made a difference and then went to crap again it would be logical to think there is heaps of crap in the tank and its blocking the flow of the filter again. If that is the case it I would remove the tank, clean it and replace the LP pump.
