Did you take note of the fault codes or ask for a record of them from the mechanic? Your description does not sound like a compressor related fault. Did you ask what fault finding was undertaken? There’s many examples of intermittent faults at the various linked threads, both here and Disco3, that are fuel pump related whether HP or LP. It could be a sensor too but without some kind of troubleshooting method it’s just guessing.

Hi Guys, I had the same problem with myD3 2009 would drop to bump stops go in limp mode only did this intermittently for over 3 to 4 months. Changed alternator went good for a few more weeks then the same problems. Took it to my landrover guy who put it on his computer where it said 100% electronic brake problem 30% HPFP we changed the hand brake. Went a few more weeks then same deal. Changed the HPFP and now 3 months later and 15000klm later going great. So after going through everything that could possibly cause the problem I would confidently say change the HPFP and and you will have no more problems.
Anyone tried to replace the hpfp themselves? Seems you could save a lot as labour cost is quite high.
Good question. In the last 3 days mine has gone from one error every couple of hundred Ks to 6 or 7 per day, I'll be finding out sooner rather than later.Quote:

I realise it is not something that is easily done. I helped my brother, a truck diesel mechanic put a HPFP in a Nissan Navara.
Lots of traps for young players.
I did the high pressure fuel pump a year ago, no one could tell me if it was going to be the high or low definitively but I took the plunge and almost a year on no issues.
I was having gearbox error restricted performance faults and going to limp mode sometimes not for two months then 6 times in a matter of 10 minutes. It was extremely frustrating but so irregular I managed to drive a caravan to tassie and back just by turning the car off when it happened and back on again.
So so happy to have that issue behind me.
Fyi Yi I got an indie to do it for 3k - Land Rover was going to be 6k but they were going to do both the high and low.
I know Disco WA ( Roger ) done the replacement himself , he's a top bloke I am sure if you sent him a PM he would happily let you know how difficult and what you will or won't need .
i may be having to do mine as I have similar issues , and have purchased the 2 main lines that come off the pump as they are single use only according to the Land Rover manual.

Touch wood, no HPFP issues to date. Reading all of the above, is there any preventative maintenance tips ?
I replace fuel filters every 12 months (roughly every second oil service), check for water in the fue from the bottom of the filter roughly once a month, and check the system for any fault codes regularly.
I always refuel at the same BP and always buy the Premium Diesel. I also use a fuel system cleaner about every 4 refills.
Not sure if there's any more preemptive actions I can do, any advice appreciayed.
Have had one fuel related issue about 2 years ago (injector went out of range), no reoccurrence of that one.
Not keen on spending 2-3k on a new HPFP if there is some relatively simple checks that can be done.
Cheers
