A Land Rover main dealer have come to the conclusion via the fault codes given on the Land Rover diagnosis machine , (p2290-00), that my high pressure fuel pump, needs to be replaced. They have not done any other tests other than the diagnostics.... Following that main dealer diagnostics test, the following day I the went an small Indy for another diagnostics test and they came up with the same error code, but this time they showed me the read out which read "injector control pressure too low" (see photo attached).

Can somebody please advice me if the code (p2290-00) is specific to the High Pressure Fuel Pump, or how LR came to that conclusion. They Indy just told me to start with changing just the fuel filter etc... I don't want to pay 2000 odd pounds for a HPP to discover it was a fuel filter, or low pressure pump, or something equally as cheap-
Help will be very much appreciated,

From that code alone, you cannot say that the HPFP is definitely at fault.

It is indeed more likely to be a blocked fuel filter or low pressure pump.

I imagine it has something to do with the price tag...

Hi,...Thanks for your input. Yes I'm no expert, but I was a bit suspicious. I'm planning to go back and ask them how they got to that conclusion. I have just been emailed the diagnostics print out (attached), maybe that means something to you as it also shows other codes.. I live in Spain, so its in Spanish, but perhaps the codes mean something to you..Do you by chance know of anything else that code might relate to that I could challenge them on...Id like to sound at least a bit knowledgeable if you could kindly advise me.

I would think the filter and LP pump the most likely (and significantly cheaper) culprits and would always start there. An electrical fault is possible too.

What symptoms are you getting?

Here are your pics:


As it happens, I was just about to post what is shown in your second picture:


This intrigues me:

Thanks for your input "lost for words"... A year ago an intercooler pipe split, resulting in the RRS kicking out black smoke and huge loss of power. Changed the intercooler pipe and all was fixed.. A year on, same symptoms but on a more minor scale. Car will travel a casual pace without issue, but if I turn up a slight incline and push the pedal a bit harder, car will hesitate, splutter and go into limp mode. Once I turn engine off and on again all is working normally (unless I apply anything more than casual power). Trouble is, down here in Spain all the garages seem to think foreigners are rich, so we always need to treed with caution on what they recommend. In your opinion, is there any way their diagnosis of the HPP could be accurate at this stage, just by using diagnostics machine?

Sounds like the classic symptoms of a blocked filter/LP pump failing. Do you know when the fuel filter was last changed? The HPFP could be the cause, but the low pressure side should be ruled out first.  Visiting from DISCO3.CO.UK

Its all a bit strange to be honest... I took it to an Indy last week for a fuel filter change, but when I later collected the car the guy told me he was NOT going to charge me for the filter change, as it was "nothing". But he told me I must take the car to LR to get it checked out for the power problem.. I thought it strange that he wouldn't charge me, plus he also said I get discount if I use his name there. All enough to raise my suspicious eyebrow!!!... (or perhaps he just figured what he looses on the filter, he gains at LR when he earns commission for the referral, who knows?).... Anyhow, I'm having the fuel filter checked on Monday, so I will know more then. I'm aware that my battery is on its last legs though, it went flat some weeks ago when I left the interior light and radio on for just two hours or so... it couldn't be related to that could it?

It's probably not related to the battery - that is probably the cause of the U-codes though (they can be ignored unless you're getting symptoms).

That sounds as suspicious as anything to me! They stick a duff filter in, and get a referral fee from the dealer, you pay them for the HPFP pump to be replaced, then, as promised you're problem is solved - because they removed the duff filter. They get a nice wedge from it, and you think you're getting a discounted rate. Conspiracy theory or reality? Hmm... Visiting from DISCO3.CO.UK

Yes it all smells a bit. Anyhow, I've just ordered a LPFP off eBay and once it makes it way down here Ill fit it and see if it does the job. Allow me to thank you for you excellent input today, it has absolutely been of help to me. First time user, very happy with the forum. Ill update you when I get some results. BR

Always glad to be able to help.  Visiting from DISCO3.CO.UK

Hello "Lost for Words".... you were kind enough to offer me some advice last week, so at the risk of boring you I thought Id update you to the probable end of my story... As follows, .... my car was not performing well at all, so I took it to a local garage. I asked the owner to change The fuel filter as I suspected The problem might be fuel related so I thought I'd start with the cheapest possible problem, so I hoped that perhaps the fuel filter may be blocked.. the garage owner ordered a new filter for my car and booked my car in for the following day. The following day I left my car with him, several hours later he phoned me to come and collect my car, when I arrived he told me that much was wrong with my car and I need to take it to Land Rover to get it fixed. I thanked him and asked him how much I owed him for the new fuel filter, to which he replied "no charge it's nothing", But I know those fuel filters are £60 so I tried to insist that I pay him. But he insisted that I didn't need to pay him, so I said that was very decent of him but I was a bit suspicious.

I then booked my car into the main Land Rover dealership here in Marbella, and to cut a long story short I returned six hours later to be told that there was a long list of things that needed doing to repair the car. The total bill they presented to me would amount to €7000 in total. They told me that the high-pressure fuel pump needs replacing to fix the engine problem and my cooling system had two leaks in it and items needed replacing, and also several items on my front suspension needed replacing. I asked them had they checked other things in the fuel system rather than just choosing the most expensive and they said that they had checked everything. I also asked if they had checked the fuel filter in case it was blocked and they said they had and it was fine.

To try to cut a very long story short, I smelt a rat, and I took my car to a small independent garage owned by an English mechanic. I specifically asked him to check if the fuel filter had been replaced and I also asked him to check if there's a problem with the cooling system, and to check the suspension as well...... But I did not tell him anything about what Land Rover had told me, he knew nothing of what I've been told previously.... The end result was he confirmed the fuel filter had NOT been changed and in fact he said the filter was about as old as the car, seven years old. When I test drove the car home I discovered the new filter change had fixed the engine problem completely.

He had also checked the coolant system, and said there is absolutely nothing wrong with the cooling system. He also inspected the suspension which Land Rover said needed a lot of work, but he changed just a €60 Bush, and that pretty much did the job. All in all, what Land Rover tried to charge me €7000 for in fact I got done for €300. It is quite possible I think that Land Rover and the guy in the previous garage have some kind of scam going on.... I am seriously considering writing to Land Rover head office or contacting the local newspaper, absolutely shocking!!!

So I thank you for your input, your comments backed up my suspicions and encouraged me to continue to go with my hunch.... Shocking story!

A great concern indeed. Sadly, you're far from the first to have had an incorrect and rather expensive diagnosis from a LR dealer, though this is a pretty extreme case.
