Range Rover L322 TDV8 Fuel problem - limp mode

[wheeliebin]

Hi

My 2006 L322 TDV8 consistently goes into limp mode after 8-10 miles of normal driving. If I pull over, turn off and restart it is then fine for another 8-10 miles. If I drive very carefully (ie keeping well under 2,000 rpm) it goes much further.

This issue first started after having a fried alternator replaced (on the way back from the garage).

There are two (relevant?) faults reported on my Lynx Evo - P0087-00 (fuel/rail system pressure too low) & P2290-00 (injector control pressure too low).

I have replaced the fuel filter and the fuel lift pump (in tank). I have eliminated it being a blocked breather pipe (by running with the left hand tank cover off !!)

I have ordered a Fuel Rail Pressure Sensor as that seems to be the cheapest thing that could be wrong.

Any ideas what to do next?

This might come across as harsh, it's not mean to.

Take it to a Land Rover specialist and ask them to check it on their computers to get a better idea of potential issues. Just randomly changing things is likley to be a long expensive process.

You're just guessing & hoping that changing the cheapest items will cure the fault - from another site I see you are also thinking it might be the ECU.
Appreciate you've got a Lynx but any reputable LR indys in your area that could give it a look as experience might give an answer?

It has been to three different garages, including a Landrover main dealer and a local indy. Much head scratching and £100s of pounds in labour costs. Was hoping to find someone on here that might have experienced something similar.

The high pressure system has been cleaned out.

Am hoping the fourth 'expert' will have an idea of a way forward tomorrow...

I had an identical fault on a a TD5, there was a 1 way valve on top of the fuel filter, penny's to replace. I don't know if the TDV8 has similar.

Check for cracks in the intake manifold, with those symptoms that would be most likely cause

Hi Chris

Did you get to the bottom of this problem as I have a very similar problem and looking for advice?

[wheeliebin]

So many problems with Range Rovers I forget what caused this specific issue. The solution for me was to find someone who could actually diagnose the problem.

After using three different garages (a Land Rover main dealer, an independent Land Rover garage and a local garage) I finally discovered Electro Diesel in Exeter. Its not often you find trust worthy experts who actually know what they are talking about, willing to take the time to explain a problem and charge reasonable rates. They fixed this and several issues on the RR that replaced it. Have recommended them to several people since who were all as impressed as I was.
