Suspension lowers, limp mode, codes P2290/87-00 FIXED!
Well set out on a day trip to Dorset from Suffolk, for a family Christening. 150 miles from home car suddenly bings, suspension lowers and limp mode kicks in.
Pulled over and restarted engine but as soon as you accelerate away it happens again. Managed to drive the final 30 miles, sorry to anyone stuck behind me on the A30!
2 codes present; P117D-00 fuel volume regulator exceeded maximum control limit and P0191-23 fuel rail pressure sensor range/performance signal stays low.
Plugged in iid tool and the fuel rail press is N/A, the other fuel pressure reading is present and rises with engine revs.
Does this sound like a rail pressure sensor failure? I have pulled the plug from the sensor and refitted it, but no help.
Looks like the AA will be taking us home
Any thoughts welcome. Thanks.Simon.

OK, the car is back home. I have reset the faults and went for a drive, after about 20 Meters it all kicks off, however watching more carefully I notice that the first warning is the amber DSC light followed by the amber brake system warning followed by the suspension lowering. There is no engine management light.
the codes are:

I am now wondering if it's the brake pedal switch.
Any thoughts welcome.Simon.

Lowering suspension, limp mode etc. are all cascade symptoms of many possible scenarios, including steering angle sensor problems, speed sensor issues etc. etc. etc.
In your case however, I think I'd be looking at changing the fuel filter as you have a number of fault codes pointing towards that.
TBH, you may need to replace a few things before you get to the bottom of it but as fuel filters are relatively cheap, I'd start there before moving on to other possible causes like brake switches and steering angle sensors. Mods:
Front Fogs + Halos
FBH Remote Control
The 1st Ever RRS Modded Grill
Garmin Nuvi + D4 Surround + Reversing Camera.
D4 Steering Wheel.
Rear Boot Spoiler.
Twin Brake Lights.
Wing Mirror Indicator Repeaters.
Long Roof Rails

Thank you very much for your reply I very much appreciate the opinions of people who have been around Land Rovers longer than me.
I have decided to change the fuel filter, as the 90000 mile service is now due and it's nearly 20000 miles since it was last changed.
I have seen several posts mentioning that it's normal for the fuel rail press to be n/a, but also some giving values.
What is the situation with a 08 model non dpf car?Simon.

I honestly don't know.
Change the fuel filter, see if the situation improves. Mods:

I have now changed the fuel filter. The symptoms are just the same, but the fault codes are slightly different.
Here are three sets of codes from the iid tool, the first one is after the filter change, car not driven, the 2nd and third are after resetting the faults and driving the car. It goes into limp mode as soon as you put it under any load. The last test drive I managed about a mile on level ground, not above 30 mph, but as soon as I came to a hill it went limp!

I am going to buy a test gauge and check the fuel pressure from the lift pump next.
Any other ideas welcome Simon.

This sounds like what mine is doing currently. It's in with a specialist now through warranty so I'm told.
If I hear anything I'll post up, to me I get the impression it's HPFP but I could be wrong.
You need to check the fuel pressure from the LPFP with the valve at the rear of the engine.

Since your suspension is lowering i suspect you have a problem with the Suspension/Height sensors.
Please check them with your iid Tool. I had a bad connection. Your car then thinks: "something is not right" and stops everything and prevents you from driving to fast (Limp Mode).
It does not show up when you read the signal. You must log the signal in order to see this.
In this picture here you can see the bad signal.

Thank you for the replies.
I have ordered and am currently waiting for a fuel press. gauge and a current reader, so that I can test the low pressure fuel supply.
Next time I have the car running I will check the suspension signal log.
With the faults cleared I am getting a fuel pressure from the iid of 24190 kPa at idle and 40530 kPa at 2000 rpm. Does that second figure look a bit low?Simon.

IMHO: the low pressure fuel fault can be there because of the limp mode.
The Limp mode "kills" your fuel. Your Car says "Fuel pressure fault".
The same is with the Height sensor. It causes the suspension to lower.
You reset the car and it rises again.
You do this 5 times and you will also have a "Compressor high temperature fault."
You do this 10 times and you will have alle the same faults you get when the battery is low.
Check the suspension first.
Good luck!

Thanks guys. I was thinking that my fuel pressure was a bit low at 2000rpm.
Dutch, just reset and went for a drive this was the log.
