Hi Guys.

Been having a problem with my Range Rover for a few weeks.

If I sart the car and leave it idling in Park for about 30 seconds to a minute, then select Drive or Reverse, the Rangey stalls???

If I stop in a road and move from Drive to Reverse, the Rangey stalls??? Sometimes it's a little different, when slowing right down to pull into a parking space say, it drops right down on the revs and almost stalls then the revs come back up and away she goes. Sometimes it just stalls???

Ive had the codes read, and the two main ones were 0136 Fuel Quantity Actuator and 0035 MPS Signal error??? Nobody seems to know what these codes are. Somebody in the trade has said that they had to have their ECU read as if it were a BMW X5. This apparently allowed him to get "P" codes when he had issues with his..... Does this sound right???

Any help would be most appreciated as I slammed into the Managing Directors car the other day when it stalled out (No power stearing or brakes :( )

I hope to god someone can help. This is doing my head in........

Thanks Guys

Rob

Any good code reader should be able to give you the p codes, I know mine does for the motor.
What are you using to get the codes out of it?

It is indeed a '99' 2.5 Diesel. Does that make a big difference??? I hope so, could really do with an answer.

Not sure about the codes, but the fuel quality sensor code points towards a M52 engined p38 as the petrol versions don't have. The fuel quality sensor unit is located above the fuel filter in the engine bay. This sensor should have put up a dash warning though, even briefly. Did you see anything at all?

To be honest, you really should get a specialist to read the codes using Land Rover's T4 or Autologic. The codes you've listed don't really make any sense in their numerical form, but T4 would show you a specific issue related to a LR vehicle.

However, from the description, I'd guess you've got something in the fuel tank which shouldn't be there. Could you change the fuel filter and empty out the contents in a container to check for contamination?

Hi there.

Sometimes when I lift my foot off the accelorater, the dash warning light comes on for a split second. There's no response from the pedal when this happens??

I'll take the filter off when I can get outside and take a look. This really does my head in when it happens.

Cheers

Right, just had a look at the fuel filter. Nothing un-toward in there.

However, to one of the cables on the sesor at the top, there is a single wire, this runs to a small box that says Allisport on it. The larger cable on the other end of the box runs to another connection near the engine!!

Does this mean it's chipped???

Could this be causing me the problem?? If so could i just remove this box??

Sorry for all the questions, but this is my daily driver and i'm desperate to get it sorted..

Cheers lads.

Could well be a case of a re-map and another issue causing the problems. Why not try it without as you've said?

Bit of confusion here and I'm the one drinking the wine ! The fuel quantity actuator fault gets logged when either the injector pump is worn out or a dodgy plug in box is used.There is a slight chance of there being air in the fuel,but starting would almost certainly be an issue too.
The fault gets logged when the feedback to the ecu from the crank sensor,needle lift sensor and driver demand,(Throttle pedal) dont add up.Basically the engine is not making progress that the ecu expects to see given the sensor inputs.

So it's a fuel QUANTITY sensor, not quality as I've somehow misread... :roll:

That all makes sense now.
