Hi,
Hust wondering if anyone can help me here, i have a Range Rover TD6 that has a intermittant Fuel injection problem.
Some times is runs rough as though its running on 4 cylinders and the fuel injection error is displayed, i had the fault codes read : p3505 glow system
p1195 rail pressure control valve
p1190 rail pressure control
I replaced the secondary fuel pump 8 months ago, i have just replaced the pressure valve as was advised this was the problem. i thought not as its the sensor that has detected low pressure and something has caused this.
its a intermittant fault that no one so far has been able to help with.
some times from cold start it runs fine and twice now its smoked like a house on fire ! it also has run fine for some journeys.
i was thinking its a injector or two leaking into the cylinders and causing pressure irregularities.
what sort of tests can be done for this?
any ideas ?
thanks

Hi there, did you ever find the cure to your problem? Mine sounds exactly the same? Was you able to change the fuel pressure control valve yourself? Thanks

Hi, the fuel regulator ( In the end of the fuel rail ) is very easy to change, just remove the pollen filter casing to gain access.

The fault was a faulty fuel injection wiring harness, only buy a brand new one or a known working one as the wires go brittle and they go high resistance...
Easy job to do and Land rover only charged me £45 for a new one.
Hope this helps

Thanks for that sounds like it's a pretty common fault now I looked it up, thanks for pointing me in the right direction, all makes sense now, just need to see if I can get the loom for £45 still?? 😁😁 cheers!!
