Hello I read the posted by White I think on changing the FPRon my Discovery TD5 very helpful thank you I'd like to add a hint but cant see how to post it in the correct place When trying to get the new FPR in with the new gasket in its correct placeit is a tricky task because you have to hold the body and the gasket and get the bolts in I taped one of the bolts The bottom one I think) in place so that it was just able to hold the gasket in place using masking tape on the outside of the body - the bolt was only a few mm through to hold the gasket but not be in the way This then meant that with one hand I could position the new FPR and also get one of the other bolts started in its hole, then removed the tape on the other one - job done! Hope it helps - it is a hard job,suggest you also claen before removing the old FPR to stop dirt getting in Also Ifound that I had to unscrewboth fuel pipes to get the thing out and newone in and then reconnect the pipes as well as the hoses

Hi all, Thought it might be helpful to record my misfire problem and solution. The 2001 Discovery II TD5, 80k miles, with a fsh started 'misfiring' under load and above about 2,500 RPM. Of course being a diesel misfire is not the correct term - but it ran rough and would not pull, seemed short on power. The problem was only apparent under load, when accelerating hard, or uphill and only when revs got beyond 2,500 or so, although this varied a little between 2,500 and about 2,900. The injector harness has been changed for a new one with improved sealing. No problems starting, idling or driving gently about town or up to about 65mph so long as acceleration is gentle. A dealer check showed no fault codes, although the air flow was a little low so they swapped out a MAF meter, no improvement, so they put the old one back in free ( amazing) After lots of searching on the internet I cam up with a long list and started at with the simplest and cheapest items. Step 1) Checked red plug on ECU, still some oil despite injector harness change, must be residual oil in engine harness, cleaned it out, no improvement Step 2) Checked other end of harness where new injector harness plugs into engine harness, no oil step 3) Removed turbo heat shield and disconnected wastegate actuator rod, found wastegate to be very stiff. It freed up easily with some oil, replaced everything and problem solved - its great to have full power back. It seems as if the wastegate was not opening under heavy load, so boost pressure was geeting too high and so the ECU was shutting down fuelling to protect the engine, hence the rough running and poor performance. My lesson learned is that the misfire did not appear to be the same cylinder as it was more random than that, and it must have been a general lack of fuel for an instant. Hope this helps someone with a similar problem. Rob K
