Old Traveller - did this problem occur when the outside temperature was hot? Just wondering because it seems to be fine today and it is a bit cooler. Having said that it is the first day since filling the tank with Shell V_power, so two changes I suppose make it difficult to see which one has...

Thanks Old Traveller, I was wondering about that. A replacement ECU is very expensive, I saw a "refurbished" one for £600, and I would not guarantee it would be OK. The swap out apparently involves some re-programming of the new unit in order to talk to the EcBM. But I was wondering if a chip...

No, no warning lights, and also no diagnostic codes revealing component failure. That is mostly why I suspect there is nothing serious but it is one of those silly little things that happen to cars when they are 12 years old. It is just so difficult to find. Had cars in the past that would...

It sounds then as if the non return valve will not fix it. This problem usually occurs when driving and not on startup. It was the pump in the tank that was changed. The problem really is that it is so intermittent I could take it to a dealer & they will say "fault not found". If fact, it is...

Great advice - thanks. Will fill up tomorrow with v power * go & buy some pipe. Will report back here when done , probably after a week or so to confirm results. :)

Yes new fuel filter (+ all the others) & I just changed all the oils. But I haven't changed the leak off pipe - what is the significance of this & what does it do? By the way it is just coming up to 120,000 miles. I did wonder about Shell V power, or is there some other fuel additive, and do...

Well it has been checked by the local garage though they are not a LR specialist they work on lots and have done over the years. The initial diagnosis was a fault with the crankshaft sensor, which was the fault code that kept recurring. So this was changed & fault code went away, the fault...

Does anyone know more about this? I was told by a dealer that they often fit a non-LR modification after the fuel pump on the 2.5 diesel to stop fuel surging backwards towards the pump. Some sort of one-way valve. I have intermittent roughness, and occasional cut-out, though most of the time...

sorry delayed reply - it was a dealer, under 3 months warranty. BUT...... now 3 months later and.....same symptoms have started again. Local garage who know P38s said error code definitely point to crankshaft sensor. So changed this but still same problem - where to go next ? :-( :doh:

All fixed. Everything is now working fine. I have also since been through deep water no problems. It was......... A faulty fuel pump !!! Dont ask me how that could also have upset the suspension, but since a new pump was fitted the car has been transformed. Smooth, faster and no other...

rayc, i think the first 2 are ok, but will check the alternator tomorrow - thanks.

Thanks gemsdad, I suppose I hoped the RR would be like my Discovery only with a bit more luxury, seems that's not the case. I think I may trade in for another Discovery. Due to living in a rural area it would probably be more practical. :-(

Can anyone help please. Just had some problems that lasted for 3 days: engine would cutout completely at low revs, also at higher revs when running but kept going (just but with lack of power). During the same time period, the car would sag when stopped, then lift up when started and continue...
