TD5 Power Loss
drum:
Definite improved after a trip to wakefield this afternoon. Couldn't really give it a good run, but managed to go down at 60/70 all the way, which I couldn't have done earlier in the week. problem came back though on the way back (didn't stop in wakey long), so it could well be related to heat now. I think the Air Flow filter has helped things though.
Hopefully the kit should arrive tomorrow and shed some light on it.
LOFTY:
From when i had my problems, i found you cant use standard ODB reader on the earlier TD5 ECU, as Land Rover made the set up differant to the europian spec i believe.

The one I got doesn't appear to talk either despite listing a 2004 TD5 Defender in its compatability lists. :cry:
I'm awaiting a response from technical support, but I really can't see that happening before tuesday now.

--- Quote from: "Porny" ---Crankshaft Position (CKP) Sensor is too close to the flywheel or the drive plate. This is most likely to occur when the engine warm or hot.
In this case you need to plug it into a computer and look for 'High-speed crank sync lost fault' - cure is to fit a spacer.

The problem does appear to be worse when the engine has warmed up, so I figured I'd have a play. As a test (and obviously not a long term fix) I put a washer below the lug the securing bolt goes through. Result - little if any difference, possibly slightly worse. So I tried 2 washers, Result - won't even start. Don't think it proves anything really, other than it'll take more than a washer to fix it :D
I'll see what the outcome is for Diagnostic test tomorrow, I suspect it might be going back.

Anybody know about this from another forum
--- Quote ---Web rover may be onto something, while in the UK last month I needed a new clutch master cylinder, mine was starting to go (seal was beggining to leak)and as I had a long drive home i decided to get it changed over there as its covered by the warranty anyway, so I got the dealer in Lincoln to do the job. They dis-connected the battery to do the job, but obviously didnt plug it into the test book afterwards as it developed a flat spot just in the mid range and felt slightly down on power on the top end, I didnt notice this straight away as I was concentrating or noticing the difference the clutch master cylinder had made. However I did notice eventually and by then thought something else had decided to start to go wrong, so into my dealer here I went, I needed to put in the warranty claim anyway.
The mechanic and I were going over the car, checking all the oil levels, replaced the fan belt as it had become perished slightly and was squeeling when cold (only in the uk tho, not cold enough here) and looking for any problems visually that may be apparent, anyway none found, then the mechanic asked if the battery had been dis-connected, I then realised that it had been dis-connected in the uk, so we plugged her into the testbook and he went through the injector calibration process as I had a feeling the flat spot was down to fuelling, ie stuffed injector, hey presto perfect again, flatspots gone
I think that its outrageous that a dealer trained mechanic (specially in the uk, you expect a more proffessional approach tbh) would not realise he needed to do after dis-connecting the battery ! no doubt because they like to charge 75 quid an hour to put it on the testbook. If i were paranoid I would think that was a money making exercise as I was bound to come back at some point to find out what was wrong and chances are by then I wouldnt put the blame on them and maybe even have to pay for a tune up !!!
Here in portugal the dealer doenst mind if you go and watch the service being done, in fact now I've me the mechanics I sort of become an assistant the piece of mind I get from knowing that all was done properly and all trim put back properly afterwards is fantastic."

I had the battery of a few weeks ago (probably around when this started) to clean and service the starter motor.
