Taken him to the garden centre, now waiting on recovery again.
Bit awkward and lumpy again first start but we'd had 2 deep frosted mornings so assumed it was that.
Fuel pressure is good unlike last time, so this is some sort of ignition issue. Often fires for a second or two but then dies at 500 to 1000rpm and won't catch again, sometimes won't fire at all. Doesn't respond to throttle when he does fire.
But when running on the way here was absolutely fine, smooth and happy, kicked down eagerly to get past bicyclists, etc.
Puzzled.com. you'd think if it was a sensor it would take him out or misfire when running, not just starting.

Tried the nanocom, no faults found. But while some sections report figures for sensor readings, etc. but the main section is blank for all readings. Corrosion or wiring issue between brain and fusebox or brain and sensors maybe, but sensor readings still being picked up and transferred via becm on other sections?
 
Took the boys (dogs) to the beach and went rock crawling along a rocky piece of coast to collect driftwood for the logburner, good fun and productive. I really must make a trailer for 4x4 use as the road trailer I have is suffering badly from salt water and being dragged through mud/over rocks. I really need to decide a plan for rust proofing the rear of the truck. At present the new rear floor, inner arches etc (about 10yrs old) are starting to suffer where the waxoyl gets constantly scraped off. Thinking of rust sealing and raptor coating for a more durable finish?
 
Home after the breakdown man's wrench belted the tetchy fuel pump back into temporary life. So we now have a job for the shop to do as well as the MOT in the next few weeks. Rather them with a post lift in the dry in December than me on the drive without...

I can't be any more miss daisy and cruise control gives the same, tyres are ok and have even wear, temp sensor shows correct visa obd, brakes needed attention the other day, now sorted.
ECU? Or fuel map? It otherwise seems to run fine with no smoke. What could i check?
Recently checked and cleaned the MAP sensor but made no discernable change

Performance chipped in the past? Not sure how you'd check that though.

I don't know on your engine but on the P38 there are 2 temperature sensors, one for the gauge the other for the engine ECU. Could you be looking at the wrong one?
To purge the DPF, extra fuel is injected, it could be that after gutting the DPF there have been associated firmware mods that have left it running rich.

I'm only aware of one sensor, but I'm no expert.. I'm sure it only has 2 pins.
It could be running rich, yes but wouldn't that make it smoke?
On the way to work this morning, a new thing.. 5 min from leaving home, cruise set to 30 and revs bouncing between 1200 and 2000rpm. TC unlocked so speed stayed ok.
Set cruise again later and it was ok

It depends on how rich the mixture is as to whether or not there is visible smoke and how can you see small amounts of smoke when you are driving?

It passed the MOT so smoke must be ok?

Do i need to take it to an engine remap garage and see if they can see anything? I've never done anything like that before

I don't know about the UK but here it seems that exhaust opacity has to be quite bad to cause a fail and you are only 10 to 15% below the consumption that might be expected so not bad enough for a fail.
Have you tried getting a friend to drive it while you follow to check for smoke if it's booted?

I've not. I could do though. Or rather get a friend to follow, see what they say.
Three mpg-ometer on the dash is about 20% over if that's relevant

Worth doing a follow to look for smoke because unless it's a lot you will not see it from the drivers seat.
I think the over optimistic dash fuel computer is down to marketing, either that or it's because the ECU firmware has been tweaked because of the DPF delete.
