TD5 splutters and cuts out on motorway.
Hi all

I have a td5 110 DC with 180k miles. remapped with bigger intercooler.


In the past week on my daily commute it has started spluttering once or twice after 5-6miles then eventually cutting out once on a motorway hill with EML light on, pull over and restart all is fine for the rest of the 60mile commute.

come home time coming down the slip from Swindon west onto the M4, it splutters once or twice after entering onto m4 and accelerating up to M way speeds and and a sweet exhausty smell comes in for each splutter, but most of the time doesn't cut out but once or twice it has. Once restarted or carries on it doesn't happen again.

Always in the same places the last few days, seems to be fine everywhere else.

Drove it very hard on A roads on sunday up to hereford and it was absolutely fine?

Diagnostics plug doesn't currently work so can't plug it in! never had it scanned as its never worked in my ownership of the 110!
ECU plug is clean used to have oil but cleaned it out.
Injector seals have been done
Same for injector loom.
Fuel cap missing at the moment new one on order.
freshly serviced with oil and filters. 2008 Santorini Black 110 XS USW (Sold)

You'll probably have to bite the bullet and go for a new pump. I had the same sort of thing, as I'm north of you in Hereford we don't get big wide modern roads that have a M at the start( we do have the M50 but where does that go?). I was getting the symptoms when going up a long hill, just when the engine was demanding more fuel(in the old days the governors would be opening up to get more fuel through the injector pump but it's all controlled by the computer). Power would just tail off and you were just left there with a stalled engine. Eventually after a purge cycle or two it would restart but if you could get to spin it round and face back downhill it would bumpstart using the slope.
When I took my pump out it was if I had pulled it out of the engine sump, looked just like thick black used engine oil and as such was slow to go through the fine gauze on the suction port.
Changing the fuel pump isn't as daunting as it sounds when you cut an access hole through the floor. Here's how I did mine....... http://www.defender2.net/forum/topic28189.html

Sounds like the pump, all good garages will be able to pressure test it.

Could also be oil in the ECU plug under driver seat but does sound like fuel pump Thumbs Up

I still reckon mine was caused through some dodgy forecourt diesel, there was too much of a coincidence on a fill up from a different garage to the one I'd been using for the previous 6 months

Hmm could be as its done high miles and as far as I can see, its never been done.

May as well do it! same for the fuel filter on the side as its hanging off, as its mounting bracket has broken. 2008 Santorini Black 110 XS USW (Sold)

Sounds like you may have had bacteria building up in the tank. Cause a thick black substance. Few other reports on here about it.
