Have a works van, Peugeot Partner 2.0 HDI with a Siemens system, a year ago the van would not start, code reader pointed to ECU needed replacing. Had a re-mapped unit fitted all fine for nearly a year. Then van started going into limp home mode, turn off, wait 10mins then ok again but intermittentaly would go into limp home mode again. Code reader stated major ECU error, sent back to supplier who checked and returned saying all ok. Brass filling found in fuel filter, leading to high pressure pump faulty, van has done 190k, pump replaced, but still goes into limp home mode. Wiring loom checked as limp home mode comes on ramdomly. Lads refuse to drive van, used myself for last 2 days, covering 25 miles each trip to work and home. If keep under 2500 revs seems to last longer before going into limp home mode but does also look to be a time thing, ie goes at the same points when travelling. If you go over 3000 revs happens more often. Had the ECU checked by somebody else who has given the all clear. Now thinking about injectors, but drives fine, does not miss or hard to start. If you let it stand and rev it hard will not go into limp home mode. Van does not smoke any colours ideas please?

Hello and Welcome to justanswer....What is the code you have now - currently / latest ?Has any work at all been done on the fuel system - since.. and exactly what parts have been replaced thus far ?What sort of garage / type of equipment is being used for the diagnostics?Rgds, MIKE.........................................
Thanks Mike,The guy who looked at the van is a one man band, ex-peugoet using peugoet software to read codes. Each time the codes are different and random. He has a mate at Bosch as well, and has tried somebody there for info. He believes it's to do with the loom connections to the ECU being corroded, which he has cleaned believing as you drive along bumpy road sets it off giving the random codes. But having driven the van a lot further not so sure, basically after another opinion. Once in limp mode, you un-plug the 1st connector on the ECU which resets it and you are off again.On the actual fuel system only the high pressure pump has been replaced and the fuel filter cleaned.When standing the van runs fine, when driving does not miss.Whilst checking over he has found and replaced a couple of chaffed wires on the loom but no difference. Looking at possibly getting some loom ends from a scrap car and replacing to eliminate.
Hello again - thank you for your reply -and info...Absolutely - certainly, corrosion / problems of any kind on the ecu multiplug will cause this - and random codes...usually resulting in a complete breakdown..I have known the ecu -and the loom have to be replaced to cure this - it depends how bad it is Given the known issues that you have with the loom / connectors - that can and very probably is causing fuel issues so you need to concentrate on sorting that side of things first... thats certainly going to be your cause of your issues here now. So thats the way forward on this now.
Im very pleased to have helped you - Let me know if I can help anymore...
