weldted Posted July 1, 2021 Share Posted July 1, 2021 Possibly a different set up, but we had no end of problems with the EML (Engine Management Light) coming on in and out of main dealers both in the UK and France, sometimes it would go for weeks without any fault other times could not drive down the road. Various fault codes would come up. Finally to it to an independent garage. They kept it 2 days test runs but no fault took it out again and again. Finally it happened, on inspection there was a very and I mean very small amount of corrosion where the plug goes on to the common rail. This was cleaned and for the next three years it never did it again. Link to comment Share on other sites More sharing options...
tonyishuk Posted July 4, 2021 Share Posted July 4, 2021 I seem to remember from a thread long ago, that similar faults were occurring where a pin in one of the multi-sockets was not crimped properly. After a while, movements in the wiring and corrosion severed what little pin to copper wire finally showed the fault. I am afraid I have no idea which and where the sockets are likely to be the culprit . Rgds Link to comment Share on other sites More sharing options...
Camlyn Posted July 5, 2021 Share Posted July 5, 2021 Thank you. One more thing to be aware of. No more issues so far, but I'm only driving it locally. I'm looking at OBD logging to see if I can produce evidence for the garage Paul Link to comment Share on other sites More sharing options...
steve_f Posted July 5, 2021 Author Share Posted July 5, 2021 Hi Paul, Apologies for the late update. I did see the message notification email last week on my phone, but I was travelling in Scotland, and needed to login using the computer which has the login/password for the the forum - it would have been a lot of hassle to try to do it on the phone. I'm happy to report that the van covered over 1000 miles in the last week and a bit without any problems at all. I'm cautiously optimistic that the problems are now resolved as a result of swapping the ABS ECU. I'm none the wiser as to why an issue with the ABS ECU would cause the engine to cut out though. The dealer I used was Perry's but the van was on its fifth visit and went through several unecessary "fixes" during the troubleshooting of the issue. I also lost confidence with one branch of Perry's so took it to another where I eventually had success. Regards Steve Link to comment Share on other sites More sharing options...
dickydo Posted July 8, 2021 Share Posted July 8, 2021 Hi Steve f Sorry if this post seems too simplictic or irrelevant but the two highly likely issues are the earth strap I was quoted vast sums of money by 'reputable' Garages to repair/replace the ECU unit for very similar problems to yours before a loca mechanic said the engine battery needs a really long charge because my van had been left for weeks then only driven short distances Once I went on holiday in Italy the van was faultless - no lights on dash or cutting out, having driven over 3k miles since Whatever your situation is now I hope your problem is solved Link to comment Share on other sites More sharing options...
steve_f Posted July 8, 2021 Author Share Posted July 8, 2021 Hi dickydo, I agree, earth strap and battery should be ruled out early on when troubleshooting these kind of issues. I fitted a new earth strap after it was suggested to me earlier in the thread and fitted a new battery in January. Both simple and relatively low cost. I've also fitted a trickle charger from the solar/leisure battery to the starter battery to keep it topped up, which was also low cost and easy to fit.

Camlyn Posted August 31, 2021 Share Posted August 31, 2021 Hi Steve How are you getting on with the fix to your van? Did it actually fix the issue? I've been driving around on short trips for the last couple of months, but a holiday without the van meant that I haven't really run it for any distance, so I took it away for the weekend over the bank holiday. I was on the return leg of a 350 mile trip on the A34, without a hard shoulder, and had the same problem again. Dashboard warning about Hill support being unavailable accompanied by loss of power. I managed to get to a relatively safe spot on the side of the road and based on my last experience, expected the light to go and for me to be able to move it again. 30 minutes later the light was still on, but I was able to manoeuvre the van to get it into a safer spot, but I didn't want to try a run up the hill to a layby as I wasn't sure what power I'd have. I called the AA out and got a Police escort up the hill into the layby. The AA was able to find an error code this time and sat behind me as i drove to the M40, rather than me be recovered. It drives around fine again now, though the light is still on. I've booked it back into the Peugeot garage again, for another diagnostic, and I have the error code in case it mysteriously disappears again. The error I got was 'P0234 - Turbocharger/Supercharger A Overboost Condition'. I had a dig around on the forums and it seems that this condition is accompanied by the vehicle losing power and going into limp mode, which sounds familiar to me!!

mikefitz Posted September 1, 2021 Share Posted September 1, 2021 the error I got was 'P0234 - Turbocharger/Supercharger A Overboost Condition'. Paul The turbo on The Peugeot is a variable vane turbo controlled by an electrically operated actuator bolted onto the turbo, (perhaps not the ideal place for an electrical actuator). if the vanes get 'gummed up' with carbon, the actuator has a hard time trying to move them. Eventually the vanes remain stuck in the wrong position, or the actuator fails, or the mechanical link between the actuator and vanes develops so much wear the control is ineffective. The vanes position controls the boost pressure, so if they are in the incorrect position, the boost pressure can exceed limits. There may be actuator partial failure or a loom/connector issue. The usual fix is a replacement turbo with calibrated actuator. Its also possible the sensors reading boost pressure or the electrical connections are faulty. The issue can be intermittent, perhaps occurring after a period of high power demand. A manufactures diagnostic system should be able to pinpoint the problem area. The turbo replacement is expensive so its useful to discount all other possible causes. Mike Link to comment Share on other sites More sharing options...
Camlyn Posted September 14, 2021 Share Posted September 14, 2021 Thanks mikefitz I took the van into a Robins & Day dealership and they did their standard diagnostics, which also included a range of checks on tyre treads, wiper blades etc, and gave me a report that said they had updated the ECU. I called and pressed for more information about how they carried out their troubleshooting and what they found, but got nothing more than "we found no mechanical issues". When I went in to collect the van I pressed for more, and the sales admin gave me slightly more information from a sheet that wasn't shared with me, regarding air pressure being wrong and a software update to the ECU being applied to fix the issue. It sounded a little more convincing, but I am still sceptical about whether they have actually fixed the issue or not. Time will tell and I've got a 200-mile trip this weekend, so hopefully, I don't end up on the side of the road again. Paul Link to comment Share on other sites More sharing options...
