That was my thoughts Richard. His diagnostics werent up to the job. Espically as he couldnt even find peugeot on it and used citroen, and it was just a generic hand held thing. It really needs the proper peugeot equivalent of lexia.

Depending where you look can get umpteen different causes. So no further ahead. But the mechanic says, when the car says a fault in the engine emissions system, to start by cleaning the dpf. Use mr muscle oven cleaner, get under the car, remove the sensor on top of the dpf and squirt in the cleaner. Leave a while then start and run engine for 20 mins. Must be worth a try for a quid out of tesco, or even from under the kitchen sink. Then top up Eolys, and possible clean egr. Then check the relays for the glow plugs, then change glow plugs. All that seems a bit hit and miss to me.


He pours what in DPFs?

Doesn't this mechanic own a pressure gauge? If it does show excessive pressure, then you'll want to know what's clogging it - soot or ash. If the former, you need to fix why it's not regenerating or you'll be back to square one in no time.

Having said, I can't find a P1331 for PSA vehicles. One for Ford that points to turbo-overboost though.

I have heard before about soaking a dpf in a bucket of water with mr muscle in it then power hosing them clean. My problem just now is Im in a bit of a crash and I have not much interest in the 407 since buying gabby. I think thats testament as to how good gabby is. I have only got 4 wheels the same onto the 407 last week and thats a while since I knackered one and found the spare cracked. I did think the garage man yesterday did not seem qualified enough or have good enough diagnostics to do anything. As far as I am concerned I am no farther ahead, its still as of now guesswork as to how to fix it. The plan is to take the dpf off alltogether for an inspection and clean. I just need the motovation to do it. The car starts eventually and runs very roughly then smoothes out but wont rev over 2200 rpm and cuts out if you try to get over that.

I know what you mean about the simplicity of a TD vs complexities of HDI's. One big difference being just how protective the ECU can be when it detects abnormal conditions, especially when related to legislated emissions standards.

Given your fleet, I'm surprised you don't already have a diagbox. :) Just one use and it's paid for itself.

I think that is going to have to be purchased. Along with a suitable laptop to run it. The 407 definitely needs a proper interrogation by one. Yes, it won’t do any harm taking off the dpf for a clean, but it still needs diagnosed, and if it needs Eolys then it needs resetting in diagnosis I would think.

Yes, I think a Diagbox will be a good investment Davie but of limited use on Gabby and Lilpug!

Only ECUs Gabby has is airbags and engine and Lilpug just engine unless it has ABS...

Hope you get sorted Davie . I'm avoiding modern Dpf diesels from now on , the freelander doesn't have one and it must be one of the last ones before they were standard fit . I'll either run this forever or get a big petrol engine if I ever change .

Just looked at this thread and cant believe its over y weeks since bigpug has moved! The DPF is off the car, putting a hose on to it and the water trickled through it. Now after 3 goes at cleaning it water is no flowing through it freely and a fair fit of black crap came out. We have storms forecast again, but the next dry day I get it shall be replaced onto the car, and see if it goes. Then a play with the lexia which I havent done either yet and hopefully either find out if I have cured the problem, or if it needs further work.

It was chucking it down this morning, it has now dried up but will be dark soon. So dpf not refitted yet. Im waiting until it is refitted and hopefully the car started before I start in the diagnostics. Can anyone tell me if I need the engine running or ignition on for the lexia?

Finally the dpf is on and engine running, its off the ramps and in the drive where the extension cable will reach so I can sit in it and play with the lexia to my hearts content. Its running better, there was a large amount of white smoke for a while once gabby gave her a hand starting. That would have presumably water in the dpf burning off. Still it has the eml on and dashboard still saying anti pollution system fault. When i try to interrogate it I shall write down everything it tells me. Remember my pathetic grasp of computers? Highly possible that I will get very frustrated in a day or two. I shouldnt really have done that today, im not out of crash mode yet, and I now have an hour and a half to have a shower, have a load of funny chemicals, get dressed and go to the shop.

First thing I'd do Davie is clear all the errors, let it warm up and take it for a spin. Then do a global error scan.

This way you'll know what errors are current for sure. If you don't clear them first, you could end up chasing errors that have cleared.
