Hi all, I'm having the dreaded DPF issues and recently had the car hooked up to a diagnostic who said the fuel cap sensor is buggered, I went and purchased a new one from Peugeot at a ridiculous £100!! and fitted it. Now since the diagnostic ive got my hands on PP2000 which has showed me a few faults like dpf fluid low etc (ive had this filled and still now joy) anyway..the cap fault is still showing and try as i may i cant clear the fault?? im only 1 day into PP so im probably missing something but to be honest i cant clear any of the faults at all??. Any help would be great i'm starting to think the program i have may be the problem...

Thanks in advance.

Sorry its an 03 plate 2.2HDI 807

Its a right old, faff, trial & effort. I finally sorted mine. Which was a mixture of things - I replaced the dpf, diff pressure sensor, and fuel cap sensor - Does it say cap is present? Have you cleared the codes??
I would list the codes mate. Did you buy a new cap?? Its unlikely the cap - (check to see if magnets are present) - Its likely to be the fuel cap Sensor - I bought one last week for £38

Says cap not present even though ive fitted a new sensor, i'll hook it back up and get the codes but one of the probs is i cant clear any codes with PP and yes magnets are present...i think if i could clear the code it would probably realise its ok now.

Hi again, I've managed to get rid of the additive level low warning (not quite sure what i did but it worked!) and scaned ECU and faults are as follows:

Filler cap presence switch 4320...I put a genuine new one on just 2 weeks ago

Fuel gauge 4315

Additive low level sensor 1283

Fuel additive ECU 1282

Fuel additive injector 1284

Fuel additive pump 1283

The injection ECU 1320.

This was done with PP, Surely all these parts have'nt failed?? could it be that the additive ECU code above is causing all the other faults?? Its driving me mad now im already a few hundered out of pocket with additive/sensors diagnostics etc and its no different lol!! I'm seriously considering getting the bugger deleted. Ive read in a few places that additive ECU can fail and also read after fitting a new one that too needs programing?:confused:

Hi, Did you ever get this sorted ? I have the exact same list of fault codes as you have listed above. Im going around in circles at the moment :confused:

Did you clear the faults after you fitted the cap presence sensor? They will stay on otherwise. Spurious faults are common among the genuine, clear them all and see which come back. The returnees can then be sorted.

Hi, in the end I gave up trying to decide which part/s needed replacing and spent £500 having it deleted which solved it. I had 9 days of trouble free motoring before the brake servo failed and 4 days after the the turbo failed also, 3 months of owning left me in financial ruin lol! I decided enough was enough and sold it. I'm now nestled safely in the bussom of a BMW.
I can only advise deleting the dpf, the cost is scary but repairing what could be numerous parts could easily exceed that..my fuel cap sensor alone was £116 from my local dealer. Hope yours treats you better than mine did, best of luck.
