Do realise this has been covered before but thought, I would run through it with you guys before putting planet on to check stuff.

The only thing i think that may have caused this, is possibly the change in driving habits and its not getting a chance to regenerate. I changed jobs about 4.5 months ago and went from a good blast at least twice a day at motorway speeds, to driving about a 1-2 mile a day to work. This i suspect maybe the problem. So do you suspect a long drive or one at above 2000 revs would get it regenerated then reset the fault through planet. See if that works ?, any advice would be helpful :)

well took it for a long run along the m8 and back this did not fix it so ran planet. Which showed Glow plugs/ relay require replacing. There was another fault that showed up

"Additive system Fuel tank cap presence sensor"

on closer looking at the Diesel fuel additive control unit it came up with

"permanent fault. Cap presence sensor signal. Open circuit"

There is no noticeable drop off in performance or fuel economy.

any ideas will pay a visit to peugeot ecosse when i can

You need to replace fuel cap sensor and check cap for magnets, car won't regen as is, think sensor is £40ish from dealers.

And as above relay or glowplugs too.

Glow plug fault is nearly always present and does NOT mean anything is actually wrong.

Cap sensor will stop a regen try first as said then test glow plugs in situ for current draw before replacing IF needed.

FWIW I had the glow plug fault, had new glow plugs put in, and this cleared the glow plug fault and a regen fault. Although what had already tipped me off was a couple of bad cold starts.

I would remove the particle filter and cat and have a remap done :thumb: leave the canister and pipework in place for the new legislation on MOT's later this year though :thumb:

Just a follow up to this CAB.

Had the fuel sensor replaced this morning at a Peugeot specialist who said it was quite a common problem and this cured the problem. As the warning is gone from the car on start up. They did say that they suspected that there was a ECU(not main)that may have been damaged in the process which may see it come back in 6-7 months but not to worry to much about it. Will replace that after end of Feb, as will be too busy making final preparations for a trip to Germany next month

Sometimes cars with seperate additive ecu can have ecu issue.
But only in such that when the fuel cap sensor fails it can knock the additive ecu out but unplugging the electics to it with ignition on then plugging it back in brings it to life without any issue later on.

Makes sense. I'd heard that pulling and re-seating the fuse did the trick. I just assumed it was crud on the fuse. The ABS unit can sometimes suffer with the same issue.

That's on 307s of course.
