Planet help needed for DPF on a 307

[gumby6371]

I'm a bit confused by the other halfs 307 1.6 HDI.
It's been pretty gutless ever since she had it with poor economy and the occasional anti pollution fault.
Took it to a diagnostic place today as my planet skills are limited at best, they said DPF was 76% full and it had an EGR blockage which was probably causing the failed regens.
I whipped the EGR off (when I say whipped I mean dismantled the engine bay, scraped knuckles, pulled a hamstring stretching and contorting my body to reach the bloody thing and swore A LOT!!!!) then cleaned it up with some brake cleaner.
Put it all back together and took it for a blast on the motorway keeping the revs between 2500 and 3000 revs for a good 30 minutes.
Slapped planet on it tonight and got engine fault code P1457, filter not present????? WTF!!!!
It did say the filter was down to 51% load which is good but confusing if it isn't there but fluid and pressure differential were both at zero.

Can I safely 'ass-ume' a dodgy pressure sensor is at fault and it isn't the DPF fairies gutting the offending item for me?

Can anyone with a knowledge of the 1.6 110 engine give me the first clue where the sensor/sensors might be located in the ridiculously cramped engine bay please?

Further info gleaned tonight is injector correction values are good 0.4 max on all 4 and turbo pressure about 20 mBar under reference at idle and less under load which I'm guessing is good/not too bad

Thanks as always

Hi guys,
Sorry lozz that's not correct for the 1.6 the filter is mounted vertically in front of the engine and the sensor is in the offside front corner of the engine bay.
I'll take some piccies of mine later if that will help.

Thanks gents, pictures would be great

Now I look at it without swearing it pretty obvious

That's the one, I've just been out and taken the piccies lol.


And the lines.

If you try to blow the lines through make sure you don't pressurise the sensor or you'll knacker it.

[gumby6371]

Are the lines likely to get carboned up?

I suppose planet would pick up if the sensor was duff?

[OllieNZ]

The top line could fairly easily especially with fuel being thrown down the exhaust. I'd take it off at the sensor and blow if back into the exhaust.
Pp2000 will throw up a couple of different faults for the sensor but if the internal membrane is holed that could cause the fault you have.

Thanks Ollie I'll have a look
