c5 diesel filter

Hi, I tried to change my diesel filter today but the new one is different. The original has a connector with two terminals fitted to the top cover next to the pipe and the other pipe end just below the top one at 90 degrees. The new one is missing this connector and the lower fuel connection is a socket not a pipe end . the new one is a MAHLE KL 431 which is the style most places list . Can anyone help me out. Regards John.

Sounds like you been given the wrong one...

There is two types of filter houses... Why are you changing the whole house?? Why not just the filter, the one with the electrical connector is easyer to change then the Bosch one in earlyer Xantias...

Disconnect the two pipe on the top by squeezing the white bit, unplug the electrical connection, and the OUTER unscrews off leaving the middle bit inplace - this then lifts out with the filter attached, the rubber seal sits on the top lip just above the thread...

If it is like mine they are exceedingly tight, I had to use a block of wood on the milled ring and belt it with a club hammer to release it then use mole grips for the first turn. Getting it to seal wasn't any easier.

Is it this one?

If so, the outer ring screws off - bit like a Kilner jar.

Yours may be like the one in my mate's Berlingo then.
I didn't actually see it but they broke the clip at the last service and he had to buy a new cap, around £3.50 IIRC. One dealer told him that it wasn't available separately and he would have to buy the whole unit at around £47.
Second dealer said they sell scads of them as they are easily broken.

Is it a 1.6 HDi? service.citroen shows the sqaure type for this engine - and no separate element is listed

Seems like a retrograde step to me, but not for Citroen I guess, as then they can knock out new filters at £50 rather than a filter element at £5

Note that the filters fitted to cars with and without a FAP are different, although they look pretty similar on the parts database - probably you have been supplied with the wrong one.
