TD4, Rough running + clicking from rear offside

Hi All, having a problem with my 53 reg TD4. Its running rough on tickover although not bad enough to stall. It seems to happen only in cold weather, and dispite getting up to operating temp the problem continues. tried fuel cleaners and additives to no avail. Noticed a continuos clicking at tickover coming from rear offside wheel arch area (poss fuel pump?).
Any help appreciated. Cheers Jeff

Was bought brand new to cure a non starting freelander, but it turns out the pump wasnt at fault. I was going to take it back to the dealer for a refund, but as it had been fitted, they wont return it

Part number is WFX000181. Cost me £176.18 + VAT, bringing the total to £207.01

I would ideally like about half of that back, so £100 ovno. Will post, at cost of approx £6. PM me if you are interested.

Cheers
Mike
