I do have a selection of magnets but almost no black spray can tops.
I recently had a 'major' issue and replaced the filter. don't know what the story was, but it was resolved by recoding with TunnelRat and Fordscan.
However, this was the contents of the filter:
The black bits are worryingly, metallic and nicely centred by my magnet. The only source is likely to be the HP pump, which was a recon around 80k ago.
But when I first had the major, major issue of glow plug lamp, whatever the error code, Fraud changing an injector for a small fortunate, blah, blah,blah and I changed, cleaned everything myself, and this is the result of the first tank sweep with a magnet:
and this is the contents of the swirl pot before cleaning:
All of it is dust, no small obvious bits. I did not shine a touch on it so don't know if all that glitters is .....! But it sure as hell was metal.
As an aside, I fitted magnets everywhere, including one in the swirl pot. Difficult to reclaim it, but if it is catching any particles, so much the better. Also have some sloshing around in the fuel tank, a couple on the filter itself and some sandwiching the fuel line to the pump, whcih I recently checked and they were clean.
