Disco Tdi fuel sedimenter plug

Time for a new fuel filter so to start the process I tried to drain the sedimenter at the back of the car.

Whoops. The plastic drain plug sheared straight off in my hand. (Honest guv, it didn't take much force!)

The good side is that the threaded part is holding back the fuel. Oh, and the replacement plug was just 58p from a main dealer!

But I'm a little concerned by the weird beige powder that seems to be everywhere in the thread. And curious as to why the fuel isn't coming out at all. I would expect it to get out through the slot in the thread which my replacement plug has, but I imagine the powder is stopping it, combined with the way the shear must have blocked the slot.

Does this powder sound like fuel/water emulsion, once it's dried out? Or is it just the plastic of the plug itself, perhaps over-heated?

And more to the point, has anybody else had this happen? What worked for getting rid of the old plug? I'm considering either drilling it or trying to cut a slot into it for a screwdriver...

Thanks for any tips, K

Used to happen all the time when working on them. You can remove the whole sedimenter bowl for ease, undo the bolt aobe the bowl, think it's a 10mm, then the bowl comes off, in 2 parts, just make sure the seal at the top is seated properly when putting it back!

But then you have to prime the whole system again with the little hand pump. What a drag, takes about 1/2 an hour to do. Frank

I can safely say after servicing 000's of TDi disco's I've never once had to hand prime the system, it's self bleeding, just let it idle for a couple of minutes.

When I replaced the diesel fuel filter and some piping in the engine compartment with a type that uses a transparent bowl I had to hand prime it as the engine kept on stalling.
