I had exactly the same problem. Up where we are, I think the salt gets in and corrodes between the pump’s three ‘cylinder heads’. I rebuilt my pump with a £20 or £30 kit, but it leaked again. I had to resurface/clean the heads and it worked the second time. It’s not a loose bolt problem.
You don’t need to buy a whole new pump, either get the old one refurbished or get a kit from Darwen Diesels and do it yourself.

My pump is leaking from the same plate. There are 3 identical plates on the HP pump.
I started to strip mine out yesterday, but the weather stopped me, after I spent an hour looking for my 17mm Allen socket.

Remove it strip it down in a clean area, on a tray maybe and replace all the seals, link below. I have a couple in the shed I am going to do over the winter months.

I ordered this kit as it contains both types of top seals and the end plate seals.

There's a video on the site I linked which shows exactly what is done and how. The seals in the Bosch pump are easy to change.

The pump seals last 120K miles or about 10 years. I personally can't see the point in keeping a spare, that will only degrade in storage.

I just bookmarked this thread as I'm pretty sure I'll be doing the refurb sometime.
Thanks guys for all the links and info.
I'm doing mine at the weekend, and the tailgate window cables. I rebuilt the starter last night, so I won't be stripping that out again soon.
These BMW TD4s are a pain by comparison to my previous V6, which is still running faultlessly 4 years after selling it to the mother in law.
