Seeking Assistance in Locating a Hydraulic Roof Pump or Motor Seal.

[Dudeta]

Could someone please tell me where I can locate the E46 hydraulic roof pump's rotating shaft seal?
There is fluid within the electric motor, therefore I suspect the leak is coming from the shaft seal; I fixed mine pump last year, but it still has a leak.

I have been searching high and low for a tiny enough seal source in the UK, but none have come up.

Is there a real-life part number for it? I doubt so, but it was only an idea.

I thought you said the dimensions were 3 mm ID x 8 mm x 2 mm. From what I've read, the proper dimensions should be 6mm x 16mm x 4mm, therefore this one seems on the tiny side.

it is indeed a very small seal, probably why I'm having so much trouble finding one.

Hold just a second, I believe you're correct; my callipers seem to be malfunctioning.
The measurements were apparently halved by my callipers.wth

It is tiny, that much is true. 

[Dudeta]

No, that's wrong. They only sell the whole unit.
