Good to know - will try that if I don't get this to work quickly/easily - as
I've already spent the $100 on the entire used part...still way mo better
than $400+ plus labor...

Thanks again, Ti

I had a central locking pump go south too, but instead of replacing the
entire pump box -- $$$$ new, and $$ even used, I followed the info from this
AudiWorld tech article and went to a local Pick-n-Pull yard and dissected
pump box from a '97 VW Jetta, and got just the internal pump bit.  I
transplanted it into my pump box -- total cost $8 and it's working like a
champ again.  No recoding of new pump necessary when done this way.


The VW pump box part number is 1H0 962 257J and the internal pump appears to
be more robust than the B5 Audis'.
