Does anyone know if VW make a rubber dust cover for the diff lock
between where the shaft enters the housing and the servo unit  - and if
so what the part number is?  It looks like one is shown in the Bently
manual but I could not see it on the parts microfiche.  I have just gone
to a lot of trouble freeing mine off and I would like to keep them well
protected!
