I am about to do an oil change on my 2009 Passat CC 2.0L TDI 125kW. I was looking at using a suitable vacuum pump, either hand-operated or electric to suck out the old oil via the dipstick (as the dealer mechanics do) rather than go via the traditional sump drain plug route.

Does anyone know where I can buy a reasonable vacuum pump relatively cheaply; or does anyone know if you can hire for a day from Kennards, Coates or anywhere else?

If I end up just going via the sump drain plug route I'm assuming the only place I can buy a new sump drain washer (and plug perhaps) is from a VW dealer. Haven't seen anything elsewhere - does anyone know of any suitable alternative to dealer - assuming though that dealer is going to charge some ridiculous price!

Cheers.
