4.2 TDI - gearbox oil change... where to source parts/oil?

[centurion]

hi,

today I checked with West London Audi and they quoted me ~£210 for the filter/sump, couple gaskets and 7 x litres of oil. Would you consider that being a fair deal or should i approach one of ZF suppliers for a quote too ?

if so i'd appreciate if you could recommend any decent [e.g. reputable] supplier to source required parts for ZF 6HP-26 [Lifeguard 6/Gold oil]?

Cheers
