Can anyone please indicate to me how easy or difficult it is to replace the engine cooling thermostat on the A8's ASB 3.0 TDi engine?
I've seen reference elsewhere to those of you with an A8 who have "just gone outside tonight to replace my thermostat", but my 'trusted service agents' have just quoted me four hours of labour to replace a £30 thermostat.
Is this reasonable of have they misunderstood what's involved? [They don't see many A8s].
Thanks - Julian
