Okay, the car was dropped off today. They had a passat cc in reserve though this would mean although I could park it in the garage, I wouldn't be able to get it out. I got a VW Fox instead, which was remarkably roomy though still less punchy than my old fiesta 1.25-zetec.
Anyway, they tell me the master cylinder has been replaced (along with an engine cover mount). Will be picking it up tomorrow morning. Anything special that I need to do before I drive off home? Will definitely drive it around for a bit first but is there anything else I should check?
