Drop links started knocking at 10,000 miles - replaced under warranty without problem.
Booster (auxiliary) heater misfiring with plumes of grey smoke at 20,000 miles - replaced under warranty with upgraded glow plug kit. Dealer excellent and proactive in resolution.
Minor erratic electrical faults - e.g. one-touch automatic electric window switch works sometimes and at others you have to hold it down/up.
Performance is great both in pace and economy. The 115bhp TDi engine is VW's most modern unit for 2003 cars. It has a superb torque range and you can get into the right rev range because it is mated to the six speed gearbox. Cruises quietly at 1900rpm / 70mph so long journeys are effortless.
Handling is the best I've experienced for a full size MPV. Far better than Toyota Picnic or Zafira. Not a Subaru Impreza on the back roads, but is a competent performer and won't leave you exhausted at the end of your country lane / Scottish lochs tour.
Comfort is very good. Seats are superb, loads of room, great view, climate control, superb radio, cassette & six CD unit.
Space is great. Front seats swivel 180 degrees. All others move, fold forward and can be removed. Various seat layouts possible. This car does anything a family can possibly ask of it. Adults can comfortably seat in rearmost seats.
Final compelling point? 5 passenger, German autobahn, 110mph, aircon on with 38c outside, luggage and...45mpg!!!
