TDI Water pump - 2 in 45k

As per the title - our Superb Greenline 1.9 TDI has just had its second replacement water pump fitted and cam belt (as it had been leaked on both times).

Just a warning to others to check - with the under tray, we only caught our first failure when changing the tyres on ramps. The second pump was found to be leaking at the last service. You can miss the leak and we weren't losing coolant obviously until the very end on the first pump and no nticable loss with the second.

We've done above average mileage, but mostly motorway, so keep your eyes peeled. Anyone else suffered similar?
