My impeller bummed out a while back, as it runs off the cam and they have to take the belt off to get to it anyway (I think they un-mount the engine for this as it is all shoe horned in place). So at the time I got the rollers, tension, belt & pump replaced. If you are having the belt etc replaced you would be mad not to get the impeller replaced at the same time. Or even the whole pump. I think the pump is £30. This is a common fault on all Seat, VW, Audi & Soda’s. A £3 piece of plastic can cost you over £350 in labour!
Also at 60K I changed my sparks for some pricy platinum plugs. The old ones were corroding from the middle (this was at 62,000 miles)
