My water pump was just replaced as part of a major service just before i made my purchase, not sure if it is N1 (pretty sure it isn't) but the switch to the 1.3 cap is what blew my heater hose. After two trips to sinergy they've now replaced everything they possibly could, bar the radiator hoses which are up to the job at present, albeit a no brainer to replace myself if need be. Graham spent a great deal of time to source the exact material the car needed to ensure it was back on the road as soon as possible, given that sourcing a few cruddy hoses from Japan would take weeks due the the tsunami. Power FC shows my water temp stabilised at no more than 70 degrees everywhere I drive. Top work from the boys at Sinergy I say! Now I just have to wait and see what self destructs next
