Just reading through this. Mine had been last done in Nov 2016 in the Netherlands (along with a pile of other things when a Dutch person imported it from Germany). Checked it into EMC Autos in Ennis 4+ weeks ago and got it done early this week along with a service for 660 inclusive.
Very happy with the job, it was a 2 day job but worth the wait. I had tried two local garages in the Ennistymon area but neither were willing to take it on for various reasons (difficulty in getting to it, vehicle height, lift limitations).
Was told the belt was quite worn and needed doing. From what I understood, the water pump is driven by an ancillary belt. They had a close look at it and reckoned it looked quite good and didn't need replacing.
A noise started coming from the engine on startup once the weather got colder, the new van belts seemed to sort this.
