Hi there,
This might help answer a few things. Have a look at your service book in the manual pack you have. There it explains all the checks and replacements that happen at different intervals and what a regular service should look like.
I've got a 2007 car and on my second service they did what they call a mobility guarantee service, which includes a full safety inspection of the car for wear and tear. They replaced the oil filter (€14.40 + VAT), the sump plug (€1.41 + VAT), they put 4.6 litres of Longlife III Castrol oil in (€20 / litre = €73.60 + VAT) and properly disposed of the old stuff and added more washer fluid (€1.42). They also did a diagnosis DTC check.
All in my bill for the service came to €215.49 + VAT which was €256.43.
This service keeps up the 'mobility guarantee' which is basically the free European wide AA/RAC coverage (which in itself must save about €100 / year) we get whilst getting the car serviced by a main dealer.
They would have changed the brake fluid as well on this service - but since I'd just fitted a new big brake kit with new fluid, they obviously didn't bother - it will need changed again in a further 2 years.
