See that is partly why I ask , there's a lot more to a service than just changing the oil! And IMHO , with modern fuel systems , and the shocking amount of bad diesel , changing the fuel filter is the most important . Fiat , the cheeky feckers , have only gone and changed from an inexpensive replaceable element , to a newer filter that costs something around 100 euro!!
For me , on a service , the brakes are also very important , you wouldn't believe the amount of calipers I see half/fully seized , and pads that have loads of meat on them but the friction material starting to break up and/or seperate from the back plate .
Greasing up the links and hinges too , checking the pipes and wires all around , and the fuseholders , there's loads of little jobs that only take a few minutes that need doing and checking , I find.
