As what Ekona has said, except best to purchase all the parts required and take them along.
Most garages will gladly carry out your sevice with you supplying all the correct parts.
The two benefits of this route is that you will know that the correct parts have been fitted to your car, and secondly, it will be cheaper. Win Win
I carry in stock all the correct parts for your servicing needs and they are good to go same next/day.
Drop me a PM if I can help you further.
