Hi Mav I totally Agree with CB1A - Renault are a Joke when it comes to servicing intervals for the 172 !- My local dealer sold me the car yet when i ring them to check the service intervals they didnt know ! I found out the necessary info on here to start with.
I went to my trusted local (VAT registered) garage and they did first service for under £90 while using all Renault Parts (bought from local renault dealership) and this included the Pollen Filter which my dealer wanted to charge £30 + vat for ! (just to buy !)
As long as you use renault approved parts your warranty IS STILL VALID . Renault wont admit this because they will loose so many customers as they take the P+ss with their charges but i checked with my solicitor and Top Gear Magazine just to be sure and you can use any garage which is vat registered just as long as you use ORIGINAL Renault Parts.
Also how come Renault Dealers sell products which they know nothing about ? worrying when you buy the damn car from them ?
There is some confusion on here about the above statments but if you check with your solicitor / watchdog etc...they will confirm this is the case.
Also the service interval is 12,000 or 12 months with either one month or 1,000 limit to keep under warranty.
Hope this Helps
