If you want to enjoy the benefits of the 3yr warranty on your new Renault vehicle here is what you need to do. (Applies to cars bought in the EU - excludes Cyprus imports!)
Have the vehicle serviced on time/mileage at a Renault dealer.
If you do not have your vehicle serviced at a Renault Dealer then the 2nd/3rd year warranty (which is a contribution system) will be null and void.
Taking it to a local garage, even if they use genuine parts, for a service will still invalidate your 2nd / 3rd year warranty. (after the 1st year)
This is a free country and you can take your car anywhere you like to have it serviced or repaired, but you will loose your warranty.
I havnt posted this reply to make you go to Renault but just as a warning of the consequencies of not using a dealer.
The choice, as always, is yours.
