I know this will not affect all of you but I know for a fact that some owners have applied to extend their warranty in the same manner as myself.
I think it has been common knowledge for a while that by supplying certain documents to Renault it has been possible to extend the warranty of the car to 3 years. I personally have a letter confirming "all vehicles purchased within the eu after oct17th 2000 are eligible for 3 year extended warranty". The letter gos on to state that all i need to do in this 3 year period is to take said documents to my local dealership at the time of having any warranty work carried out.
I have just called Renault customer services to ask for this to be confirmed in writing to me i.e the same letter with MY name on it. They are now saying no such letter exists and that i have no warranty left on the vehicle. I mentioned people on this site have had their confirmation letters through and was told basically "good luck" when you try to get any work carried out. When I asked to speak to the author of the letter they have cut me off.
I am only warning people as it is my understanding quite a few people have been told they can extend their warrantys to 3 years.
