not sure about the aux belt being done, i rang renault and told them a renault specialist told me it was coming from the cam belt! i said that it had been done at renault march last year and said "isnt there a warrenty on parts fitted here?" he then grummbled a little bit and jus said bring it in on monday the 23rd. i asked him if it is free and he said he isnt sure?? WTF so im going to bring it in and tell them not do any work without ringing me first, if they say its the aux belt then il say it should of been done with the 5 year offical service history! if not then im screwed.
