I have a four year old SQ5 with a panoramic sunroof. It creaks like crazy, and despite it being under warranty from Audi they have told me that it’s not covered by warranty. I paid them £220 for a “sunroof service” which involved cleaning and special lubrication. Noise back back after two days! I’ve tried using foam tape etc. still creaks! Any suggestions as to likely areas to aim for? Thanks
