My 8 year old Superb Mk2 (had it from new) has started showing a flashing spanner over the DSG 7 speed gearbox in the MFD but the handbook is extremly vague on this and I could find no information elsewhere. The annual service is due in about 50 days but a specific service reminder always appears beforehand so I don't think the flashing spanner relates to this. I therefore thought it might mean a gearbox oil change is required as this is not part of the annual service, although it was changed 5 years ago when Skoda advised to replace the synthetic gearbox oil with mineral oil. Can anyone confirm what this means? Thanks Neil
