I too have a approved used skoda nightmare.i bought a 2016 octavia vrs diesel with 22k on the clock from Rainworth skoda Mansfield.since then I've had no problems with the car apart from the gear selector sensor warning every now and then which apparently is a common fault.since the purchase I have put 8ooo miles on the car and the 30k service warning is now showing,so I popped it down to my local skoda garage to fit it in.I thought it'd be a good idea to do the full inspection service as it still has the APPROVED SKODA WARRANTY (not worth a carrot)and if they found any problems this could be sorted with the warranty.The lovely man at Bolton skoda checked on the computer for the cars service history and to my amazement informed me although the car is now 6 years old that the cam belt hadn't been changed (5years)nor the dsg (4years) hadn't been done,bear in mind I bought the car from a skoda main agent you would've thought all this would've been done to skodas recommendations but NO.so for the price of my service will now cost £1400.since then I tried to speak to Rainworth and they quite rudely told me that this work was all recommendations and if I don't like it speak to skoda uk after 2 weeks the out come was from skoda uk that basically if I'd have mentioned it at purchase they would have come up with a deal(talk about a kick up the arse)so now it's going to cost me 1400 quid.The moral of the story be very careful when buying from a skoda main agent in fact you'd probably better buying a car from Arthur Daley
