My 2019 JDM Mk3 is going for its first MOT (or shaken as it is known here) and 3 year service. I've done about 21,000 km. The service schedule in Japanese just says 40,000 km for CVT fluid. No mention of mention 2 years - just 40,000 km. My garage (not a Honda dealer) quoted me £86 to do it. I agreed to get it done as CVTs are very expensive if they go wrong and the summer temperature here is pretty high so fluids do deteriorate. I have no idea why Honda in Japan don't think it is necessary after 2 years (or even 3 in my case) but is necessary in the UK. The garages love changing the brake fluid and engine oil much more often than needed - all grist for the mill. Since they offered to do the brakes for only £20, I agreed as I suppose you can't be too careful with brakes. They claim local conditions can cause water condesate to accumulate in the fluid which can then vaporise under heavy use going down one of the local mountains. An engine air filter costs about the same and I suppose that is worth getting given the cost of fuel. It is sometimes quite dusty here thanks to the Gobi desert and China's polluting industry.
With the MOT it will cost about £470 in total which feels reasonable considering the MOT is for two years and it includes two years of minimum legal insurance. The stories about how expensive shaken is and how a car can fail for having a scratch on the headlight are nonsense.
