hi in 2020 i bought the first edition seat leon mk 4 with the 1.5 ETSI the mild hybrid after about a year a letter from the DVLA saying that seat uk had informed them with the incorrect fuel type and taxation class and a new V5C would be issued together with a tax refund . the amended V5C had the taxation class as alternative fuel car and type of fuel as hybrid elec well i purchased a cupra leon 1.5 ETSI last year and the V5C has the same mistake on the V5C it reads taxation class petrol car and type of fuel petrol im still trying to sort this out with seat /dealer . if anyone who has purchased a 1.5 mild hybid ETSI on this forum could look at your V5C document and see what has been put on yours it would be much appreciated
