I pulled away from the local main dealer due to their lack of interest, when after six months from new the
Ateca threw a warning light and they said they couldn't look at it for a month - I was absolutely staggered by that response. I ended up calling SEAT Assistance who were fantastic - they came out next day, diagnosed the
problem and the day after came back with the required sensor - fault fixed.
Local indie MD Autobahn has looked after our
Ateca since the third service, so for the last three. They provide a fully detailed invoice showing the tasks performed (per the SEAT maintenance programme of course) along with part numbers, fluid specs etc. I'd get the same thing with the Leon, should I decide to swerve away from the main dealer again.
There'd be absolutely no reason for a warranty investigation/claim to be denied by my local SEAT/CUPRA main dealer - I'd hope!
And let's face it, servicing a modern car for the first few years from new is not much more than oil/brake fluid changes and possibly some fluids and spark plugs, dependant on elapsed time/mileage. My Leon isn't a daily and if I keep it for five years it will have no more than 18k miles on it.
