My dealer barely manages to service my car properly without input from me. Chances of them noticing anything I would have thought are slim.
There is the answer, fit a tuning box and drive to the corner of south east Kent for servicing and warranty work


... I’m being slightly sarcastic, they do a decent enough job, once I remind them it’s a Cupra and not a 1.2 SE.
If the box is removed before it goes into a workshop then they can suspect but they can’t prove it right? (I don’t think)
