Hi, sorry, not really sure specifically for that engine type. I'm just getting my Cupra ready for Winter. So far I've:
Checked tyre pressures and inflated (because pressure goes down in colder weather).
Topped up coolant with VW 12Evo.
Checked fluid levels - brake, washer, etc.
New spark plugs in (but the old ones did have 40k on them).
New battery arriving today - the old one hasn't failed yet. But it's 5.5 years old and batteries have to work harder in the colder months.
Lubed bonnet / boot / door latches with White lithium grease.
