I'm not sure what the PR code for our Freetrack's suspension is to cross-reference to an ETKA parts catalogue.
Loads of options for the altea/altea XL chassis. Best bet might be ring your local dealership and get them to check their parts system vs. your VIN.
Other option is eBay, the attached screenshot is an advert for a pair that might help. I've ordered a few bits from them for my Freetrack TSI (cat and centre exhaust section and a drive shaft, came quick and in good used condition).
Changed the front pads on mine today so took pictures of the paint code marks for you of the standard front and rear Freetrack springs.
Use the OEMPC website above (or ETKA if you have access to it) to find the corresponding part number. Alternatively give your local dealership the paint code and they should be able to work it out for you.
