Everything is working fine.
Great webshop, very good communication, fast shipping, good packaging. But never understood why the Fusion range are only available to some cars - and not mine (2009 Peugeot 407 sw 2.7 hdi).
Great customer support!
Instructions for DIY installation should be more detailled and specific for every single car model. Simple things as intake air filter position makes wiring more difficult in my fabia than in volks.
