Will home servicing affect warranty?

We checked with Mark from www.micksgarage.ie and he told us, "One of the guys here has worked as a service advisor and warranty manager in the past and can confirm that if you buy genuine service parts and service the car yourself, the warranty is unaffected. Also, for those looking to undertake the jobs themselves, the Haynes website has some useful videos on oil changes, filter changes and spark plugs etc."
