So my MY16 Multivan has been diagnosed with a most likely head gasket issue between cylinders 2 and 3. It's got 200 and something thousand km on it, is this classed as within normal wear and tear limits for these vehicles?

Picking up a Golf R 7.5 in 2-3 weeks. Car is in showroom , locked and with sold on it. I am recently retired, from Adelaide these days, and my other car (for now at least) is a 2014 VF CalaisV which is classed by Shannons as highly modified (Blown etc.) as my daily. Can't wait to get the 7.5 after...
