Ok so who's got what? I'm only interested in after market products, rather than manufacturer's 3 yr ones.

There seems to be a massive difference in quotes I've been getting.

Who can recommend one in particular, for covering virtually everything, other than Audi...?

Although I currentkly have an S4, I might sometime in the future have a 3.0tdi or even an RS6, so it needs to cover turbos as well as 4x4.
