I went for named items for £41 a month, paid by direct debit monthly so doesn't expire at 100K miles or 5 years. Mine is an 08 plate A4 Avant 2.0 tdi with 145k on the clock. Things go wrong so its best to be covered.
ta for the advice/opinions. i personally think - as w/ virtually everything from Audi - it's WAY overpriced. might turn out to bite my ar$e but i think i'll just put off and take it up if i start getting horrind noises from the engine or soemthing :-D
As an example just look at the posts about oil pump issues on the 2.0 tdi. Mine cost £250 excess to get everything done, I have seen prices around £2k+ for the same work. also the dual mass flywheels are around £1200 to change.
For me personally its worked out ok, and I get breakdown cover with it. Over the last five years it has cost me around £2500 in warranty fees and had around £6k+ worth of work done.
