For those with the V6 engine who may suffer from the swirl flap motor "implausible value" fault when the linkag wears, there are several threads (including a sticky) about inlet manifold replacement. However, there are some fixes available that don't involve replacement. I was aware of one offered by Fontain of Iver, Bucks for about £250 for both sides (as opposed to the £1200 for replacement). I've now found another source of the same repair - I dropped my car off last night for service & MOT, and was chatting to the owner, and mentioned that the manifolds should be ok, and we chatted about the repairs and he said they did one - I mentioned Fontain and he said he used to work there.. Apparently the repair involves some plastic metal, and they've had good long term results from it.

So, for those withing sensible distance the two places I would suggest for repair instead of replacement are:

Used Audi Specialists in Iver, Buckinghamshire - Fontain Motors » Iver » Buckinghamshire Fontain, High Street, Iver, Bucks and

VAG TUNE SERVICES Aylesbury - Specialists in Audi, Volkswagen, Seat and Skoda marques VAGTUNE, 55 Edison Road, Rabans Lane, Aylesbury. (Which is where I went last night)

On the subject of VAGTUNE, they've obviously not done the work yet, but first impressions were good. A fairly new inductrial unit, small, but a nice clean an tidy office, and a view through a window into a clean brightly lit white painted workshop.
