SuperBmE

Hi, been told by garage i need a new sleeve and clamp set, I'll fit this myself, but before I get old one off does anyone know the correct diameter I need, Seems conflicting online. Thanks

As per title really, switch in drivers door will lock all.doors but not unlock them, which is a PITA when picking someone up as you need to reach over and open door. Did a little experiment where I removed passenger switch and connected that, that seemed to lock and unlock, I've just bought a switch from ebay and think I've been unlucky as aftwr fitting that it's just locking aswell, no unlocking!! So is this a common issue?

Bonnet seems to close sometimes 1st go sometimes 8th, I've taken apart the top hook etc. Regressed it, Seems to be if you open Bonnet you need to then push handle in far in passenger side. Think it may be cable...is it correct that these have a 2 part cable 1 to a box in passenger inner wing then another to Bonnet release?

I'm not sure if I've explained it properly, I've owned 15+ cars and I've never had this in any other car on the mway, I assumed when Ac/CC is off then a flap or some such would close, but the Superb seems to be freezing on the mway.

Nobody?

I've a 2011 2.0tdi elegance on 110k and as above really, When I have my CC off and I'm driving I notice cold air coming in through all vents, especially bad at motorway speeds, CC works fine in all other aspects, any ideas what's wrong with her?
