Current Niggles then!!
Connector / Loom problem on brake pad wear detector, was repaired but failed again, just can't see outside temp!
Door open sensor (about £80 and stripping out door!) - Does mean have to manually open fuel cap & no 'lights on' sounder
Some of my 'heat tray' underneath has broken away (whilst on the Mway!!)
Drivers Door 'restricter opening arm' is jarring
General switch transfers wearing off
No extreme drama's but just annoying!

I've had most of that done recently. Probably around the 1 day / £300-400 mark to sort that lot out I would guess. Cheaper if you do some of the work yourself, but I would suggest talking to Tony @ A2Cars, alternatively Spike, Sarge or Vince.
Brake pad loom - there is an Audi repair kit which is basically a new loom you splice in, usually in the engine compartment. Not sure which is the loom which covers the external temperature sensor.
Door microswitch - This affects a number of things. But beware that there are several different things which can also cause the fuel cap to fail to open (I've experienced a few - a) switch disintegrated, b) bad earth on that circuit, and finally c) the mechanical connector to the solenoid also failed a few months later). So make sure that you are fixing the right thing.
Undertray - you can get the attachments relatively cheaply, the undertray itself is bulky but you can probably get one off a breakers etc. Tony would be likely to have a 2nd hand one for under the Audi cost. He's also developed a clever little trick to fix connectors where the steel bolt has broken off due to galvanic corrosion.
Drivers door check strap - relatively cheap if you do it at the same time as the door microswitch.
Soft touch switches - I bought a few replacement switches from Audi, and also some pre-soft-touch controls from ebay, so it all looks a lot nicer now.
