Try this company which dealt well with my A3 for years and I thoroughly recommend it. Michael Summers is reliable and honest. Nearly as important is that you get to speak directly to him. Whitstable to Biddenden is more than an hour of travel, but desperate times call for desperate measures.

That's a good idea, but let me add a word of caution. Many of those products contain caustic soda which can wreak havoc on many metals, paints, and fabrics, as well as human tissue, so flush it well afterwards with lots of water.

You're right, the turbo should last a lot longer than 5000 miles. Possibly the oil feed is not sufficient, though I would not know what to do about that. A question for you first: has the car or engine modified in any way for better performance?
Now we are getting somewhere. If I understand correctly the right front & rear door locks always work, the left front & rear door locks sometimes work, while the boot lock never works.
The drivers door lock is the important one here as it controls all the others. I suspect there is a fault on that lock and suggest you get it tested either by an auto electrician or by Audi. It is not an uncommon problem.
If I recall correctly each sidelight has a separate fuse, so the problem is more likely to be the switch.
Fuse and fusebox locations will be in the car handbook if such things exist still.
I am not sure what is not working so please clarify whether you mean the electronic fob, the metal key, or the central locking mechanism within the car.
The springs (there are several of them,) separate the two lumps of metal that constitute a DMF, thus providing some rotary cushioning between them. The arangement is similar to those in a clutch friction plate if you are familiar with one of those. When one or more springs break, the two lumps of metal (the dual masses in other words) smash against each other, which is why you hear a rattle initially that soon becomes a knock as more metal disintegrates.
Which is precisely why neither pads nor discs should need to be changed. If you have a delayed response when pressing the brake pedal I suggest the fault is elsewhere, such as an air lock, a partially seized caliper, a defective servo etc. Be sure what the cause of the problem is before throwing money at the car.
It's possible a spring has broken in the DMF, though other possibilities should be considered before booking it for repair. It's a common fault in old DMFs, and will inevitably get worse.
It would be worth getting the clutch done at the same time, even though it will add a lot to the cost, much of which is the labour charge involved in removing the gearbox.
Light scoring should not affect braking effect once the pads have bedded in. Are you sure you don't have a soft pedal caused by air? Or perhaps a faulty servo? It would be worth taking it back to the dealer who sold you the car for rectification before the guarantee, such as is, runs out.
If you are concerned about the degree of wear you could measure the disc thickness.
You can not be sure, which is why you need an alternative opinion from somebody you do trust. Do you or an aquaintance know of a Audi specialist who can be trusted, preferably an independant specialist rather than an Audi dealer?
I can recommend such an independant company in Biddenden, Kent if you are prepared to travel that far.

The dealer's incompetance in diagnosing and rectifying the fault is surpassed only by his audacity in offering further work as a courtesy. In my estimation he should be resolving the fault without further charge, but can you now trust him?
I would take the car elsewhere for another opinion on what is wrong with it before further discussion with your dealer.
