Hi
@thesmileyone - do you have VCDS? If not I’d say that this should be your first purchase. It’s a big initial outlay but once you have it you’ll use it for everything and more. I bought mine from Grendan, a UK supplier. This is for the 10Vin bundle but there is cheaper options:

For your door warning & puddle lights and footwell lights, order them from
@RobinA3. He can also include an LED upgrade for these items - I made the mistake of getting the footwell kit from eBay (to save a little money) and they wouldn’t connect to my MY central electronics module.
Front Roof/Map lights with the red LEDS that shine down is approx £70 on eBay or £104 new from Audi. You’ll need to change over the internal sensor from your current one. Part number 8E0947135D6PS. This part is shared with the A4/S4 but make sure you get the single vent at the rear of the light.
Rear foor ceiling/map lights - this is the individual map lights, not the single reflector light in newer A3. It’s about £25 from eBay or £44 new from Audi. Part number 8E0947111A. Also an A4/S4 part.
The ashtray delete - this would reuse your cigarette lighter led which will be used to light up the new cubby/pocket.
- cigarette lighter (with flappy lid) 8P0 863 387 A6 PS
- pocket/tray 8P0 863 301 A4 PK
- diffuser/light cover 8P0 864 138 A4 PK
- led light bar 8P0 857 355
User power from ashtray light, feed through. It's just long enough! All parts come to approx £80
Finally, the Q3 climate control - also in pic above.
It’s roughly £85 on eBay but
@ch1z64 picked his up for £12. The part number is 8U0820043G and a small amount of coding needs to be done.
All the above can de down by yourself at the side of the road - just follow the guides on here which document everything you need.
