Rear Lights modified

What are the correct ones ??
Paolo, it depends which dis screen between speedo and tacho you have.
If its a basic unit with no failed bulb warning, you can fit pretty much any led bulbs.
If you have a dis with failure warning, this function will need a lead inserting to negate this function.
Tom Cunningham, Timmus converted mine for me.
If you want leds in the indicators then a modified flasher unit is required.

I have basic tacho without bulb failure warning. But if I install the led bulb for brake/rear lights then I have EPC lighted on tacho. If I remove the led and reinstall the traditional bulbs after few mins EPC goes out.
 
Basically canbus led bulbs ( like the one I have tried ) just have built-in resistor. I might try to buy another couple of canbus led bulbs

Just FYI.
I haven't yet looked into the bulb holders on rear light of Audi A2, but canbus ready LEDs can be big problem in some lights.
The problem is that resistors (which get hot) are on the part of the bulb that goes into the bulb holder and if this is to close to some plastic, it can melt it, because it is not designed for such heat, since incadesence bulbs do not make so much heat on that part.
My friend had melted bulb holders on Megane due to this problem.
 
so it would be better to take normal led and calculate the absortion different in watt and consequently the right resistor ?
And use a high power resistor. At least 2X the actual power (I squared X R) dissapated. They will dissapte the heat more easily.
