Day time running lights not recognized on audi tt 08?

Re: Day time running lights not recognized on audi tt 08?
V and W is way different you guys, Yes the LED's are rated for the appropriate voltage and yes the other bulb is rated for the same voltage, however W (watts) indicates the resistance or power draw from the system if the audi system recognizes a short and has been programed to read a variable wattage range from 11-13 watts and anything below that spectrum is a fault. So what you need to do for an LED is put in a resistor so it draws more power from the system and as soon as an LED burns out being at 4.5W you still have your inline resistor which will in most cases give out as well, and if it doesent it takes you from your potential 12W down to 7.5W of resistance which causes a fault an d aresitor overload and burns out So basically you need to add a resistor or short the sensor and you wont get the warning

From how it was explained to me from 42DD, it was a voltage problem. It sounds to me now that they may not even be looking in the right place then!
ON a side note, I always wondered why we were the only country with daytime running lights. I didn't realize the rest of the world shipped it due to fuel consumption:

Yeah it is fairly simple, You will need a volt meter and a bit of math. Take the volt meter and put it into the Resistance mode to read the resistance in Ohms. once you get that, do the same for LED. Subtract the two resistances so lets say the original blub is 12ohms and the LED's are 6ohms the resistor size will be 6ohms and it will hook up to the positive end of the bulb which will increase the overall resistance of the bulb which will equal to no Faults Enjoy +Wire-------(resistor)-------wire to + end of bulb--------(Bulb)------Negative wire
