The thread is a bit out of date now as there are other solutions and no need to buy A5 leds. Just fit T8rups supplied leds and his resistive plug in loom. Works fine on my facelift 2010 car.
T Jimhread bump....
Bought the A5 LEDs this week, i have an 08 car, fitted them and the work but only stay illuminated for a few seconds before going off again, i don't know if there were any bulb errors before the went off.
Anyone had this issue ?
So after spending hours playing round with my new VCDS lead (Thanks NHN!) I've finally got the bulb warning to turn off in my DIS!
So for all you people who want to try it take a look at this how to!
So first of all after you have ordered your OEM LED's 4H0 943 021 and 4H0 943 022 remove your old lamp units and COMPARE them. You will see that the LED ones have shorter contacts.
Bend the contacts to a straighter alignment so they look similar to this:
Then install them into place. You can use them like this but you will get a DIS warning.

CODING.
I have to thank lala30 for the research he did as i wouldn't have been able to put this together without his research.
So boot up your VCDS and head on over to 09 - Central electrics module.
Check for any fault codes before you start.
Open up the Long coding and then long code helper, make a copy of your long code in paragraph1) (keep it somewhere safe)
Click on byte 17 in paragraph 3)
Right the key here is that if you look at my screen shot i HAVEN'T got Bit 7 (The one you meet to sellect to turn off bulb monitoring), the key here is to ignore the bits and look at the binary box this is where i have got 8 bits (0-7) so turning the first digit to '1' is the equivilant to ticking the bit box '7' (Binary is read backwards and starts at 0)
BEFORE
AFTER
Close the Long code helper and save the code.
After this i turned the ignition off and back on again, turned the lights on andâ¦â¦â¦â¦â¦â¦â¦â¦â¦â¦â¦.. NO BULB WARNINGS!!!
I have a 2012 sport back BE so i don't know if this method will work with all but hey, worth a try in it!!!!!
Thanks again to lala!
