Audi A6 (2005) HID bulb replacement (D2S)
Just replaced the HID bulb on my A6 so thought I’d let you guys know how to do it.
Firstly – when it comes to car DIY I am a novice at best…. My passenger side HID bulb popped so went to Audi to get it replaced. “No problem sir…. The bulb will cost you £120 + labour to fit” I will rather not post what my reply was and decided to give this a go myself.
Anyway – long story short – googled D2S and found a D2S OEM Phillips bulb, strength 4300, and found one for £30 including postage (from HID Origin).
Procedure (should take no more that 15 minutes) – this is my own experience so if someone wants to update any procedures please feel welcome. BTW the replacement was on the passenger side which is easier than the driver’s side.
Tools needed – (Only a small flashlight & small spanner to disconnect batter - sorry cant remember which size).
1. Disconnect battery
2. Remove rear cover on light unit – space is pretty tight but not too hard – only need to unclip the 2 plastic clips on the top
3. Gently turn HID ignitor (I think this is what it is called) anticlockwise – about a quarter turn (instructions are actually on the unit!!)
4. Now.,.. this is where I messed up a bit
– The unit is connected to a wire so I thought I would let this “hang” while is replaced the bulb. Don’t! It is quite heavy so disconnected from the wire and dropped into the engine bay. Had to partly remove the plastic cover underneath the car to get it again – only an extra 10 minutes but can be avoided. So, just disconnect the wire immediately and take out the ignitor completely.
5. Next, there are 2 wire clips that keep the bulb in place. You can depress these easily with your fingers.
6. Gently pull the old bulb out. Unfortunately mine really popped and the bulb was broken. I was too lazy to get a hand held vacuum cleaner that could reach in there so decided to just leave the glass inside.
7. Insert the new bulb – do NOT touch the glass part of the bulb. I was not sure how to align this so I gently slid the bulb in and turned it slowly until is “clicked” don’t think there was an actual click but it just felt flush / solid.
8. connect the 2 wire clips back that holds the bulb in place.
9. then re-fit the ignitor – there are 4 slots to align which makes this easy
10. re-connect the electrical wire – very easy again as this just clips into the ignitor.
11. before replacing the light cover I re-connected the battery to check if the light was working – JOY – it was.
12. replace light cover
13. done – utter another few compliments to the stealers at Audi
all in all you can do this leisurely within half an hour while having a coffee and smoke wile you do it.
If you really put your mind to it – 10 – 15 minutes tops.
Hope this helps any of you guys out there and save £120 in the process….

Hi - no MMI weirdness - It did not even drop my stored addresses in the sat nav (I just disconnected the (-) terminal). I was worried about this as well so I bought a very cheap fault code reader just in case (cost £20).
I used this to reset all the fault codes prior to fitting the light bulb (there were a few as my car has a battery drain which I have still not been able to sort out).These were mostly may fault as I disconnected battery and tested every fuse with a test light to try and find the drain - resulted in aboutn 10 fault codes so I would not recommend this! Anyway, I cleared all the codes before the bulb install and afterwards there was only one code for low battery which I cleared.
That said, the traction control light did come on the first time I started the car. I took it for a drive around the block and simply swithched the traction control on and off - done. Traction control light on the dash has gone out. I ran the diagnostic tool again and no fault codes.
I would really recommend getting on of these diag tools - for £20 you cant go wrong. This is what it is called "U281 VAG VW Audi Seat Skoda CAN Fault Code Reader". It did not have all the fault codes in the manual, but a quick google sorts that out.
