Audi A8 Bulb changing

11 posts in this topic

I'd be interested to know this as well. I had heard it was a bit of a nightmare to do, and after looking under the bonnet it does look nasty.

Almost as if you need to slide the headlight unit out to change them?

I did this:

You'll need a bridge or jack stands to get the cars front up.

After jacking the car up remove the front wheels and remove the inner wheel well ,after that you can see the back side of the headlights and simply remove the lights etc etc....

I've also tried to change the lights from the enginebay but that was horrible...

Are you serious? Is it that difficult to change a headlight bulb on a D3?

I would love to know how much Audi charge for a headlight bulb replacement :o

I'm afraid so.......all in all when using a bridge it doesn't have to take too long...about a half an hour a side...

For the benefit of anyone else who stumbles across this thread when looking for advice on bulb changing... I just changed driver's side (right hand) sidelight bulb in my 2008 A8 4.2L (D3) and can report the following:

Outside lamp units (main beam / dip) look tricky to get at without removing the wheelarch liner as suggested in this post and probably the air filter box as well.

Inside lamp units (DRL / sidelights) you can get to just by removing the air filter box which gives access to a small hatch on the back of the lamp unit held in place by two clips. Air filter box is secured with 5 screws, including one that you need a really long screwdriver to get to. I used a Stanley Yankee extended and locked. Good news is that the screws remain captive in the housing after loosening, so no chance of them disappearing into the bowels of the engine compartment. The hatch is pretty small and the sidelight bulbholder is a tight push fit into the reflector, so a bit of a painful job to do! Bulb is a 501 capless wedge.

No need at all to jack the car up and remove wheel arch linings.

Side lights and full beam bulbs are gotten at by removing the air filter box on the drivers side, and on the passenger side by undoing 4 t30 hex screws and pulling the housing out about an inch t get your hand in past the power sterring reservoir to pop the back housing off. On the passenger side, it appears the dipped bulb can be changed this way too, I'm not sure on the drivers side as I had a local mechanic change them out for me the last time. I'll be tinkering next weekend with my led side lights again and can have a look if you like, and see if I can work out how to do the dips.

Well must say all the threads on A8 side light bulb replacements filled me with horror as I knew the day would come I needed to change a side light. It is very true the engine bay is very tightly packed and yes it not even possible to see behind the head lights....my A8 is a 2006 4.2 TDI and being twin turbo each side is an air-filter and the filter covers are a ABS plastic mouldings that form a top-hat over the filters and block all access to rear of lights both sides but this top hat comes off as it is held on by 5 cross headed screws but they are very deep down the side of this moulding, so you need a very long screwdriver.....these screws are self captive so you not lose them at the front is a moulded rubber duct but that stays in position and then this top hat removes vertically up....not much clearance any side but a little patience and its clear .......underneath is a filter....remove this and now you have total access to the rear of the main beam light where the side light bulb holder is now here was a nice surprise as under this is the power steering header tank which I had never located before.....to re-build is just the reverse....same proceedure for both sides but the power steering is under the near side and now for a joke as before this I phoned my local Audi dealer and he said sorry but to do this job the front bumper needs to come off will need your car for a complete morning ! !

Last time, I did them from above by undoing headlamp bolts and pulling it forward 1".

1" doesn't sound much but was enough to allow my fingers to bend instead of just being useless and straight.

I think there was two torx bolts at the rear low down with big washers.

Maybe 2 out of 4 smaller ones on top too.

My only advice if you are a perfectionist would be to mark the bolt position first or at least take 5 minutes at the start to see how the headlamp is aligned withing the aperture to the panels, as the bolts go into bigger holes so the lamp can go back slightly misaligned.

18 months ago I took my D3 to Audi they originally quoted £90, but then decided that they had a fixed price of £20 for all Sidelight bulb changes !
