i could do with one of those aswel.

A word of warning.

After 1.5 years 1 of HID lights stopped warning and is blowing fuse. I opened ballast and it has not been sealed properly so moisture got in and killed it.

I bought a new one from e-bay one of those newer style 2 part ballast that has high voltage part separate and sealed in epoxy. I opened other part and that was not sealed all that well so I resealed it now and it is ready to go in car.

I will also remove the still working one from car, open up to investigate, clean and dry if necessary and reseal to put back.

I am also getting set for A6 and will open and reseal them before putting in car.

I'm looking to replace the yellow sidelight bulb with an LED one, and the halogen main with a HID. I have Bi-Xenon's already, just these two bulbs spoil it with their yellow look.

Does anyone know what the side and main bulb types are, on Xenon Plus?

You should not replace main beams with HID as they must have ability to flash but HID' take time to ignite and frequent turning on/off will wear them out soon that's why they were not HID's in first place

Of course! I forgot about the warm-up time.

I'll get some ice-white items then.

Hi. I run HID 8000k in the seperate Highbeam on my reflector headlamps with Xenon pluss. Those have been installed many years ago and works like a charm and no delay when flashing(do this several times s day due to stupid drivers in front of me). :D

8000k? That must be purple as hell. I'm just going to get ice white halogens.

Do you remember the bulb fitment for the main halogens?

There are 2 types of bulb in the sidelight, but it's really easy to removeone to see what type you have. One is a push fit and the other an off-set bayonet bayonet. There are a couple of threads here on the topic if you run a search. I did the side lights on mine - I'll go look for the link....

Yeah I agree, I'm fed up by that too.

are you "for real" dazarooney? If youre a newbie then let us know more about yourself - I noticed that your signature happens to be a link to "LED Lighting" and we would take a "Dim View" of anyone using this forum as an opportunity to just plug their business! :rolleyes:

If that was a plug for a business, well, the products are grossly overpriced, in fact ludicrously expensive....


Much better and cheaper alternatives out there, its something I had previously been looking into.....

With the exclusion of our spam-happy contributor a page back, can anyone recommend a quality HID upgrade kit for the front fogs on my FL D2 S8?

Don't mind if it's ebay or another source, so long as the kit is ready to install with no messing about!

Should it be possible to fit a front fog kit just by removing the fog plastic surrounds or will the bumper have to come off completely to get to somewhere to mount the ballasts?

I've never taken the bumper off myself and after getting my headlight washers fixed properly I'm not keen on disturbing it!

You should be able to get to somewhere to mount the ballasts without removing the bumper. At worst, you can mount it on the cross-member below the headlights (that's where I put the one for my dip beam conversion)

You can remove fogs without removing bumper, no problem.

I bought these. $32 shipped. Still works perfect after 3 weeks:)

Anyone see a reason not to go with these ones?

http://www.ebay.co.uk/itm/H11-Canbus...item56351d2deb

They're in the UK so no messing about with shipping from abroad....

No picture of the wiring loom, but even the 'decent' looking ones have a couple of crimp terminals to fit into the old plug! Not sure if heatshrink is available with sufficient shrink to cover the entire assembly to keep the plug water tight?

The picture in this listing from the same company suggests they're not bad quality

http://www.ebay.co.uk/itm/H11-35w-UL...item3355848f58

They also do a 50W kit, but that strikes me as overkill?

http://www.ebay.co.uk/itm/H11-50w-Di...item4148d91a19

Not sure if the S8 from our era needs the can-bus friendly ones or if the system isn't sophisticated enough?

i am getting these for a6: http://www.ebay.co.uk/itm/1606281648...ht_5235wt_1163

Do any of these trigger bulb failurenwarnings on the DIS? Because I'm looking to get a 35W 3000k kit for my foglamps.

That's exactly what I'm wondering ref the can-bus diagnostic self check. I suspect the D2 will be happy to find there's a completed circuit there with the lights on, rather than thinking it's an odd value it's receiving. But since the can friendly setups aren't that much more expensive I'm trying to decide whether to go for the cautious option or if I'm just giving myself more components to fail at a later date......

Tempted to 6000K, which I think is a little whiter than OEM bi-xenons?

Been a while since I delved into D2 wiring, but I cant for the life in me remember ever, ever (i mean, ever) seeing any errors for front fogs, yet I know I've seen cars with all manner of broken ones - I'd thus be very very surprised if they are even checked - They're not a mandatory safety requirement like Brakes and headlights and sidelights which do come up on the DIS..

Drop a fog light bulb out altogether, I'm thinking theres a good chance that it wont bat an eyelid.

If thats the case, replace it with pretty much anything you fancy, and as long as it doesnt draw more current than the old bulb blowing the fuse, you should be on a winner... +++

The reason I'm wondering if the non-CAN HID kits will trigger foglamp warning, is because on one of my previous cars, a 2002 Audi A4 Avant Quattro, I did get foglamp warning, when my front bumper was painted to get rid of stone chips, and one of the foglamps wasn't connected.

DIS showed the bulb symbol, and defective driver's foglamp.

not sure the '8 system is as advanced - mine just flashes a bulb at you, but doesn't tell you which one is out! It was only because it kicked in on braking that it gave the game away of where to start looking lol

Not tried pulling the foglight bulb out and the car's tucked away in the garage so not accessible easily to try it before the weekend :(

They do not give warning light on 1997 PF S8 coded beam. I don't think they would on foglights either.

CAN bus friendly kits are not about warning light but about making less electrical noise in power supply to avoid communication errors between different ECU's.

I had a battery failing on mine, would go flat in 3-4 days time and at that time when I switched HID lights on instrument panel would freeze up and CD changer stopped working. After getting new battery everything is fine.

I assume CAN kits have extra smoothing capacitors and maybe filter coils in them to reduce electrical ripple noise in power supply. CAN bus work with faster and weaker signals then older KKL and therefor is more susceptible to noise. On the other hand there is plenty of other things that make noise in the car - alternator, ignition coils, electric motors and even injectors and ECU's are build to cope with it.

I think that if the battery is good and you have good battery connection, ground connections and well generally all electrical connections then non CAN kits should not give any problems either.

can i ask a question may be silly but i use my dipped beam with my day running lights every time im in the car and have done for the last 18 months or more and lately i dont know if its the self leveling or what but the dipped beam seams like its not bright at all any more im finding it hard to see where im going when other cars come towards me, do the hid bulbs wear out after a while ? as in do they progresivly get more dim as they get older, i dare say that the bulbs have been in the car from new at the factory i have never changed a single bulb on my car only to upgrade to led side lights. what do you think ?

also would these be my replacments http://www.ebay.co.uk/itm/Audi-S8-HI...#ht_2316wt_753

I think bulbs can lose some brightness over time but the only way you will compare is to get some replacement bulbs and suck it and see. Unless there is an issue with the Ballast on the HIDs not working properly or the reflectors fading then this is the only other option.

Another thing to bear in mind is that if you are driving another vehicle regularly with even newer/brighter lights then your A8/S8 then it will sometimes feel like your lights have deteriorated when you get out of the newer car into the older one - mine feels like this when I get out of the A7 now and into the A8.

Yes, HID capsules, as they age give out less lumens. I replaced the ones on my S8, as they seemed dim compared to one of my previous cars, an S4. My '98 S8 was also noticeably brighter.

Cost me £19-ish of eBay, and the difference in lumen output is like night and day.

thanks for the help i will buy some of them then they are 6000k not sure about lumins but hopefully will be brighter maybe get some uprated halogens to go with them as the main beam more than likely needs doing as well +++

If I may ask, why would you want to fit 6000k HID capsules? When 4300k ones give out the greater lumen output? There's a reason OEM HID set-up in production cars is 4300k - because it's the best, output-wise.

Unless you just want your lights more blue-ish?

OK, now properly confused by my car! Before ordering anything I decided to take a look at what bulbs are currently fitted, and for both the main beam/flash bulb in my bi-xenons and the front fogs I have an H7 fitting :(

Not a problem, as not ordered any, but wondered if they vary by year of manufacture/light units fitted?

All those following this thread considering ordering - don't buy one of the H11 kits I linked to as they MAY not be what you want!!

ah i see in that case the 4300k will be ordered, im not fussed about how blue the lights are just about how bright they are so i can see where im going better

very handy tells you every bulb for the a8 and s8

Added to favourites - thanks +++

That gives different info to what's fitted on my car for front fogs :(

yea its not perfect as it also dose not pick up having bi xenons only that dipped beam is HID but hey it gives a good reference i guess, i want to upgrade my fogs to led or hid think they are H3 bulbs

i also found a convertion kit for the main beam for those who dont have Bi xenon H7 fitment with Audi Vag harness
