My Dealer has me scared beyond reason that if I dink around w/non Audi OEM Accessories or dress up Electrical items that I'll be on warpath with main ECU / warning settings and so Audi cannot support me if that happens and anything needs to be covered by Warranty. Basically mixed religion mixed marriages are out, stay pure and you'll be safe. I don't like overload of 'rules'!
SO, I understand the reason for 'yellow' Fog lights, but I'm not likley to need, the aesthetcis are what appeal to me in this case....trying to have similar color /brightness to headlights. You note about HID at 35W or less ...what happens if I can find a Xenon Kit, any guidleiness that will keep me from setting off warnings which you might have knowledge / heard of? Like you note for HID's, stay below 35W...w/Xenon is there same or additional guideline?

Read the following on other site re minor change 335 - "....a fog-light delete for engine/brake cooling purposes on the coupes, ...". http://www.carthrottle.com/coming-so...ing-bmw-335is/
Re A4 / S4, (I know that Xenon's are not optimum solution for Foglights) but struck me as curious that Audi have Xenon Foglight Accessory for A4 BUT when I asked for the same on S4 I was told that they 'can't be fitted,...sorry'. I doubted the 'will not fit' story and thought 'maybe' something to do w/current draw, loading on the S4's electrics, but have never received clear answer when I ask for 'detail' :-(
Reading the above comment, any people on thread knowledable enough to support logic that in fact yes foglights may get in way of cooling of the hotter S4 under certain driving conditions. Have seen someone elses pics of fitting new halogens and they did show one of the lights is close / in front of part of radiator ............ am I searching too hard for reasons here?;-) [Really want 'same / similar color fogs as the headlights, that's it plain and simple, don't have much need for fogs 'in fog' per say].

BMW deleted the fogs in order to extend the radiator farther to the sides in order to increase cooling. Our radiators for both the Intercoolers and engine stop at the edges of the center opening above and below the centerline. In back of the driver's side foglamp housing is the oil cooler for the transmission, so putting something slightly larger (if it even would be, I doubt) won't matter a lot here, the passenger's side is totally solid and doesn't conduct any air or cooling anyway.
I don't buy the cooling angle for our cars.

No prob 
Not sure why they don't do or "allow" it, it's certainly not a concern of strain on the electrical system, an additional 20 watts per fog lamp is nothing really. It may have more to do with (like Eurocode's) the wiring harness to allow the Xeon is totally different for the A4 setup, so it would need either some wire splicing or an adapter to retrofit it to the S4.

On to Audi Marketing to gripe that I want lofical / technical explanation :-( ;-)

Eventually Dealer explained something that at last makes some sense, though it could be that it's not the last word. Japan B8 S4's all have Proximity Sensors on front and rear bumber (w/reverse camera). Using Xenon Foglight kit, available to A4's without the Proximity Sensor option, the Xenon 'exciter' unit has to be placed close by, because of standard 'short' harness. The proximity of exciter it seems plays havoc w/Proximity Sensors ..noise feedback & whatever. Separately, the harnesses to exciter is required to handle 20KVolts - spike I presume - and 'supposedly'(??) it's not a simple question of splicing & adding a 'typical automotive wire guage' extension. Re latter comment, I have to believe it is technically possible just that Audi don't want to muck around w/std Accessory kit in case of damaging product liability? Would be interested to hear from anyone who 'does' have proximity sensors and yet changed to Xenon Fog's withiout problems associated w/Proximity Sensor performance arising?

Thank you! Here's a few more. I was going to "edit" out the license place, but I thought, who cares. Plus, it's hard to see the look of the LED plate lights if I "f" it up but editing it.
Plus, at night it's harder to see the dirt. haha
On an unrelated note, I haven't noticed very many other brilliant reds out there. Any one else have brilliant red, the fastest color? lol
On ANOTHER unrelated note. I took these with my new Canon T1i. I'm still working out how to use it. I'm NOT a photographer, I just like cool stuff and this camera is VERY cool.
