Default 2015 S8 Delivered

My brother recently took delivery of a 2015 S8. Glacier White / Black leather interior. Car is obviously super nice. Few quick questions, wondering if there is a most active forum discussing these cars?

Audi GMBH was out touting heavily the new Matrix lights for 2015. Sadly, it doesn't look like these were delivered as functional in the USA. Trying to figure out if that is something that can be enabled by VAG-COM or if there is a separate module / assembly all together. The lights look the same but they don't appear to function the same. Gives me hope that this could be a simple vag-com tweak but don't see too much discussion on the forums regarding the A8/S8 series.

Any thoughts?

Thanks

Drew

The Matrix lights are illegal in the US. Audi and other car manufactures are lobbying NHTSA to change their outdated laws, but so far, no luck.

Yup. Aware of their status in the USA. I'm curious if they can be enabled via vag-com for use on private roads and tracks, of course. I know others have change the behavior of the led signal blinker to work in tandem with the turn signal on other Audi models; wondering if the same can be done on these Matrix setup lights or if there is some more complicated hardware enabling the Matrix function.

Would be great if they could be retroactively enabled if/when the DOT gave Audi the green light, but I doubt that's the case. We also don't get the sequential front/rear turn signals; but that might be an easier fix to achieve---just guessing on that though.

You found it - this is the most active D4 forum I've found anywhere.

In general if a vehicle is FMVSS certified with certain equipment and operational methods, the Ross-Tech team will not discuss how to achieve such changes with VCDS.
That doesn't mean it can't be done, but there are liability reasons and you'd be specifically 'changing' the functionality.

I have yet to look through erWin or PL24, but I suspect there are different part numbers for the non-matrix versions.
If that is the case it would be a moot point...

I'm thinking a few more 2015s will need to be delivered in the USA before there is any real investigation. My understanding was that Audi is looking to get these Matrix lights approved in USA and the hope was that it could be enabled retroactively.

Having a 2015 on order, I really hope your "understanding" is correct. However, I doubt that's the case. The matrix units are available in Europe as an option over the standard LEDs---they cost out at approximately $1400 (US currency equivalent). Can't really believe the way the option is priced that it's merely a software coding issue with no associated hardware/parts: different headlamp units with individual controllers for each LED; different sensors maybe; matrix units do not have a manual hi-beam control, which probably means those cars use a different turn signal stalk; perhaps also different wiring harnesses. If my speculation is correct, then it makes retrofitting an expensive proposition, if it were possible to do it at all. Perhaps that's just me being skeptical, but I'm not confident that it's as easy as you hope it is---but really hope that I'm wrong :-)

Have to think you're probably right. Didn't realize it was an increased option in EU. I didn't see it on the UK configurator. Wishful thinking. Still holding out hopes. Are you specing an A8 or S8?

I agree with this and the rest of your post.
Unfortunately I don't have access to the 2015 parts info... yet...

VAG historically never spends one thin dime extra putting hardware in a vehicle that's disabled in SW.

Would love a parts list / price breakdown when you get it.

There are just too many complexities to the system for Audi to just give us a free ride, especially when it would be a scheduled extra cost option on at least some A8 trims; perhaps standard on others like in the UK.

Matrix system is actually standard in the UK on the A8 Sport Executive, Hybrid and W12 trims, as well as on the S8. An 894 pound option on the SE trims. I still doubt the hardware for it made its way here at this point. I ordered an A8L 4.0T to replace my current 2011 D4 LWB. It's scheduled for production week of 9/15. The order specs are on this thread:

Not sure I agree with all of this and here are my reasons why.

To manufacture two different headlights is going to add cost. I am willing to bet these headlights are exactly the same as the matrix units available in the EU.

Now the cabling behind them might be different but then again it adds cost that I do not think VAG is willing to spend when they could have it programmed into the ECU. Software is already developed and it shouldn't be that hard to disable/remove/reprogram portions of it for cars heading state side.

So I believe everything is in place except the ECU programming of it.

80O pounds (UK) worth of software? Doubt it, but who knows. Hope you're right.

So, after doing some research on the matrix technology/specs, I have to agree with a lot of what Lazydog suggests---the headlight units are probably the same, and the system is entirely software driven with no motors or servos involved. Although not specifically stated in my readings that the technology ties into existing Audi cameras and sensors, the matrix systems utilizes a light sensitive camera to detect oncoming cars' headlights and recognize cars ahead (same camera used by current auto dimming headlight feature?), uses pedestrian and animal detection to cast spotlight beam on them (night vision assit infrared camera?), predicts when to turn on hi-beams outside of metro/suburban areas as well as when to activate side cornering lights before actual steering input (tied into car's navigation system and lane monitoring camera).

If your 2015 A8 has the package with auto dimming headlights, has night vision assist, has lane monitoring, and obviously Navigation, then it might be an issue of plugging in a different control unit and loading the matrix software. But nothing is easy, and the potential problem areas are the manual aspect if the current hi-beam control on the turn signal stalk, as well as the fact that there is no light switch for the matrix headlights whereas our cars' headlights are controlled by that switch. Also, would the wiring harness be different to accommodate a different controller, and are the headlamp units' wiring already prepped to plug into a matrix controller? Perhaps it could be done, or it could be a case of "so close, yet so far". I guess we'll find out in due course.

Not sure my brothers car was spec'd with the night vision assist and I can see where having that would be critical to the overall success of any retrofit.

Forget everything I said in my previous post from earlier this morning---the headlamp units are DIFFERENT (see pics below):

- Audi Matrix headlight units have an upper hi-beam cluster containing 5 individual LED segments (pic #1)
- U.S. spec LED headlight units have a different upper hi-beam cluster with larger reflective segments that contain only 2 LEDs (pic #2). I took this photo this morning in my dealer's showroom.

Draw your own conclusions as to the ability convert U.S. units to matrix.

There are so few of us on the leading edge of the D4 that we simply don't have a lot of answers.
We still haven't figured out an answer to LayDog's other lighting question.

In five years when kids are buying them with shot air suspensions thinking they got a great deal, putting on giant wheels surrounded by rubber band thick tires, and cutting up factory exhausts... by then we should know.

In the interim it would be nice if the DOT/NHTSA/etc would grow a brain and let the technology come here.

Jake- See my post just above yours---The units are different...Confirmed.

Thanks derf, I had high confidence they were.
It's got to be way less expensive to put in 'fixed' LEDs and less vision processing.

The dog decided it was time to take me for a walk before I finished my post !
