Coding Options

[Degenatron]

If this was in response to my comment. I’m aware of how the matrix headlight functions. If you check the quoted comment, there was specifically a comment about start up animations (light patterns etc) that were not exclusive to the non tinted Matrix headlights, and only to the tinted and blue. I was checking on this point as I’d never heard that before.

The standard matrix light, tinted and blue all have the same startup 'sequence' if you can call it that - a glow from the centre to the outside, very subtle and you wouldn't notice it unless you knew about it: see video on the configurator

The rear light bar is different however and the tinted & blue versions turn on from the centre outwards and the reverse on shutdown:

^This option I imagine is just software locked as the light strips only differ cosmetically, unlikely to be different electronics? We will know for sure once somebody is bothered to dive into PPE programming - needs to be some kind of cost benefit....
e.g. Off-topic but like J1.1 tuning was: Taycan 4 raised from 475 to 730bhp! Insane, only a matter of time before we get a dude like this work their magic on PPE cars:

The point of the Matrix lights is that it selectively dims the lights only in the direction of other cars in front of you, so you can keep the headlights on all the time. Unfortunately, the US regulators require a dimming response time that's fast enough that no current system on the market can meet it. (This demand is much faster than a human could respond, and it's much faster than other markets, like Europe, or apparently, Canada.)

There are a number of vehicles available in the US that have Adaptive Driving Beam headlights. It’s quite possible to meet the timing requirements.

@TS23 no my comments were to jwatte - discussing my opinion that matrix lights are incredible, and my experience with them specifically in relation to his comment about the DOT requiring detection and switching to dip the lights so quick that it was not possible with any current system - my feedback was (implied) it was fast enough because no one has blinked lights back at me and the location of the sensor and lights was probably the main driver who the (on paper) slow response time to dip the lights was probably not really an issue because of the physical placement of sensor and light.

I assumed you knew exactly how matrix worked - this discussion you are referencing is to further then narrative that the DOT should approve the lights for the American market, as they do in fact work great with no negative feedback in the Canadian market.

You're kidding right? You'll need addressable LEDs and a controller to do any sort of animation.
It's a 1K option.
Don't see anything you can code on the Macan, it's all hardware changes.
I can't even read a single controller of it (except for the CAN Gateway) using Car Scanner, let alone code anything. Out of all the data maybe a handful work, rest are gibberish.
From experience VAGs (VCDS), BMWs (ENET cable + software), you can practically do anything (last few years you can even download apps and do preset coding with zero experience), Porsche is the worst I've seen, can't do anything without OEM-level PIWIS

Not kidding. Historically, VAG parts with cosmetic difference are usually just the last letter different. If the hardware is different then the last 3 digits would be different. This goes back as far as I can remember e.g mk1 TT sharing Golf mk4 parts. AI summary of this here but lets work through a practical example below.

E.g. Take the front headlights and the difference between matrix & non-matrix - a definite hardware difference and gives different last 3 digits in the part numbers. Note the 'B' denotes a 2nd revision updated part:

Similarly lets look again at the matrix side lights and non-matrix side lights, they are subtly different: wider vertical spacing on the matrix lights - hard to spot but its there. A hardware difference, not just colour:

Then consider the rear light bar, all the same numbers except the last letter. Same hardware but just a cosmetic difference - I would bet my 2nd pension fund that light bar animation can be programmed!

Regarding the coding, it may come at some point if anyone is bothered to dive into it.
Or we might at least get a diagnostics tool that can be used with a cheap BMW ENET cable, e.g. J1 Taycan/Etron GT got MapEV diag:

I would love to get this light up seq for the tail lights:

That's not true, a different last letter can mean different revisions, different markets, different features all equaling different hardware.
Have a look here:
https://www.eurospares.co.uk/Porsch...ight_reflector_Additional_brake_light?ref=003

Example from above link:
95C945070BD
REAR LIGHT CENTER LIGHT STRIP INCLUDED ADDITIONAL BRAKE LIGHT
P8VG (LED rear combination lamp)
PAV0 (Driving on the left)
from £1,094.83

95C945070BG
REAR LIGHT CENTER LIGHT STRIP INCLUDED ADDITIONAL BRAKE LIGHT
P8VQ (LED rear combination lamp, variable lighting functions, special styling)
PAV0 (Driving on the left)
from £1,468.35

Animated light strips are 400 quid dearer as they contain different electronics (guessing more led segments, led driver has more channels, controller more complex, different command set, different ICs, who knows without opening them up, or having the diagrams for them)

Even if light bars were the same (which they are not) you would still run into other issues:
1) BCM hardware could be different
2) BCM software could be different
3) Feature tied to order may be encrypted
4) etc.

I just don't want Macan users to get their hopes up (I mean who wouldn't want a cool animation for free when locking/unlocking their Macan, not 1K cool but definitely a couple of quid cool).
Happy to be proven wrong/correct.

AFAIK : coding is soo locked down that even the very people at the dealership need to get permission from porsche. All coding is now encrypted and needs to be decrypted and approved on the server level (Germany) I was told. Nothing you can do locally anymore unless you find a way to crack the encryption code. it seems all needs to be signed by porsche before it gets sent coded to to your car.

This is not good news for those of us that want to tweak some stuff....
At the same time, I can understand why they worked so hard to lock it down. Its new software and it needs to be secure. Too bad if it's this locked down, I guess we will have to see what the future holds in this area.

 

[MaccyT]

According to " my guy" who has been coding cars for like the past 15 years. It's currently not possible on the latest and greatest VAG cars anymore. Everything after like august 2024 or the new PPE platform for that matter are all fully encrypted and you need official dealer access to a system in Germany indeed to decrypt, recode, encrypt again. He does not have a single example of someone who got that arranged for whatever reason. So I would not count on it in the near future.

Besides that, Porsche also seems the most conservative brand of them all (compared to the other VAG brands). Software updates are rare let alone software changes/upgrades on functionality.

I'm still hoping that the passenger display get's the opportunity to have it's own headset connected but my dealer told me it's probably not going to happen for current cars and builds.

 

[PrudentOcean]

Let’s not forget that the reason the Macan ICE was discontinued in Europe is that the platform doesn’t meet the cybersecurity regulations and could not be updated to support the encryption standard required by it, making it illegal to offer the vehicle for sale.

The PPE platform on the other hand meets the requirements, leading to our predicament…

 

[jwatte]

I can't even read a single controller of it (except for the CAN Gateway) using Car Scanner,

Yes, the PPE platform uses CARIAD 1.3, which is largely a vehicle ethernet communications system, not a CAN bus based one. And because they don't need the CAN bus for mandatory emissions testing, there's very little there.

I was very sad when I realized I couldn't make adaptive underbody lighting -- no automatic turn blinking, brake red blink, or acceleration zooming animations :-(

 

[pm4s]

Yes, the PPE platform uses CARIAD 1.3

AFAIK the version number did not change from E3 1.2
- E3 1.1 was the infamous (released buggy) I.D software my ID.3 runs (MEB cars)
- E3 1.2 was supposed to be an SDV "lite" software for the PPE platform which they later abandoned any SDV visions they had (18 month delay) and we ended up with the mess the Macan software is
- E3 2.0 was supposed to be the "full" SDV software that Tesla/iX3/etc. run but that also got abandoned with VAG admitting defeat and subcontracting
Xpeng for China market
Rivian for the other markets

 

[jwatte]

Entrenched OEMs with solidified management fiefdoms really are the worst!
