8V VCDS Mods

DJAlix said:
Not experienced this myself with any of the cars I have done but then I have only ever used VCDS for this function. Are you sure everything has been coded correctly? If your tool has a coding log I would look through it to make sure that no additional / incorrect codings were made by both yourself or the tool.

I've verified everything is programmed correctly and changed the coding to 07006C. I still have the same issue. Every time I test I have to reset the auto up/down on the windows. It doesn't seem to be consistent either. The back windows have always needed reset, but the fronts not all the time. Can this have anything to do with it being a US spec S3? I've seen a thread before where a MK7 user had the same issue, but can not find it now.

Configuring the RLFS as 06A8DD will set the following:

06
  • Bit 1 Rain Light Function Active = Active
  • Bit 2 Rain Closing = Active
  • Bit 3-4 Light Activation Threshold normal

A8
Bits within Byte 1 are currently unlabelled

DD
Need to be plugged in to a car to 100% know but you would be telling the sensor that it's NOT installed within an A3 and is installed against different glass than is used within the A3.

Do you have to trickle charge of run the engine during this time or is the battery ok ?

Just out of interest more than anything.

The issues could be due to a number of reasons really:
  • Hardware Versions of Modules installed within the car
  • Software / Firmware Versions which are installed within the modules
  • Tool used to complete the adaptation and or coding
  • Etc
I have only ever seen Rain Closing work successfully when coded via an original VCDS cable to be honest, and the only issues I have heard of are:
  • Sunroof is not included within the function (Audi branded cars only / personally confirmed)
  • Coming Home / Leaving Home Lights no longer function as expected (Skoda branded cars only so far)
Hard for me to comment further as I have never seen / used the ODBeleven tool but if you can use it to take an autoscan of your car feel free to fire it over to alex@vagcarcoding.com and I will take a look at whats going on :)

Normally I would but I do not have a trickle charger. When I conduct extended coding sessions (for the moment as I am looking for a garage / unit to buy) I use a voltage monitor and when the voltage drops to a point I continue the session with the engine running.

My longest session (coding and adaptation only) has been just over 6 hours with no issues, but this was following some testing where I found that after approx 2 hours of coding (with MMI screen, Radio and DLR's on) the voltage dropped low enough to trigger Electronic Parking Brake errors. Car started fine though :)

Got it... Nicely spec'd car you got there :)

You have the same Hardware and Software revision RLFS as mine so I believe this not to be causing your issues. Looking at your BCM (09) and its software I believe that this is also not the issue as I have activated rain closing on this revision hardware with no issues using VCDS.

I think the problem is due to a bug, software coding error or lack of support at this moment in time within the ODBeleven application.

How would this be corrected with a VCDS cable? Would I simply reprogram with the same settings? Thanks.

Corrected... as in resolve the issues? I am not sure without digging in to things deeper and analysing all of your cars "related" coding. From your AutoScan comment a few posts back I am guessing that you did not take a scan before you started coding? It's possible that while ODBeleven is firing out it's coding changes it is affecting other Bytes, Bits and Channels. Having a "before" scan to reference against the one you sent to me would help to root out any errors. Also, you could just copy and paste your original codings from the before scan in order to return your car back to it's normal state without rain closing.

I did perform an original scan, but did not log it. I wasn't aware you could. So you are saying I may have reprogrammed something unknowingly with no way to determine what? The issue is only seen after operating the auto rain closing, which is not a big deal to me. If a bug pops up some time in the future are dealers able to flash back to stock?

Dealers can flash back to stock as they have access to a database of how your car left the factory. They will probably charge an hour per module.

Lets use another module (5F) as an example of historic programming issues... well the 5F MIB2 unit within VW's. People with Vag Can Professional were trying to perform tweaks on this unit and finding that while their tweak / coding worked they had lost access to bluetooth and or sound control. Problem was that VCP did not know how to 100% talk to this new module and was firing out random code alongside what the user had entered.

What we did to get around and resolve the above was to reference before scans and adaptation maps of the cars in question, and here is were VCDS shines as other tools cannot make adaptation maps... but using Long Coding as an example:
  1. Original 5F Coding: 01730101FF0A000021111101000A00102F00024701000100DE
  2. User Tweaked Coding: 02730101FF0A000021111124000AC0102F00011701011100DE
These are two very different codes. If you started to see issues with the cars systems following the creation of code 2 you could just copy and paste code one (from your auto scan) and then paste it in to your long coding screen, hit Do It and your car is back to how it was :)

Another known coding issue, within the A1 this time, people would activate tear drop wipe for the rear wiper and find that their Auto Lights, HVAC and Front Wipers would no longer work as in the process of coding VCDS, VCP and others was deactivating other Bit's, which was only found by referencing pre-works autoscans.

If your issue is only happening after Activation / Triggering of Rain Closing then that would suggest that something within your car does not like the feature. Hard for me to tell when a tool which is basically unknown to me is being used and not VCDS.
 
A little bit of coding done on my A3 Sline last night. I did the alternating indicator mod, acoustic lock/unlock, added the lap timer function to my dashboard and also changed my start up screen!

In order to code anything within Mag Ride you need the security access codes, which like the ABS module, seem to be unique to each adaptation channel.

I tested this the other day but tying to change the "(1)-Adapting high values-Body height left front wheel house edge" value and the "main" security access code was rejected. Unfortunately we did not have the time available to be able to find codes as scanning from 00000 to 99999 takes approx 4 hours.

I apologize as this may be a stupid question, but does making changes to a modules adaptation settings change the long coding as reported in an autoscan?

Does anyone know if you can display the driving gear on the dash (example D1, D2, etc.). In the US it only displays D or S. The gears are only displayed when in manual mode.

Cannot find any further information on it though, and the site is out of stock :( At £30 it might be worth a punt.

I have found some update about SRT CAN connect.
The cable is a simple cable EL327 USB / RS232. In the specifications is required to read and write both of OBD2 CAN-BUS protocol. To use this cable have to purchase credits and therefore you can connect to their server to perform the coding. Connecting to the server is done through an application after you have logged in with the login that you get after you have purchase credits.
This is what is described on their Russian website :
1000 credits 20 EUR
3000 credits 55 EUR
5000 credits 90 EUR
10000 credits 170 EUR
For activation of ADS you need 2000 credits.
On a Italian site is this confirmed that it works for activation of ADS on a Q3 with MMI RMC.

Adaptations should be separate to long coding. VCDS can create maps / records of adaptation settings and is the only tool I have seen that can so far.

Hi Alex, any chance you will be releasing your new version of your Adaptations & Coding Document? Been a year since your last one... ;)

Not been a year since the last update... I think :)

Will be towards the end of next week. Have been typing all my notes up and working out a new format.

Just completed some testing and due to the applications used and my findings I am gonna post here and not on the Ross-Tech forums as I am sure they might not like competitors being mentioned.

Fired up the current VCDS beta and had a dig around inside the listed Adaptations, found nothing in addition to what has been spoken about within the RT forum thread linked above. Within both the current release and beta versions of VCDS long coding is 100% unlabelled so no further digging around to do within the application.

Known VCDS Adaptations relating to Auto Hold are as follows:
  • AUTO HOLD functionality
  • AUTO HOLD increase threshold; full tensioning force
  • AUTO HOLD increase threshold; reduced tensioning force
  • AUTO HOLD slippage recognition
Fired up ODIS and had a dig around, found nothing Coding related but found the following additional Adaptation - Auto Hold Functional Status - Personalised Settings:

IMG 1087

Interesting.....

Fired up Vag Can Professional and had a dig around, found nothing within Coding as like VCDS nothing is labelled but found the additional Adaptation channel from ODIS:

IMG 1089

So... Looks like Ross-Tech has some development to do as the application seems to be lacking MQB platform wise at this moment in time, and this is not the first "missing" from VCDS item I have found within the past few weeks :(

Kinda... I've had a fast look through my offline data and could not find anything obvious. Will be looking in to it deeper later tonight.
 
Thanks so much for taking a look Alex. That setting seems to be exactly the last step that is missing (in order to make this work without installing the button. I wonder if there is some way to change the setting in VCDS despite it being missing. Guess not.... hmmm

At this moment in time I would say that its not possible with VCDS as the setting in question is an Adaptation and not a Coding.

Have just posted a short "finding" in the RT thread. Might prompt the dev's to dig a bit.

As Mag Ride seems to be becoming popular request wise these days... is there anyone in or around London, with a Mag Ride equipped car, that would be willing to let me perform some security code finding magic in exchange for my coding services? Anything from VCDS to VCP to VIM activation :) Would be a great help to the forum...

Did you have any joy with finding someone for this?
 
I'm in North London most days, and have ordered a car with mag ride. Happy to drop by and let you play once I get it. It'll be a facelift model though...
