VCDS Modifications

Ok, so I've pulled together the instructions I followed from the AudiWorld forum post and summarised it for how I enabled Lane Assist on my UK spec A4 with Tech Pack but without Side Assist. I'd strongly advise using a pen and paper to record all the changes you make, so that you can retrace your steps if you go wrong. You will need OBDEleven Pro to make these adaption and coding changes.

This is what I did:

Part 1: Coding Changes

Module A5 (Frt Sens / Drv Assist) - You will be prompted for a Security Code to make changes to the coding in here, use code 20103. OBDeleven helpfully remembers this code if you come back to this module later.

  • Set HC to 'Active'
  • Set EFP to 'Active'

Module 17 (Dash Board)
  • Set Lane Assistant to 'Active'

Module 09 (Central Electrics)
  • Set Heading Control Config to 'heading_control'

Module 44 (Steering Assistance)
  • Set Heading Control Assistant to 'Active'

You will probably have some error / warning lights on the dash by this point. Don't panic - continue on until the end and they should all clear!

Part 2: Adaption Changes

Module 5F (Information Electronics) -

Find 'Car_Function_Adaptations_Gen2' and make the following adaptions within it:
  • Set Menu_display_Lane_departure_warning to 'Activated'
  • Set Menu_display_Lane_Departure_Warning_over_threshold_high to 'Activated'

Find 'Car_Function_List_BAP_Gen2' and make the following adaptions within it:

  • Set LDW_HCA_0x19 to “Activated'
  • Set LDW_HCA_0x19_msg_bus to “Terminal 15”

Module A5 (Frt Sens. Drv. Assist)

  • Set BAP Personalization to “Not Activated”
  • Set Personalization of lane dept. warning Cl. 15 to “Last Setting”
  • Set System mode, lane depart. warn to “Selection via menu”
  • Set Switch-on condition, lane depart. warn. to “On”

You may need to toggle the switch-on condition between 'On' and 'Selection Via Menu' a few times before it activates. On my car nothing appeared to have changed either in the Virtual Cockpit or MMI menus until I switched it all off and left it for 30 minutes. When I next turned on the ignition I could see the lane indicators on the dash, and the MMI menu had appeared under the Driver Aids menu. If you still have error messages displayed on the dash then it's likely you did something wrong, retrace your steps and double check your coding!

From the AudiWorld post there are also some settings to adjust the wheel vibration intensity, warning times and steering effort. I've not tried these yet so I don't know if they work, but I've included them for completeness:

Customisation Settings - Module A5 - Adaptions

Directional stabilization assist driver inact deactiv threshold (3 options)

Directional stab. assist.: intensity: steering wheel vibration (3 options)

Directional stab. assist.: intensity: power steering support (3 options)

I've had Lane Assist enabled for about a month now, and I don't find it too intrusive. If you did want to disable it again you'd need to change some of the settings back using OBDEleven (I'd guess changing Switch-on condition, lane depart. warn. to 'Off' would do it).

Hope that helps, i'll try and help where I can but this is the first time i've had any real experience of modifying anything!

Interesting thread! I have the VAGCOM Hex-Net and have done the following mods to mine so far: -

Locking/Unlocking Beep Enabled
Dynamic Indicators Flash 5x instead of 3x

But on the VAGCOM Hex-Net it does not allow me to do the Lap Timer, Needle Sweep and the above Lane Assist, always freezes on certain steps. So may need to invest in the OBDeleven and get shut of the Hex-Net on eBay!
 
Stupid question but does obd11 allow to clear fault codes. Such as when sensors have been disconnected and what not?

@mjcourtney hey mate I really can't make head nor tail of obdeleven. I've tried following your instructions but I get completely different options on my app.

For the lane assist I don't get option to select ACTIVE. It just says coding or no coding when I tap the HC option in Module A5.

Ive watched all the videos on obdeleven and I still have no idea how to work it! ****** nightmare!

Coded is the equivalent of Enabled/active. Not-coded is the equivalent of disabled/inactive. The terminology isn't very consistent throughout the app. Hope that helps!

Can anybody help?

I was under the impression I had to change bytes and parameters but all I get offered is to select coded or not coded options.
I have obdeleven pro.

So the 'options' your setting to coded/not coded are actually bits that you're setting to 1 or 0 (or enabled / disabled or active / inactive). OBDeleven just calls them different things. So the instruction to set 'HC' to 'active' is the same as setting it to 'Coded'. OBDeleven tries to make the coding / adaptions a little more user friendly by representing the bits as single options - but this can get confusing when following instructions derived from a VCDS procedure.

How far down the coding changes did you get? (Needle Sweep should be an option you can find under the Dashboard module, you'll need to set it to Coded / Active / Enabled depending on what OBDeleven calls it).

@mjcourtney To be honest mate I gave up! I couldn't find needle sweep anywhere but found lap timer. There was also quite a few different lane assist and I didn't know which one.
So am I right in just assuming all I do is select the option I want and just select 'coded'?
I selected Lap timer but it didn't come up on my display.
 
Yep - anything that says set to 'Active' you set to 'Coded' or 'Enabled'. To access the lap timer once activated you'll need to press the left menu button on the steering wheel when on the trip computer screen - you can then select Lap Timer. There should only be one option for 'Lane Assistant' in Module 17 - can you take a photo / screenshot of what OBDeleven is showing you for this module?

Needle Sweep is labelled 'Staging' under Coding in Module 17 - Dashboard. Set it to 'Yes'.

You shouldn't need to change any number parameters - it should all be drop down options to pick.
 
@mjcourtney Ok managed to get Lap timer so far

I've got down to Module A5 as the last step in Lane Assist. When I select BAP Personalization it asks me for a code?!!!

System mode, lane departure warn. asks for a pin code as well?

It should have asked you for that code when setting HC to 'Coded' in the first step, so I'd also go back and check that's been set correctly.

Loving this thread, but, not sure about trying the coding obviously this can be tracked somehow if your car goes for servicing etc and requires some kinda update, will everything be reset again?
The boot timer for me is interesting, bent down to give my dog a markie and the ****** boot opened, that's way too sensitive, am scared now about what touches the key!

thanks mate. I Completely missed the code. I definately don't get asked for a code when I select the HC. This is under the coded section and just gives me the option 'coded' or 'uncoded'
 
So far I've managed to get the needle sweep, lap time, VIM and Sports Computer activated.

Exactly why I increased the time on mine. Not had the problem again since.

Fair enough! Have you completed all the steps now?

So apart from coding, what do you actually need for lane assist your car must have some certain options?
Sorry for any stupid questions #learning
 
you have to have the city pre sense camera behind your rear view mirror. thats it

Thanks to @mjcourtney, I have finally managed to code Lane Assist. It's weird seeing it work for the first time.

So what is the difference between a 55euro odbeleven pro and a 225 gbp rosstech vcds?
The rosstech is limited to 3 vins for that price, can't see any limits on odbeleven.

Which one is safer? Don't want to end up with a black garden ornament if it goes wrong!
 
I've got an odbeleven but I'm not a fan TBH, prefered the VCDS that I used to have (Sold it for £25 quid less than I paid for it last year). I've gone VCP now given no full vcds support yet and so far I'm getting on with it ok.

All be it I've had no need to do any changes yet as @djalex sorted me out on that front.

Not really a modification, but if anyone is wanting to know how much Adblue they have left they can check it with OBDeleven.

Engine - Live Data - search for "Reducing agent tank volume, act.value calculated" for litres remaining, or "sensor for reducing agent fill level, calibrated" for a percentage.

I have the 24 litre tank, I've done 3260 miles since new and I have 15.46L left. Not bad!

I don't know why Audi don't provide a way to check this on the MMI......

There is an MMI menu option that can be activated, via firmware editing only tho

Ah, even more strange that the option is there, but hidden by default! They obviously thought the majority users wouldn't be interested I guess.

I think some cars, depending on equipment level, don't have the related sensor even if they are adblue. Classic Audi penny pinching!

My FL A3 has a hidden oil level mmi menu but no sensor :(

So anyone in Cumbria that can change a couple of things via VCDS/OBD etc. I have the Tech pack and would like to activate the high beam assist and lane change assist (I have forward facing camera), as well as dipping mirror and needle sweep.
 
Couple more useful ones I've discovered whilst tinkering with OBDeleven. Both these tweaks are in module 46 - Central Module Comfort System.

Activate option to enable / disable auto-locking in the MMI (when it locks as you drive off):

5f487c25aafb78a6810ff3496fc5a551.jpg


Coding -> automatic_lock_not_at_mmi set to "not active"

89d24fe32f2fe1bfc4f78213cfa9c49d.jpg


---------------------------

Enable remote locking whilst engine is running (useful for de-icing!)

0dc1930d7dc91f4c1358ec22665a29f8.jpg


Coding -> central_locking_system_lock_unlock_at_engine_running set to "active".

--------------------------

Will keep digging to see what else I can find that might be helpful! :)

This thread needs renaming, very little within it is easily possible with VCDS, should be called "OBDEleven Modifications"
