Hi,

 

Does anyone know how to fix 'dynamic cornering light error' on skoda octavia? I used OBDEleven to make some adaptations to enable matrix headlight but now it says 'no basic settings'. I did try to copy the old value long coding and validate it but issue is still here!

Is the full matrix led just the standard led's with a software upgrade? I thought the hardware was different.

When changing any coding in 4B module, you need to perform basic settings.

Basic settings for the lights (last error) is just about auto-leveling. You can stop the car on level ground, remove eveything from the trunk if you have anything, and perform basic settings.

As for matrix - do you even have matrix headlights? If so, than:

1. Why did you want to enable them in the first place? If matrix are installed on the car, they are enabled.

2. Have you taken full backup of 4B module prior to coding?

a. If yes, than go to backup, live data and note matrix headlights "horizontal angle reference segment left, in angular minutes" and same for right headlight. Based on that you can run basic settings and provide this data.

b. If not, you are screwed. You need to visit dealership for matrix calibration.

 

If you don't have actualy matrix headlights, just reverse the codings you did, and perform headlights basic settings (again - on level gorund, with empty car).

 

Last error is just indication, that you have used SFD unlock. You can click on SFD in OBD11 and lock the module, error will clear.

 

You need to be careful when coding, as in some cases you may hurt your car, like in this case.

 

ALWAYS take backup of the control module prior to ANY coding!

Hi, in my country, many options are locked from factory, most hardware is there but not enabled so i thought i'd try, as for matrix headlight i have no idea as no info is available as to the 'Style' trim level having it ir not. Can you explain how to perform basic settings? I will try to correct it then, dealership tried but could not fix the problem!!

@Avi1407make a photo of your headlights and we will tell you whether they are matrix or not.

As for instruction, i will need to dig it, but just now leaving for a business trip, so will have limited access to computer.

You can try to look on OBD11 forums in Golf 8 or Golf 7 sections. This is where i found it.

Hi @Avi1407,

For this error can you please raise a ticket with Voltas Support guys? I also encountered the same error when I ran 1-click app from OBD11 apps list store. 

More tickets to be raised, more pressure will be on they shoulders to search and to find a fix for this.

Thank you

Voltas cannot change it, except to warn users.

No matter if it's manual coding or one click app. Whenever something is changed in 4B coding, one need to perform basic settings. It has nothing to do with OBD11, as same thing happens with VCDS or VCP. It's just how controller is working.

But i agree, especially with one click app they should provide instructions on how to get your current settings, and how to perform basic settings (using your old values) after coding.

Ok, makes sense, can you guide me on how to do basic settings to fix this issue please?

@Felix2021, Agree with what you said. A few words in a warning + instructions will save a lot of pain/time for others OR you will think twice before doing any changes in the 4B module.

@Avi1407, In my previous post I was referring to the B17D7F0 DTC from 09 - Central Electrics module. I also encountered the same error when I ran 1-click app from OBD11 apps list store. The DTC is still present on my car too.
So, please please, raise a separate ticket with Voltas Support ONLY for this issue. More tickets to be raised, more pressure will be on they shoulders to search and to find a fix for this.

This tread should help you:

Fixed it using those instructions. Or maybe not fixed per se, because before coding i already knew it will be required (found out by Googling for something else).

Hi, will send you a proper picture of headlights tomorrow, we've been experiencing torrential rain and thunderstorm for two weeks now, so i could not attempt anything on the car, my garage is not on level ground so that's a bummer!

Picture would indeed be good.

ive been there also. lol dont touch stering curve or dynamic AFS lights. this will run errors. Then only solution is skoda service . recalibration lasts up to 3 hours, trust me it s not the same as factory settings.

No. You can backup you calibration settings, and enter them later on, after coding. No need to Skoda service.

Unless you have changed your physical lights position that is

Hi @Felix2021,

Would you be kind to provide some instructions how to do the backup of calibration settings with OBD11 App, please?

Thank you

I have linked topic from OBD11 forums here.

You need to create backup of control module, and than you can find calibration info in "live data" within the backup. Write it down, so later on you can type it in when doing basic settings after the coding.

That's the short version  More details in the link above.

This will work granted you do it PRIOR to any coding, otherwise you will lose calibration data, and this is when dealership visit is indeed needed.

Thx @Felix2021 for your fast reply.

Yes, I get the point to follow the backup procedure prior to do any coding on 4B module. Actually I just want to have the "live data" within the backup for future reference (given the "professionalism" which the dealers give evidence) . I'll not touch the coding on this module since I don't want to fry the basic settings.

In regards to the procedure, I think  you're making reference to:
 

Do you have a backup including the live data or some data inside the live data when offline? If so, search for "Matrix light, calculated offset values" and take note of left and right offsets in angular minutes.

But, I've just checked within my backup did last week and all the offset values are set to 0. Is this because probably I did the backup during the day and the headlights were turned Off?
Shall I try another backup with Low-beam ON?

Br

Edited 13 February, 20233 yr by djmartzian

To be honest i don't know. Was under impression that offset data should be there all the time, but haven't checked really. I always do it in my garage, where anyway lights are turning on automatically.

You can try to backup again with lights on, and let us know.

Hi @Felix2021,

 

I've did a new Backup in this evening with headlights/Low Beam ON. The same apply, all offset values are set to 0. 

I've also checked other parameters, data/values have been recorded for them. 

 

Would you be kind to check your 4B Backup in Offline mode? 

 

Thx

Sorry, you are right.

I also have offset values as 0 in live data.

What you are looking for is "Horizontal angle reference segment left, in angular minutes". And the same for right.

In my case for example it 36 and 24 minutes accordingly.

This is the value you need to provide during basic settings of matrix. I think it shows angle between headlight axis (which might differ slightly depending on how it was installed to the chasis, as there is some adjustment) and camera axis. Based on that computer can calculate which segments to switch off when camera sees a car in particular position.

Thx @Felix2021, as always eager to help. 🙂

 

I've also attached a screenshot with values for the car in the profile, hopefully these values will helm someone with same chassis and trim.

 

Cheers 🍻

In theory each vehicle should have individually calibrated data. So in theory everyone should check their own backup, to get this data.

However your screenshot makes me wonder, if they are really calibrating this in the factory, or if they are providing same data for all? In your case it's identical to mine.

If they provide same data, that could explain why some user complain about being flashed at, and some not. Maybe in some cars these values are simply not correct, and matrix should be properly calibrated, and in others it works ok?
