4/ Lane Assist Settings: thanks to tommy95
- Select Module A5 (Driver Assistance) ->

- Select Long Coding ->

- Select Configuration For Lane Departure Warning K15 ->

- Set To Last Setting

4a/ Lane assist systems is a bit annoying that once it is turned off in maxidot menu - assistance systems, it turns back on upon cycling a key.

Thanks to tell @ www.seatcupra.net/forums/threads/obd-modifications.463977/#post-4961854

However this is the coding that prevents this from happening:

-> Control Unit A5 - Driver Assistance
-> select Long coding
-> Select option 0
-> change setting Perso_HC from Activated to Last_setting
or
-> Select option 1
-> Select Byte 13
-> Tick bit 3 and ensure Bit 2 is unticked

Save.

tip: in case you get the error when saving -> (31) function not available, change the mode to vw - diagnostic mode, and try again (even if you are already using this mode, just reselect it again)

Once activated, the car will remember the last state of Lane assist (on or off) upon cycling the key.

5/ Deactivate Stop Start

Disabling Stop Start thanks to Phipilipipp on the seat-leon.de forum
I have seen that some users have problems with this coding on MK3 but It has been confirmed that it works fine on MK4.

- Select Control Unit 08 (Air Conditioning)
- Select Adaptation
- Select Deactivation of Start Stop Function

Please note I have got this code from the German Forum, I also had seen this working on the MK3 and some Audi cars.

Two guys on the Skoda thread say it dont work for them so all I can think is this is Firmware related.

Thanks to @bullionfr on the clubseatleon site

The following coding snippets are from the guys on the Golf Forum or Me looking at what changes are being sold online and or old MK3 Changes and seeing if they will work on the MK4.

There has been some feedback that these changes don,t work when using Control Unit 09 as it requires a security code, The old codes don't work so presume this is SFD Protection doing its job, I will leave them here and once OBD11 have there interface up and running users can try and see if it works.

Further feedback on the Offroad change, Some Golf and Leon users have confirmed it did not work for them others it does so there is obviously more detail needed on Hardware / Software setup to expand on this coding.

If this does not work then you need the following long coding

Control Unit 17 - Dasboard

Select Long Coding

Select either Byte 1 / Bit 3 and tick it or Lap counter to Yes.

Confirmed as working on Golf 8 but not Leon yet.

this is from golf8 so may be different setup on Leon

In 17-Dashboard

go to Adaptions.
Set Offroad to Display
Go to View Activation
Change the setting in View_10 to active.
You should see the following in the View cards.

This is a temporary modification until you recycle the ignition

It is very useful to be able to move the wheels without having the car started at times when we are carrying out a repair, for example, if we run out of battery and the car does not start, to be able to push the car and be able to move the direction.

1 - Select Control unit 44 - (Power steering)
2 - Select Adaptation
3 - Select Activation of pwr steering asst without engine running:

4 - Change value to On (it will reset to off after you recycle the ignition)

and Set to active

I dont know the answer but it looks like massimo23  changed this to View 10 (does not mean it will work on the Leon) but worth a trawl through the view with the offroad set.

Had a quick look through Control unit 17 and i can see under personalization default value attribute Display_Range: which in all the cars I have access to is set to Active but if it is not then change it and see what you get.
