Hello everyone,

I drive a 2020 Skoda Scala that is equipped with the standard Lane Assist system with a non-capacitive steering wheel.
The car also has Front Assist, Cruise Control, an auto-dimming side mirror and an auto-dimming rearview mirror.

Recently I experimented with enabling Adaptive Lane Assist using CarScanner Pro together with an ELM adapter (Vgate iCar Pro 2S: recommended by the developer of Carscanner Pro ELM app). The app offers a restore function that saves the original coding, so I felt comfortable trying it because I expected I could always revert everything back to stock.

After enabling Adaptive Lane Assist and testing it for a while, I was not fully convinced about the behaviour of the system. I therefore used the restore function in the app to return the coding to the original state. At that moment everything seemed to be back to normal.

Later I decided to try Adaptive Lane Assist once more. I enabled it again through the app, but after testing it again I still was not convinced and decided to restore the original coding again. This time I used the newer restore entry that had been saved by the app.

Since then I have encountered a strange situation. The Adaptive Lane Assist menu has disappeared from the infotainment system, but when I drive the car it still behaves as if Adaptive Lane Assist is active. At the same time, in CarScanner the feature is shown as not enabled.

I also tried restoring the oldest restore backup, which is the one that worked correctly when I first rolled everything back, but this did not change anything.

At the moment the situation is therefore the following: the Adaptive Lane Assist menu is no longer visible in the infotainment system, the car still seems to apply adaptive steering behaviour while driving, orange lines on the dashboard and the CarScanner app indicates that Adaptive Lane Assist is not enabled.

Does anyone know what could be happening here?

I would appreciate any suggestions about what I could try next.

Cheers!

Were there any updates to car or scanner between first and second try Adaptive Lane Assist, were car and scan tool device both at good states of battery charge, wi-fi, Bluetooth signals good, ignition on or engine running throughou both occasions until very finish.

Have you tried contacting the developers of the scanners parts and systems or if they have a users forum.

I have zero knowledge of these types but I note on the Vgate iCar Pro 25 webpage it has "Automatic sleep & Wake up wirelessly".

You would get more get more info from the 'Diagnostics & VCDS' section. - https://www.briskoda.net/forums/forum/23-diagnostics-amp-vcds/

Good luck.

Hello Nigel,

Thank you for your response.

No updates were done to the car and scanner between the first and second try. First and second try only were a few hours apart.

I used my iPhone paired with a Vgate iCar Pro 2S adapter. The phone had plenty of battery and the car had just completed a 30-minute motorway drive before I started coding.

When performing the coding, the bonnet was open, the lights were off, the parking brake was engaged, the car was in Park, and the ignition was on.

I also contacted the CarScanner developer and received a short reply stating that “this coding doesn't turn it on or off, it just enables or disables the menu item.”

From that explanation I understand the following: the coding only controls whether the Adaptive Lane Assist option is visible in the infotainment system, while the actual adaptive behaviour is controlled by the setting in the infotainment itself. In other words, the infotainment menu item is what actually switches the adaptive behaviour on or off.

My current theory is that the camera module simply remembers the last active state. If Adaptive Lane Assist is enabled in the infotainment and the coding is then reverted (which removes the menu), the camera may still retain the last state it was set to, in this case 'adaptive mode'. That could explain why the menu disappears after restoring the coding, while the steering behaviour still appears adaptive.

It is not really a problem in practice. When I untick the Adaptive Lane Assist checkbox in the infotainment menu, the system switches back to the normal Lane Assist behaviour. Perhaps on longer motorway drives I might even start to appreciate the adaptive behaviour more, since it does seem to require fewer small steering corrections.

Based on the explanation from the developer, the reasoning above seems plausible to me, but it might also be completely wrong. I am definitely not an expert, so my apologies in advance if my understanding is incorrect ;)

Cheers

That may not automatically mean the car battery is necessarily in a good state of health and charge for various reasons but if there were no signs otherwise we'll take it as the car battery was OK. Always look at the battery voltage on the scanner and whilst things can be done at lower voltages any stuff that is likely to take time to complete you don't want to take any risks.

I follow your logic and it seems a good explanation to me, but like you I'm no expert (in anything).

Personally I would sooner that all drivers didn't have things like adaptive cruise control (I'm not even a fan of traditional cruise control) as it takes away responsibilities from the driver so some of them can fart about with other toys on or in the car instead of paying attention to actually driving. But as always each to their own.

Good luck.

I also use the CarScanner ELM app paired with vGate icar pro BLE scanner but I don't know if iCar pro 2s let you change settings and code in your car. You can just read fault codes and clear them but can't make any changes to a specific module. Let me know further on this
