Lane Keep Assist
Has anyone found a solution to turn this off "permanently" ?? like a fuse, reprogram or module. There were modules for the older models? anyone have experience with this. I dont like this feature.

Agree that it's a safety hazard. Really bizarre that mercedes designed this feature so poorly. I always try to turn it off but occasionally forget and it always startles me when my truck suddenly brakes and steers itself with no warning.

I don't like it either. The easiest solution is to get into the habit of turning LKA off at startup. I'm surprised that there isn't an option to simply turn this feature off

Isnt it smooth auto start stop in the signals like the BMW ?
#7
Plus people have reported issues with the car turning off randomly that seems to be tied to the auto start stop being activated.

I find both LKA and ECO start/stop annoying, which is why I disable both. Not only the behavior of both, but that both always default to the active state each time the car is started. Some drivers may like them, but both should be selectable permanently as on or off. Imagine if the entertainment system always defaulted to playing German polka music every time you started the car.

I don't like the engine turning off potentially at every stop. The wear and tear on the engine is not worth the likely minuscule savings in gas mileage.

I drive a BMW Z4 m40i 2020 and the auto start stop is super super well built.
You don't even feel like when it stops and when it starts.

No doubt effort has been put into making this on/off as smooth and imperceptible as possible, and it's probably fine when in bumper-to-bumper stop-and-go expressway traffic. I find it jerky and latent when used at intersections and when making left-hand turns across oncoming traffic. The size of the battery in cars with this "feature" is nearly double the weight of a conventional battery, weighing in at about 27 kg.

I told them a couple months ago that an OBDII device that would kill the ECO start/stop and LKA systems would sell like warm doughnuts.

The module is the one integral with the headlight switch that contains the LKA enable/disable button and red indicator light. I yanked the module out and added a microcontroller device that I programmed and wired in. Whenever the red LKA light comes on, the microcontroller asserts the equivalent of manually pressing the button for 3 seconds, thus disabling LKA every time the vehicle is started. I did this modification 2 years ago to my '19 G550 and it's worked flawlessly. I also did the mod for one other forum member. The tough part is getting the switch module removed from the dash because it uses some funky plastic spring clips that are easy to break. If you think you're able to get the module out and send it to me, I'll do the mod for you.

As you can imagine, it takes only a few lines of code to do the job. I used a PIC10F322 microcontroller, and even this device is an overkill for the task. PM me if you would like me to share my notes about where to make connections.

same piece of tape is still working and does not disable anything except LKA

This is the way these options should work, but don't. The auto start/stop active on vehicle startup is an EPA compliance issue from what I understand, and is why the vehicle always defaults to Comfort. There's no excuse for LKA active on vehicle startup except maybe MB is collecting data on its behavior and efficacy. Still waiting for someone to comment on how it works on black ice.

EU has regulations for LKA where it's required to be enabled on vehicle start. Not sure if NHTSA has the same rules but if not we are probably seeing a case of "implement it for the most restrictive market". I agree though that it's annoying and even dangerous at times. I always turn it off but every once in a while I forget to and then get a shot of adrenaline when the feature kicks in and scares the sh*t out of me...

I don't think LKA is mandated by the NHTSA here in the U.S. In fact, several ADAS systems are being reviewed by the NHTSA in the wake of car crashes to see if systems such as LKA contributed to, failed to prevent, or were not related to the crashes. My '22 X7's Driver Assistance Pro Package (which provides LKA) is an option, and it allows for several of the ADAS functions to be individually disabled (which I've done for LKA). The X7 also has "steering assist" whose purpose is similar to LKA, but its behavior is much different. Instead of a sensation of rebounding violently off a concrete barrier, steering assist keeps the car centered in the lane, almost like a magnet. It works nicely with the adaptive cruise control, especially on interstates in disrepair.

On my 2021 c43 sedan I can just click the LKAS/steering buttons when the car is on, turn the car off, and it will stay off until I click the LKAS button again, doesn’t turn on after the next start like the auto start/stop system. Not sure why the g wagon or any other model would be different
