Engine Remote Start

[inkirby]

nice finding, I will try this, as i also lost window and trunk functionality. 

Another question, after remote starting is it mandadory to restart the engine or is there another way that the car "recognises the key" and driving abilities are unlocked? 

Because switching off and starting again the engine is a bit unlikely as it is already running. 

Thanks!

AFAIK, it is mandatory even for other car brands to do “starting” the engine again to put it into driving mode.

Mine is T8 so starting the car by pressing brake pedal and turning the staring knob to drive is seamless when the HV battery has enough power, but have not tried to do ERS when it is low on battery yet.

The key start works on my XC40, I haven't lost any functions, the windows work with the key, the tailgate works without any problems.

I have 045-02

Just to confirm your configuration:
45 - 02
50 - 05
276 - 10

My xc40 2021 Sensus also works only with changes for 276.
But it lost buttons functionality as mentioned before (Windows and Trunk control)

yes, I have these settings

Small updates here:

Currently, ERS works with no issues or limitations.
The key fob works flawlessly as well.

Configuration:
45 - key + phone app
50 - Police
276 - VIP

And one thing that I've noticed. If you'll write those configs to the car in one go — a key fob loses windows and trunk functionality.
But when you update 275 config first, and then update 45 — all should work well, including key fob functions.

Seems like 276 configs could have some influence on a windows and trunk functionality (maybe for the police type it's expected to be disabled). And by updating 45 — you update those functions back.

I'm not sure if that will resolve all the issues for the rest of cars, but I've tried it a few times and every time it worked for me in this way.

Furthermore, ERS could not work right after the configs update. But if you'll press the lock button twice and hold — you should see either the actual engine start, or the "engine check" icon flashing one or two times. For me, that was an indication that EMS functionality is working. After a few minutes, you should be able to start a car remotely.

I'm very happy to report that this method works really well! What I've done:

Set:
050 - 05 (Police)
276 - 11 (VIP thing)
Write the config once

Then set:
045 - 02
and write the config again

Last step: drive over 20kmph to activate the ERS

Now what's works:
- ERS by double pressing lock on key fob and hold on the second press for around 4 seconds
- Cancel ERS by same procedure as ERS but on the unlock button
- Remote tailgate open/close by holding the tailgate button
- Kick activated tailgate

Thank you!
