Maybe it will help.

Glad it worked for you.

I recently noticed this also on my 2016 Edge. I think I started noticing it after enabling "Secure idle", the feature where you cannot shift out of Park without the key fob (with push button start).

Yes it is possible, at least on some Ford vehicles, not sure on the S-Max. For the 2015-2018 F-150 this is the code:

Secure Idle enable BCM 726-42-01 x1xx xxxx xxxx if engine is running but fob is away from vehicle, vehicle cannot be put into any gear

I am not really an expert in this, but maybe you also need the antenna kit for the single button remote to work.

When you first installed the LEDs, how did you stop the fast flashing? The light out feature works as you described, the indicator in the cluster would flash fast while the exterior and hazard flasher will flash normally.

For an Edge, this is where the language country code is set in the IPC: 720-04-02: **** xx

Check you original ABD data for the IPC and return them to original. You can try one by one to see which one will fix it.
Use this site to get the original ABD values:

Try to disconnect the car's battery for all few minutes.

Suggest you check your ABD and compare it to the stock values for your car and make sure you didn't change anything else by mistake.
