Any ideas?

What are you using to read the fault codes?
If there's a fault indicated there has to be a code logged, you can't have one without the other!yµ (idµ - eAµ) ψ=mψ

I use a IID-Tool.
But I think sometimes I have two faults, which I always ignore
Lost comm to transmission modul and lost comm to EPB-module.
The flashing light and signals come only occasionally, not always at startup.

I had a similar issue after a handbrake scream the other week. The beeps would go off on startup or whenever the wheels stopped turning (junctions etc).
I however had a C1A00-4B "parking brake control module" fault logged.
The handbrake was disabled whilst the code was logged.
Fix for me was to clear the codes and then pull up on handbrake button and hold for 5 seconds, hold off for 2 seconds, and then hold on for 5 seconds again.

Wow - is this a LR-Routine?
Is worth a try....

Check for "pending faults" it may just be the handbrake switch. (not uncommon) yµ (idµ - eAµ) ψ=mψ

What switch? In Console or a swith in EPB-Module on the rear axle?

Hand brake pull switch beside drivers seat. Check for the codes when the fault appears, or anything that might be "pending" You can select this in the GAP settings. yµ (idµ - eAµ) ψ=mψ

Really? How can I do that?
I've always read the errors from the menu in the app.
Is there a difference to "pending"?

As the PCM and other control modules monitor each system and component they will log faults as either confirmed or pending. This depends on the relative test cycle which differs between systems. If you have selected "pending faults" in your settings menu (status bit flags) these will be displayed. If not you will only see "actual faults" (confirmed) or whatever selections have been made from the list. Drive cycles are relative to some test reports whilst other cycles are used for other systems
Confirmed faults are represented by a joined chain link in the icon field at the top of the screen when a fault is displayed. Pending faults are represented by a broken chain link with a red stripe across the break in the link! It usually tells you the fault is pending if that is the case and has been previously selected!
Select "Faults" > select "Advanced" > "Status bit flags"> select "pending"> (or whatever protocol you want displayed) select "Apply" > select "Save" (I think, from a dwindling memory )
It's all in the manual if you take a look and is easy to set up. yµ (idµ - eAµ) ψ=mψ

Found it!
Flasjhing/Signal does not always occur. I'll read it once the error is there. There is currently nothing in it.

It's a pending fault so and has not occurred on the last test cycle which is why it's not there!
Faulty hand brake switch or possibly the brake light switch. yµ (idµ - eAµ) ψ=mψ
