Hello.
That sounds good.
It is important that the systems for the TSC work reliably.
Especially at the so-called LZB end, there should not be a sudden forced braking, as with some models.
It's not a bad thing if it takes longer to test, everyone understands that, including me, which will surprise some people.
Test it until it works, I'm looking forward to the 5th series of the 146....
