Silly me, hope that didn't damage my transmission, today I checked the ATF level when engine running, I couldn't see any oil mark on my dip stick, my ATF must be very low.
I poured in about 6.5 Litres ATF, the manual says I should expect 7.7 litres for a 400E, it must miss that 1.2 L.
Thanks a lot.

Still missing the days with the Benz, it kept me busy.
