Thanks Ashman, it seems my 92 400E always starts from the 1st.

I finally found out this from service CDs:

On model 124.034 (400E), to enable the catalytic converter to heat up more rapidly, the 1-2 upshift in the automatic transmission is retarded at a coolant starting temperature<40C as follows:

After a speed of 8 km/h is exceeded for 8-13 s or up to max. 38km/h.

This is controlled by the LH control unit and the 1st gear starting off relay

So they shouldn't call it first gear start relay, it's actaully a upshift delay relay.
99 BMW 540i 6-speed 110K Km
03 SAAB 9-5 wagon 80K Km
92 400E (Sold) 245K km
Still missing the days with the Benz, it kept me busy.
