Problem solved! Changing the ECU/DME fixed the problem. However, also the throttle body was defective as two of the gears where clearly missing a tooth:
I bought a kit consisting of a second hand DME and corresponding EWS + ring antenna + key. This is a drop in replacement and was useful to...
My Z4 E85 3.0 from 2003 has currently some issues showing a rough idling which makes it impossible to drive te car. The throttle body has already been replaced (without solving the issue) and one of the other suspects is the DME / ECU. Following advice of some fellow forum members and a Z3/Z4...

I was specifically looking for a 3 liter E85 with manual transmission and hardtop. Didn't know back then there was a Maldives blue Z4 as you don't see them that often, but I really...
My E85 pre-facelift was equipped with the standard manual heated seats. When driving longer distances my lower back always started to hurt. Besides, when driving more sporty in the corners you clearly notice the lack of lateral support (especially for the passenger).
The Z4M seats are very hard...
