Ok I'm stumped on this one so I figured I'd see if anyone has any thoughts on this issue- I've got a '98 Z3 1.9 that has a stalling problem.

The car starts up no problem and sounds fine, no strange noises at all, but after 1-2 seconds the RPM gauge shuts off and the idle starts to wander all over the place, then the car dies with a check engine light illuminated. P0340 code on my code reader- ok fine that's a common thing, the camshaft position sensor failing would cause the RPM gauge to die this should be an easy fix. I replaced the camshaft A position sensor, but the problem still remains. I even bought a second sensor to see if that would work, and replaced the idle control valve as well since it had been a little unstable before the stalling issue. Nothing.

The car still does the exact same thing only now it doesn't display any codes on my code reader, despite the check engine light being on. I can't get the car to run for more than a few seconds and not sure what else it could be

Stalling with no codes, I’d look towards problems with the fuel pump or coil pack.
Good luck getting to the bottom of it.
