Hmm, your car does seem to have the symptoms associated with a bad accelerator pedal. The DME will slow responses to sudden changes in input when it detects a fault.

Btw, there are two different types of drive-by-wire systems on E46s. One style uses pedal linkage to actuate two potentiometers, the other style is an enclosed pedal. I believe you have the latter, which uses hall sensors, so you need to apply +5V (as the DME does, but you could probably use a little more/less) across pins 5 and 1 and measure voltage at 4, or across 3 and 2 and measure at 6. One output should measure exactly half of the other.
