I have this exact problem, with a 2004 325Ci and 5 speed. I've found that it occurs mostly in 3rd-5th gears, engine at operating temperature and throttle at ~50-80%.

It does not occur when the engine is cold. It does not occur if I'm light into the throttle. It does not occur at WOT.

I suspected the DISA, unplugged it, no change.

Question: Can you log timing data with PA Soft, if not, what software is recommended? Also, what's involved in remapping the DME?

“The test of the machine is the satisfaction it gives you. There isn't any other test. If the machine produces tranquility it's right. If it disturbs you it's wrong until either the machine or your mind is changed.”
