Video of N62 Engine suffers from a sudden drop followed by a spike!!!
2006 BMW X5 4.8is with 37,000 miles... N62 Engine
After the engine has idled and warmed up from a cold start or sitting for several hours, sometimes there is a sudden drop followed by a spike in the engine rpm as captured in this clip. The spike happens when rpm is being lowered by the computer. No yellow or red lights go off.

The dealer tells me since they can’t duplicate this there is nothing they can do about it. Anyone has experienced this issue??? Any idea what the culprit is?
Thanks a lot,
