2010 650i Problem...I think

[Ryrybk]

Idle at 500 vibrates the car a little to notice at a stop in drive. When I rev in very gently while in park it hesitates and the rpm goes down then up which I also noticed when it does that the interior lights flicker.

When I stomp on it at a dead stop it hesitates really badly like the traction control is on but ive tried it on and off. Also I do the pulls in sport mode and slap the shifter over into sport. Tough shifts sometimes but think that’s normal cause of the adaptive learning system trying to learn how I drive.

Just did a fresh oil change cause I bought the car a couple days ago she’s at 81,000 miles so I was thinking maybe coil packs soon. The Carfax had no record of transmission service so maybe even a transmission fluid flush and change. Advise is appreciated since I’ve never owned a 6 series before

Oh and I don’t have any engine lights or codes yet that pop up on the dash or iDrive
