I'm at a loss on what might be going on with my 328xi. Over the past couple of months, when I would make a sharp turn into my driveway the engine would start to bog down and run rough, even after centering the steering wheel and putting the transmission into park/neutral. When I turned the ignition off, the engine would stop with a dramatic clunk that felt like the car was jerking forward. I did notice yesterday when I was trying to induce the issue that the front wheels definitely slip at high steering angles/low speed as well. No transmission/transfer case codes are currently present.

Other than this scenario, the car runs and drives fine at the moment. I've done a bunch of work to the car over the past few months so I'm not sure if this is related to something I did or just a brand new issue. I haven't been able to come up with a failure that would cause this symptom pattern, especially given that it continues with the transmission in neutral. The car doesn't creep forward when in neutral so that makes me think the wheels are properly disconnected from the engine.

Stuff that's been done to the car recently-
-Transfer case fluid change and new actuator motor - the part from Amazon, entirely possible it's bad but I don't know why it would cause these symptoms.
-New water pump, thermostat, radiator, hoses- only reason I mention this is because it involved moving the power steering lines out of the way for access

The car has ~103,000 miles on it so it's a little overdue for a transmission service, I plan to do the front diff fluid at the same time, but again I don't know why something diff/transmission related would cause the engine to bog down in neutral.

Any ideas here?

My guess is one or both of your engine mount


Judging by how the shaking got increasingly worse and now it's shaking even at low speed.

That was my same symptoms

Interesting idea. Hadn't considered that but the mounts could definitely be shot and could cause some weird drive line deflection when steering.

Not 100% sure just fyi lol. I think it may be the control atms too.

My busted control arm made my car move when i drove past 80 mph which is how i realized
