Rear end is acting like locker

Well friends sweet burnout leads to unhappy car. My rear diff is locked. Severe shudder when turning like a detroit locker feel. Anyone know what happened. I am not sure if i should drive to work tm.

Well i let her cool down a bit and answered my own Qs. Must have gotten hot enough that the LSD expanded causing it to lock more than just 25 to 40 percent. Due to the hundred plus cruise today and low fluid time to seal it up. Ne suggestions on sealing diff are welcome also what fluid and friction modifier required.

Use only the recommended fluids - no extras. Give up burn outs (unless it's a drag car)

OK thanks. Curious about intakes for my 535i would like to get the flapped door air meter out of the picture if possible. And thinking about a chip

That 'flapped door' measures air volume entering the engine. I don't know what is around to replace that measuring device. Mild cam and tune up good place to start.
