Solenoids could make a racket like that, there are four or more. Hydraulic Unit The Hydraulic Unit is energized through a relay controlled by the SMG II Control Unit.

Sounds just like his problem. So I guess that means there is no damage to the transmission. It just shifts into neutral to protect itself from potential problems.

When it works ok, does the sound go away when the clutch is activated then come back when the car is in gear?

Its trying to prime and since there was no fluid left in the reservoir it developed air in it. Like John said it is leaking somewhere. Get the car up in the air and look around the front of the driveshaft and all around the lines.

the accident (or more likely the repair) could have caused a leak in the extremely high pressure hydraulics which caused the pump to run dry which caused the pump to not properly disengage the clutch which is probably resulting in the sound you hear (hard to tell) which is probably either the pump trying but not fully disengaging the clutch (bad pump internals or the clutch plate and flywheel grinding or half-engaging)...lots of...

fill it up with clean fluid (if possible do a flush). see what happens. don't know smg. sorry. good luck. thread bump for you. OT FTW, FOT FTMFW

sell SMG and buy real e46 m3. on a side note, GL with the fix...sounds like it's gonna cost a couple mac book pros though
