Hi Everyone,

For the 2nd time in 5 days my 1999 e300 TD will not turn off.

All of the lights flash, you can hear the engine revving and losing power, the digital outputs flash (radio, heater, etc...) and the key is "locked" in.

The only way to get it off is turn leave it in gear and turn it off but the key is still "locked" in. Letting go of the brake will let go of the key.

I found this thread that mentioned a vacuum shut off valve:

1987300sdl will not turn off

Is that what I am experiencing?

Thanks!!
