Engine doesn't shut off after replacing fuel return hose
Never had shut off problems since buying my 240D eight months ago...
It always shut off promptly upon turning the key. Two days ago I replaced the fuel return hose segments, which had been leaking for some time. Right after doing that, the engine just doesn't shut off any longer after removing the key, it just keep running indefinitely. Even pushing down the shut off lever inside the engine compartment just slows down the engine idle, but it doesn't shut it off. To shut it off I've resorted to putting it in first gear, pushing on the brake pedal and slowly lifting the clutch pedal until eventually the engine dies off. What is going on?

Most likely you nocked a vacuum line loose. Pop the hood and look around.

Ten to one odds that you knocked loose a vacuum connection under the hood. If this is the only vacuum accessory that isn't working, follow the line from the shutoff solenoid on the back of the pump to the firewall, I bet it's freshly cracked or unplugged somewhere.

why would an errant vac hose cause the manual shut off to not work? I'm not familiar with the 240 but still am curious.
reagrds and best of luck solving the prob.

9 out of 10 times the linkage is misadjusted causing the STOP lever not to depress fully at the IP. It's a different problem then the vac shutoff not working.

manual shutoff
When my vacuum pump failed last year due to a quarter-inch hole in the diaphragm, I used the manual shutoff for a while, and found it wouldn't quite shut off unless the manual idle adjustment knob on the dash was all the way down. If that doesn't solve the problem, I guess I would try adjusting the linkages involved.

Seems like there are two distinct problems and both seem easy to rememdy. I'd fix both.
