So, is it possibly accessible from underneath? Did you have problem
with it? Did you do an engine swap on a OM603? I know you did the
107.
IIRC, (not likely at this point) it's near the 4:00 to 5:00 position when
looking from the front of the engine towards the rear - on the engine side
of the bell housing mounting plate.

Working on the 107 brakes first.

without taking out the trans? I don't remember ever seeing anything like
that on a diesel. Why would that cause the lights inside the car to flash
off and on? I could see idle speed and tach funkiness being caused there.

connector behind the engine, as the sensor is on the transmission housing.
The sensor at the front is only for setting injection timing.
