W220 bumper proximity sensors
I've had both of our W220's giving false annoying readings. On one car
it's the front right sensor that comes on and stays on at any speed. On the other it's the left rear coming on when the car is in reverse.
Knowing that these are sensitive to fuse positions etc I decided to reset the fuse. According to my fuse chart the sensors are controlled by F75 and F80. F75 is shown in the driver's side dash board panel (I assume this controls the front sensors) and F80 is in the panel under the passenger side rear seat.
Using a piece of plastic to avoid marring the dash side I removed the indicated panel and found nothing - no fuses and no panel. Can someone tell me where I can find F80 to reset it?

in the for-what's-worth department, I get periodic false alarms on my left front bumper. I have traced it to a specific sensor that happens to be quite sensitive *IF* it's pushed into the bumper even a tiny bit. Car washes, maintenance, etc., affect it. I suggest taking a very stiff card - like a double-thick business card - and trying to work each sensor out further from the bumper by sliding the card around the sensor and gently pulling it out. I know it sounds strange and impossible, but you may be surprised at how much movement *may* be in each sensor. On my car, if they are pushed in, even a little, they will give a false reading. I simply run my fingernail or a b-card around the sensor to shimmy it out and the false signals disappear.
