Okay, so I am driving over the weekend to take the family camping, and all of a sudden the parktronic on the left hand side goes red and beeps at around 50MPH. First thought bug or dirt over the sensor.

Next day, it happens again. Now they go off ramdomly. Note: ONLY the front.

Does ANYONE know which fuse feeds the paktronic to give it a hard reset?

I had to do this with my S awhile back when it had a dead battery.

Can't help on the fuse but my 2008 has done the same thing 2 or 3 times over the past year or so. It stops it after a day or two. Dealer can't find any codes or anything else wrong.
I was going to find a witch doctor to take the hex off my car but now that someone else has the same issue maybe I won't spend the money and hope someone comes up with a solution.

Dude I swear one day on my 08 GL450 I was at stop light at night on a rainy day and out of no where front Parking sensors beeped for 5 seconds.

There was no body or nothing around it. May be the spell is there on all GL450's after all and I am not the only one .

I had a similar sitaution a month or so ago on my wife 2011 GL350, it was going off on the left front everytime I applied the brakes, I checked to see if it was dirty or covered with bugs, but nothing was impeding it...so I took it to the dealer, and what ended up being the problem was the front liscense plate was bent at a 45 degree angle as my sons bicycle pedal caught the plate and bent it, the parktronic sensor was picking up that bent license plate....I felt pretty silly, but hey, live and learn!

Turns out, it was the middle left sensor went out. Hence it would show collision on the left side every now and again. Dealer wants 2.5 hours to remove front bumper cover I laughed and said a six pack later, I'll have it done in my driveway

Thanks for the inputs guys!!!
