Parktronic warning tones went beserk
This all occured while sitting still on a small town highway waiting on another driver to pull out of a side street so that I could fit into the turn. (Two cars can't fit going into this street due to a narrow bridge so most everyone politely waits for the car to come out of the side street first). This means that cars were approaching me from behind. It was while the car behind me approached me that the alarms went off. I just wonder if this was just a leftover fault code that had not been tested since my VIM install and it had to go through a reset while in action???
Regardless, I tested it thoroughly after my visit with my sister and brother-in-law, went through several start/stop cycles, etc, etc, and could find absolutely no problems with distronic or parktronic.
The reason I bring this all up is because it raised a question in my mind.
Could someone explain to me where are the rear parktronic sensors in a distronic equipped car??? Is their something that I could check on before taking this to the dealer if it happens again?
Honestly, I think, and I hope, that this is just a fluke.
Similar Parktronic warning/inoperable nonsense has happened to me randomly once w/each of my various '07-'08 S/CLs, w/self-resolution within secs/mins....and no further events....(and no fault codes post-episode detected at dealer on a CL that I soon thereafter took in for the usual 1-3K mi chk)....
Apparently, all kinds of electronic signals in one's environment can randomly trigger these events....
My understanding is Parktronic radars are buried under bumpers on cars w/DistPlus....

Thanks once again

Only once I have had a Distronic plus off warning and that was from a lot of slush covering the grill and the main distronic radar.

The manual states -
!High-frequency sources such as toll stations, speed measuring systems, etc. can cause the Park Assist system to malfunction.
Sometimes when I enter the toll both it goes off, and sometimes it doesn't. I go through the same tollbooth everyday. Haven't figured out why, but it clears itself. One time I suspected it was caused by a vehicle that made it go off every time I got close to it. You might have been in a speed trap.

Seriously - YOU installed it?
Are you a MB mechanic? If so, then I stand corrected.
If not, then uummm, yeah, you shouldn't be too surprised. I wouldn't mess with a car as complicated as this, let alone, the computerized aspects of parkatronic!

I think you're dead on right about this. The town is a speed trap and besides that, the situation was kinda strange where I was at with approaching vehicles from behind (possibly fast enough that the system got quite spooked).

There is a document about radar sensors SW too, you might want to read error codes, a couple ones may appear concerning these control units.

Yes , I did it. It's not a big deal at all. If you can wire up a desktop computer right out of the box, then this is just as easy , if not easier.

I Live in Austin too ( Cedar Creek ).. All of my cars have been modded crazy!!
I actually had one of those VIM devices shipped to me but it ws damaged so I sent it back.
Austin guy what are you driving now??
I would think it would be a major hazard. I am only now entering into the "Benz way of life" (if there is such a thing)... Been a BMW fanatic all my life and never thought I'd go Benz, but I guess things change.
2003 750iL (it's on my profile - to your left
) So, are there any MB car clubs in Austin or any gatherings of MB enthusiasts here? Where is Cedar creek - along Hwy. 21 near Bastrop? Where did you buy your CLK from? MB of Austin was not willing to deal much......

Good. So I'm not the only one. Just one of those electronic glitches I guess.
