Can't answer your question but I can help you diagnose.

I had the exact same issue with my car. Turns out that when my rear bumper was repainted (by previous owner) they repainted the sensor as well. The paint got too thick which was throwing the sensor off. I had to get a new sensor and have the bumper removed in order to put the new sensor back on. The sensor itself isn't too bad (~$80) but it's more or less the labor of R&I the bumper that will get you (especially with the prices dealers charge). Luckily my aftermarket warranty covered everything except paint for the new sensor.

Was your rear bumper repainted recently?

Seems kind of bull though if CPO doesn't cover the parktronic system. I don't see how that makes any sense, it's a computer system just like anything else on the car and it's not a wear and tear item.

I had false Parktronic warnings on my front left on my 2008 S550.
The dealer replaced two faulty sensors (221-542-04-17) and had them painted under warranty.

That was during the CPO 1 year warranty extension active in year 5, though I also have the MB 2 year/100,000 mile extended warranty which covers years 6 and 7.

Call a different dealer - check your warranty contract and ask your dealer exactly which language excludes your problem.

P.S.
I continued to have the false activations and found they went away when I removed my German front license plate. Apparently the plastic bracket was not keeping the plate flush against the bumper. My SA said the European models do not have Parktronic, just Distronic, but I saw several ther last summer. Maybe I'll get an OEM Euro holder sometime and try again.

Your SA is full of crap. Of course European models have Parktronic. That's why they invented it in the first place, because the parking spaces there are so tight! When I was in Europe, it seemed like 90+% of MBs there have Parktronic, even the really short A Classes.

Was your Euro plate holder not OEM? Maybe that was the issue.

Actually my SA (same since 1999) is really good, but I think he was outside his area of knowledge making that comment about European practices so I forgave him!
My dealership also didn't know about the curved side mirrors that eliminate the blind spot, standard on most European models and which I had to purchase in the UK when i was there - I use them on all my vehicles - very simple but effective upgrade.

My custom plate from www.europeanplates.com came with a plastic license plate holder. They do have manufacturer specific plates now, maybe they are OK.
I didn't spend the time in a parts dept to get an OEM one when i was last over, too busy having fun.

That makes more sense to me.

I assume it's not convenient to put the old bumper back on and see if the problem persists?

Aftermarket bumpers typically don't affect parktronic systems at all. It just depends how good you are with your dealer. If you have good connections with them, it will be no sweat for them to warranty the parktronic. If they just don't want to fix it, then saying you have aftermarket bumpers is a good way to get them out of doing any work.

Thanks for the info HiTach. It's not the first time I've been misinformed from the dealer- usually just have to let it slide.

Actually... My S350 does not have parktronic... I.e it does not have the little potholes. Just the distronic plus sensor and some hiden sensors under the bumper. I think thats what the SA was trying to say.
