S211 Parktronic module location - help please

[prprandall51]

Hi everyone, I would be grateful if someone could tell me the location of the Parktronic control module on a S211 E Class estate?

Since some particularly heavy rainfall two weeks ago, the entire Parktronic system has been intermittently dropping out. I am guessing the control unit my be a bit soggy and I want to check before heading off to the dealer.

Thanks
Philip

It's behind the nearside rear wheelarch interior trim, where the nav unit is if you have that option. #10 in the picture.

Have you been pressure-washing the wheelarches?

Hi Troon, thanks for replying - and for the info.

No, I don't wash the car at all - but the problem kicked off shortly after it came back from the dealer having had
1) New rear shocks
2) a thorough clean - no doubt by pressure washer.

When you say the rear wheel arch - is it accessed from inside the car or outside?

thanks
Philip

Inside. Push the big button on the trim under the rear side window and the whole side trim panel comes away, hinged at the bottom. The electronics are behind the insulation you're now faced with.

The pressure washer suggestion is because the flappy vents are around there, and it's not too hard to force water in.
