Poxy Proximity Sensors

I've noticed this happening gradually over the last month or two.
Is there a reset or something for this?

I have however been told time & time again that there is no sensitivity adjustment with Star. On my last 3 cars the Parktronic has been faultless.
However - with Parktronic active, people walking near the car will trigger it as will coming down a steep slope to ground that flattens out in front of you.
Parktronic sensors can be damaged by pointing pressure washers directly at them so be careful.
Rather than one side being over sensitive I would suspect the other side to have a lazy sensor due to damage or obstruction.
Try rebooting the processor by turning the system on & off with the dash cancelling switch. Otherwise pull the negative terminal of the battery. Only trouble with this is then you are going to have to resynch things like sunroof etc.

I do get my car pressure washed by an automatic touch-free wash about once a month. I live in an apartment with no running water in the car park so its easier just to pay the $18 per month. Hopefully that isn't a bad thing for the sensors.

It's more the portable Karcher style pressure washer hand held that can get up really close with very high pressure that will do damage in the wrong hands.


The Jaguar workshop (I bought the car from a non-Benz dealer) couldn't officially diagnose the issue with their diagnostic equipment so I went to a small but licensed Mercedes workshop (very nice people, they have an MB dealers licence but don't sell cars. I'll go to them next time for my service). They diagnosed the fault officially and the warranty company (worth its weight in gold that warranty) is paying it. One more 45 min booking and my new front sensors will be painted and installed.
NOTE: to any Aussies buying a Benz or any car, send me a PM regarding an after-market warranty. The one I bought is truly worth every penny (No I'm not a reseller trying to flog a warranty).

I was going to ask how much it cost to do the job but I didn't bother. Wasn't the right moment to ask because everyone looked very busy.
