2005 955 Front & Rear Parking Sensors
My front and rear parking sensors always show the first two red bars (from left to right) without any audible warning, the lights go out once I reach 10 mph and when I go below this speed they come on again.
I've also drove right up to my garage door (2-3 inches from the door) and no change in the sensor lights on the dash and no audible warning either - has anyone else experienced the same problem and if so what was the fix?

Yes. Common problem. One or more of your sensors are u/s, or unplugged, Or the wiring harness is damaged, Or unplugged. Has the bumper been off recently?
A code reader is required to find out which one, or, if you can get your ear to each sensor, sometimes you can hear them- they click. The dead one won’t.
You don’t have to buy a new sensor from Porsche. They are a VW part and fitted to many VW cars of the same era (look at the part number on the sensor itself).

I get the red lights sometimes after she sits in a hard rain for awhile. It clears up after I start moving.
Only when it rains, not snow, mud, dirt etc.
I can deal with that

When I slow down to the speed that enables the sensors, my first 2 lights are green, then the next few are yellow, then red. Either that's a difference in the light setup between the 955 and 957 or maybe the lights being red is notification that the system has a problem and why they don't work.

Red lights are an indication of a failure in the system.
I have a similar issue with mine due to water ingress in one of my rear sensors. It’s a bumper off job and not suited to the end of the winter here in Finland so right now I have to live with it.

yeah; same experience. Durametric indicated which unit had failed, and sensors can be found second hand, VW, or Aliexpress. Depending on the model, it may be bumper cover off. Knowing someone that owns an actually new Macan (rocketship) apparently they also have problems with snow, rain, or otherwise large particulate setting off sensors, I know that's why the override button is part of the car washing experience.

Wanted to see if you had any updates. I have the 2 red light issue when the car is under 10mph. I just replaced my control module and the sensor light starts off green for about 1 second and then I see the 2 red lights again. Before I changed the module I would just see red right away - is this a sign that I had a broken module and now its pinging to broken sensors?

Has anybody here ever done some research on the possibility of retrofitting parktronic to a non-sensor Cayenne?
I guess it would be much easier to buy whole new bumpers with already factory-installed sensors than to drill holes in the current bumpers.

1) Parking sensor module.
2) Front & rear bumpers with parking sensors (or drill your current ones and fit the sensors).
3) Distance displays on the front dash and in the rear headliner.
4) Wiring harnesses for the sensors, or build your own.
The module resides in the back left corner of the vehicle (behind the removable cover in the left wall of the cargo area), and needs power, ground, and CAN tx/rx. It ties into the "Comfort" CANbus as shown in the attached document. I don't know if it needs to be VIN-coded to the car using a PIWIS.
After everthing is installed and powered up, do a "handover" using a PIWIS so the CAN gateway can auto-discover the park sensor module.
This is my best, somewhat educated guess on how to retrofit the system, however it by no means guarantees a working end product...
