PDC/Park Distance Control, permanent warning when reversing

emax · Jul 13, 2024

I had my car at the agent for some issues to solve, one of which was the PDC sensor rear right. It produced a permanent alarm when reversing. When I got my car back after 10 days (there were more things to do), they told me the PDC problem was solved.

It isn't. When reversing the same shit happens again: alarm without any obstacle around the vehicle.

Since I don't believe they are just morons, there must be a different reason. Perhaps the rear right PDC sensor is not broken and has never been - but it's actually a cable or a plug problem? A pinched cable or a wiggling plug, I don't know.

Next time I am there I will suggest not to replace the sensor but to swap the rear right sensor with the left one. If the problem then persists on the right side but no problem on the left side, it MUST be a problem in the wiring harness.

What do you think?

Anybody else having a similar problem with the PDC?

I have the same problem with the outer rear passenger side sensor. Particularly in wet weather or first thing in the morning. Once things dry out it’s OK. So I suspect a loose/bad connection or faulty sensor.

I will be contacting Magics in the next week or so once I get my camper trailer back from its service, it’s waiting on some warranty parts.

Stay tuned.

Hello emax, have you checked if the alarm matches the proximity indication on the screen image, it could also be a software problem. Something similar happened to me randomly and with an update it was corrected.

. . . same here (over a year up to the first inspection) the right rear sensor of the PDC was faulty. Nearly always on in reverse (95 % of time), only in rainy wheather sometimes the sensor was alright.

After the Inspektion the PDC was okay for half an hour, I reversed to the workshop and suggested to exchange as wished the sensor or check the connections another time.

They changed the sensor (so I was told), up to now the PDC works for 6 days. Fingers crossed.

It is not at all related to proximity, as it fires always when in reverse gear, even if there is no obstacle at all.

Place it in the middle of an empty Aldi parking area or of a football ground, it starts soon as you switch to reverse rear.

PS: The proximity image on the display always shows the closest possible distance.

. . . I also had the same damage pattern. Sensor always red with display of the smallest distance, even if there was no obstacle to be seen far and wide.

After the workshop's first attempt, the distance was indicated correctly (e.g. green bar, then yellow), but the right rear sensor always also showed the red bar for the smallest distance, i.e. two bars in the display in this field.

After replacing the sensor, everything is now working as desired - for the time being

just the sort of places where a child unexpectedly runs behind you

I just assume the sound is a reminder to be cautious.
I have it turned the volume down and it doesn't bother me. Even though perhaps it should, my equanimous nature kicks in.

Like any repeated false positive this hast just the opposite effect: I dont't take it for serious any more like I would would do with a reliable signal. A real warning ist very different from some nanny noise.

It rather sounds like a strange idea to me that a cacophony of unreasoned signals could improve someone's awareness.

But interestingly you seem to have found a way to adjust the volume? Can you tell us more?

When I fly home later today, if we are able to dodge gale force winds and rain in the dark, I'll try to find the intell.

Some things seem to be too simple to find them.

Thank you!

I had one of my intermittent rear sensors replaced today. There isn’t any pattern to it. Sometime it would keep going off (nothing behind me) and sometimes not. But more so in the wet or after a wash.

It was described to me that the connector or the back was showing small signs of corrosion.

All good now. Hopefully this has finally fixed it.

Mine is still nagging.

Before just replacing something they should swap the left and right sensor to check for sensor vs. wiring issue.

Same; rear driverside sensor is always on when in reverse, even with no obstacles close by. Requested sensor replacement at next service.

My front PDC started having issues after 9+Month of ownership. It will now start beeping off when there nothing in front of me. Infotainment will show red at closest distance. PDC Sensor cleaned. As soon as i start driving it stops. If i stop after about a few second it will start beeping. Faulty sensor?

emax · Sep 10, 2024

The workshop has now fixed the problem - on the second attempt.

No more unnecessary noise when reversing. What a relief.

Did the replace the sensor? Thanks!

This keeps happening to me. What is the fix please.

I would tell you - if I could. But when I asked, Krah+Enders only answered that they "... do not provide any information about warranty work".

The simple paradigm is obviously "What a customer does not know, he cannot sue for."

For me, this deserves only one possible comment:
