PDC error

[spartacus68]

So after the charging solenoid lock episode, my wife tells me there's a PDC fault (park distance control). I thought this may just be the dirty roads considering we had over a foot of snow last week and temperatures of -23.

So the snow is melting and temperatures are back to normal for this time of year. I tried cleaning the sensors but the problem persists. These sensors are expensive, especially the front ones which are pre-painted. I've sourced a supplier and have used Hubauer Shop before, so I know they are genuine BMW and avoids going any where near the main dealer.

The car has front and rear sensors, auto park, plus a reversing camera. It's probably just one sensor, so how can I go about determining it? I'm used to working with VCDS on Audi and Volkswagen cars, but I know genuine BMW software is likely to be ISTA software. Any links to European sellers, I mean plug and play, so software, cable, the works.

Any other tips appreciated to solve this please, thank you.

To find out which of the sensors is broken:

- switch the system on
- put your ear right next to each sensor
(apparently you can also use a drinking straw - one end in your ear, the other end on the sensor) - never tried that though.
- the sensors that are working will emit a faint "ticking" sound
- the sensor that is broken will be silent


The sensor that is silent is not necessarily broken - so before you order a replacement take it out and see if:

- the electric contacts aren't corroded (happened to me before)
- the cabel going to the sensor is still attached (could have been ripped off by a chunk of ice/snow - I had that on my 7-series before)

Just an update. Detailed the car today which will have helped, and then used an electrical contact spray on the control module for Park Assist that lives under the back seat. So far, so good - time will tell.
