Measure
Before carrying out any repairs consider the following external conditions which can affect PDC operation
External conditions
1. High plants, flowers, vegetation and kerbs can lead to incorrect warnings near the vehicle.
2. Gravel paths, cobblestone paths, pot holes, grates, sharp bends in the road,
slopes, driveways / ramps can lead to incorrect warnings.
3. Different weather conditions / environment influences can restrict the function:
- Water on the parking sensors (widening of emission area)
- Ice, snow on the parking sensor or in the transition area to the bumper
- Exhaust gases of the vehicle, steam (heat swirls for example when accelerating change
the physical properties of the air and thus the ultrasound of the parking assistance)
- Interfering sounds (pneumatic brakes of lorries, animal alarm, other active ultrasound source in the surrounding area, such as parking
assistance of other vehicles)
4. Local environment
- Fluorescent lights
- Induction loops on traffic lights and car park barriers
- Ramps / driveways
Vehicle
5. Check the installation of the number plate holder for:
- Protruding number plate / number plate holder
- If possible do not use any advertising carriers
- The number plate size must match precisely the size of the basic carrier
- Fit the number plates only on original basic carriers

- The number plates and number plate holders must fit on flat/flush to the vehicle
- Check the number plate attachment on the corners (bent-open corners)
6. Add-on parts / modifications / service installations which are not genuine Bentley accessories can lead to incorrect warnings
7. Previous damage which is now painted over (see vehicles repair history)
Parking sensor damage
8. External check of parking sensors for:
- Dirt, ice, foreign bodies, foil stuck on
- Check any damage on the bumper, air inlet grille and underbody which may indicate a parking accident
- Mechanical damage (stone chips, scratches)
IMPORTANT: With the following examples stone chips led to the failure of the sensor:

Paint overspray
9. when painting sensors ensure to paint within area specifications, removable layers of paint on the membrane can lead to false signals

False Detection
10. Where false detection is observed, the operative should conduct the onward procedure:
•

Record a video whilst sitting in the driver’s seat showing the false detection on the MMI

•

Whilst still recording - Exit the vehicle to the location of the suspected faulty sensor

•

Obtain a close up angle of the sensor TIP: If the video is not high resolution, please take a wide angle image to show location of the sensor

Then
•

Obtain a close up video to highlight any damage

HINT: Save the video as this may be required when opening or responding on a previously opened DISS query

Warranty accounting instructions
Stone chips and scratches are not complaints in the sense of warranty. Therefore dirty sensors should be cleaned and not
replaced
Any sensors which are replaced for stone chips, scratches or any other type of damage will not be approved for warranty
