Hi Folks

 

I have recently started experiencing a fault on my Skoda Superb MKIII from 2018. The rear traffic alert and blind spot monitor turn off as soon as the parking mode is engaged. I am able to enable them again but as soon as the parking mode is engaged, an error pings up which states "Rear Traffic Alert / Blind Spot Monitor currently unavail." Whether the parking mode is engaged by pressing the button or when it is engaged automatically in the reverse gear or drive mode with speed less than 10mph - the issue comes up. This has started happening after the original battery died and a new battery has been fitted. I have been told by the garage that the voltage of the battery is okay and the alternator is charging the battery okay. I am at a loss here at how to resolve this issue. Any help would be massively appreciated.

 

Best regards

Any fault codes stored in parking or rear sensors (even if related to a flat battery) and if they haven’t been cleared will cause the rear cross traffic to disable itself.

 

clear the codes and try again, if it proceeds there will be a fault code now to show what is faulting and causing it.

The rear cross traffic alert and lane change assist uses the same BSM radar sensors hidden inside the rear bumper.

 

These r completely different sensors to the Parking PDC sensors.

 

Likely an issue with the master sensor module (J769).

 

 

Actual sensor.....

Is there any part of your car you haven't pulled apart JR?

I have cleared the fault codes and repeated the scan which did not bring up any faults. I have driven the car and all seems to be working fine at the moment. I will rescan tomorrow to see if any removed faults have reappeared and report back here.

No faults have come back so far, either on the dash or on rescan. The BSM is working as it should. Emergency braking is working fine during maneuvers. Seems all good for now. Thanks peeps
