Just bought a 12 plate Superb and the rear park sensors appear not to work. No beep when reverse is selected. The fuse also controls the swivel lights  etc which are working fine.

any clues appreciated

 

TIA

Is the display coming up on the radio/nav unit?

Nothing on the display, either on the nav on dash.

Do the reverse lights work?

Yes reverse lights are working fine 🤫

Does the car have both front and rear sensors, or rear only? If it has both, are both ends not working or just the rear?

 

You've already ruled out the fuse, and there are no relays controlling the system. It's using the drivetrain CANBUS network, so I doubt the issue is there since a CANBUS failure would be throwing up errors in other areas of the car as well.

 

One last easy thing to check is whether the button on the centre console activates the system.

 

If you have access to VCDS or similar, a fault scan would be a good next step. If the system has detected any faults they'll show up there and can help with narrowing down the problem. After that it might require a look at the control unit to see if there are any issues with wiring to it, or damage to the unit itself. Annoyingly, it's buried behind the side panel in the boot which is an absolute pain in the arse to get to. Before that, get under the rear bumper and check the connectors to each of the sensors, and where they route into the car in case there's any damage done down there.

Thanks for the reply Chimeara.

there is not a park sensor switch on the centre console.

The car has had a Skoda towbar fitted so not sure if the park sensors have been disabled.

I don’t have VCDS unfortunately 

i guess the saga continues 😕

If there is no park sensor switch on the center console, than the park sensors are after market (or not present at all ...). In any case we will not be able to help you, since we do not have a clue about what specific system has been installed.

andrehj. Thanks for your constructive feedback.

For your information, the car has factory fitted rear sensors so they do exist.

I was looking for potential assistance, not a sweeping ‘we can’t help you’ comment.

I am hoping you don’t speak for the entire Briskoda network

I wonder if some lazy person disabled the sensors rather than figure out how to configure the car to shut them off when a trailer is hooked up.

 

If you go to the diagnostics section here, there's a thread with a list of members with VCDS or similar tools who are willing to help other members. I'd suggest finding someone there who can scan your car so we can figure out what's going on.

Thanks Chimeara I’ll do that now👍👍
