Title: i30 2012 Revese sensors not working.
Post by: LewisBurst on December 29, 2025, 00:42:53
Car bleeps when shifting into reverse, and shows the ghost sensor image on the dashboard.
Front two sensors working correctly and pulsing/vibration when touching them.
No pulse/vibration on any of the 4 reverse sensors.

From a few videos I've seen it may be the reverse loom connection, but cant find a way to access it.

Any advice or guidance appreciated

Clean the sensors with a damp cloth  to remove any dirt as this can cause them to not work.
Then, with engine off, turn key to on and put into reverse. You will hear activation noise.
Get out and move towards each sensor and for each as you move closer to it you should hear warning sound.

When I had the rear bumper off I recall there is a joining push connection you can get at from under the rear in the void of the bumper.

If you search the site there is a post which explains the beeping and how the bleeps relate to each of the 4 sensors.
