I bought a used Skoda Fabia that is fitted with a parking assistant (reverse parking sensors) which does not seem to work.

According to the manual when I change into reverse it should either make a short beep (for everything alright) or a long beep (for "parking assistant not working"). Instead it makes no sound at all and the sensors also don't make a sound when there is an obstacle.

I checked the fuse (5er fuse in slot 9), but it looks ok from what I can tell.

Is there something else I can do myself before hitting up a repair shop? This is my first car and I have no knowledge about car mechanics, but am not afraid to learn and get my hands dirty.

The car was checked shortly before I bought it but they found no problem. According to the family member I bought it from the parking assistant worked before that.

UPDATE: As suggested, I checked if my rear driving lights work when I am in reverse. At least one side (back right) lights up, not sure if it should be two lights or if that's just normal?

UPDATE2: I finally checked some weeks ago. Doesn't seems to be the fuse. The multimeter showed power on both sides and the AC is wired on the same fuse and works.

I had very similar symptoms on a BMW, the sensor itself was faulty and the problem was solved by replacing it.

There are two ways of diagnosing this that I can think of:

  1. Look at the sensor readings in the live data section of a diagnostics tool
  2. If you don't have access to such a tool, buy one new sensor and fit it to each position one by one until the problem is resolved
