Hi everyone,

I’m hoping someone here has come across this exact issue, because after 7 months and multiple visits, neither my dealer nor Škoda’s technical support has been able to identify the cause.

Car: Škoda Superb Sportline, 2021, 200kW

Problem:

When braking, the side sensors intermittently trigger a warning that there is an obstacle very close to the car — even though there is nothing there. It happens sporadically (not every time I brake)

What has already been done (all without success):

• Control unit replaced

• Multiple calibrations of the sensors

• Sensors themselves replaced

• Wiring in the front bumper replaced

• Wiring to the control unit replaced

• Software/firmware updates applied

• Sensor mounting points inspected

• Sensors recalibrated again

Despite all of the above, the fault keeps recurring. Nobody at the dealer or at Škoda technical support has been able to explain the root cause.

When did you change the battery last? Electronical gremlins, which are both varied and inconsistent amongst owners are first put down to the battery on its way out.

I think after that you can get wheel speed sensors which fail and start to do the same.

I'm assuming the dealer has run fault code scans (Have they? Did they mention the battery or wheel speed sensors?) but it looks like they've very much focussed on the sensors and associate framework being the issue and not whether something unrelated causing a ghost issue.

The car is 5 years old and the original main battery has never been replaced. Nobody has tested it or even considered it as a possible cause so far.

One thing worth mentioning: this issue happens roughly 60–70% more often when it’s raining compared to dry conditions. Could that be related to the battery?
