Parking sensor issue

Featured Replies

I have have my Superb 2.0TDI L&K from new from last July. The car has been plagued with electrical issues, car not starting, headlights not self levelling, electric handbrake not releasing, infotainment issues etc, since I got it, the local dealer eventually replaced the battery about a month ago and I've had no issues since, no surprises really. Just before the battery change, I reversed in to steel bollard, the parking sensors never indicated an obstacle and the reverse braking didn't actuate either, even though the dent is only about 30mm from a sensor! Both Skoda and the local dealer have said the sensors are only aids and should not be relied upon, I couldn't see the bollard as it was below the height of the tailgate. My fear is that if it was a child that I knocked over and Skoda come back with the same answer, what is the point of even having these options?

I've had Octavia's and Superbs since 2003 and this is leaving a very bitter taste in my mouth, it's not the cost implication, it's the denial from the manufacturer which I find hard to believe. 

Has anyone had a similar event?

 

Thanks, Mark.

Low battery stops all manner of things working, on my fabia it stops the rear sensors, though it gives a different bleep when engaging reverse and a slightly different screen to indicate its not working, however most people wouldn't realise what that meant, neither did I until I thought, crickey that looks close.

 

The superb has a strange complex micro hybrid charging scheme, which I'm still trying to suss. One thing I have noticed is that when the battery is low (as my car was when bought it), if you drive with no ancillaries switched on, headlights or heated seats for instance, the charging scheme doesn't seem to make much of an effort to recharge, if at all. (As a retired electronics engineer, I've done lots of monitoring of voltage and charge current status with my test gear)

 

I have the slight suspicion that the battery management software is not perfect. There have been software updates regarding this on the past.

 

In your case its possible the car was stood, or interior lights left on in a showroom for instance and handed over in a deeply discharged state. Subsequently, the problems you had.

I wonder if all the WLTP car-parked cars will need new batteries after a few months left out in the cold.....

Thanks Xman, I'm an electronic engineer myself, so I completely agree with you. If the 5v is sometimes dropping, then the digital electrics will become intermittent. It's Skoda's horrific attitude, denying all responsibility what really concerns me. All my other cars have been bullet proof, absolutely went wrong with them and this one is a dog!

Denial of what issue?

 

It is not an automated vehicle and as drivers we are responsible for its control.  Skoda's position would be repeated by all manufacturers.  

 

So what about the view from the front and down the sides, can you see those areas fully? What did you do on your previous cars?

 

I am interested in the warning you got @xman, as that's the point where we either get out of the vehicle or get someone else to watch us back up.

 

 

Highly debatable considering whats implied in their marketing.

There was a longer bleep than normal from rear passanger side speaker, different pitch maybe. And screen (dance radio) went blank I think.

Check out this detailed overview of all the safety features you can find in a ŠKODA, encompassing advanced driver assists, the protection of children on board, and a rundown of the safety equipment in each of our models. (my bold)

 

And advises:

Safety Assistance Systems and Driver Assistance Systems

So no positive advice that parking sensors are inoperative?  That should be there as the most problematic system failure is credible erroneous indications, ie everything appears ok, as it does all the time!  System degradation should be advised, it is for front assist and other systems were I have had transient error messages.

There is a disclaimer in the operator's manual.

 

WARNING

■ The general information relating to the use of assistance systems must be observed  » page 212,  in section Introduction.

 

■ Moving persons or objects may not be recognized by the system sensors.

 

■ Under certain circumstances, surfaces of certain objects and types of clothing cannot reflect the system signals. There is a danger that such objects or people may not be recognised by the system sensors.

 

■ External noise sources may affect the signals of the system sensors. There is a danger that obstacles may not be detected by the system sensors.

 

■ Before reversing, make sure that there are is not any small obstacle, such as a rock, thin post etc., in front of or behind your vehicle. Such obstacles may not be recognised by the system sensors. 

Well that covers the legal aspects then.
