Parking sensors not working

[Nateevans99]

Hi all, 

 

My partner recently purchased a 2011 skoda Superb Greenline. However the parking sensors are not working, he haslistened to all of them and they're all clicking but when we put the car into reverse there's a long audible beep (obviously signalling a fault somwhere). Does anyone have any idea what this could be? 

 

Also, the rear right door central looking and window doesn't work and we think we've located the problem to the control unit. Could this be related at all? 

 

Any help would be appreciated 

 

 

Thanks :)

Could be the reversing buzzer. Best plan is to get it scanned with VCDS or similar.

 

As for the door, have you checked the wiring loom between the door and car body? Check the front right door too

 

[Nateevans99]

My partner checked the wiring loom in the door and there doesn't seem to be an issue there. He hadn't checked the front one so will mention that to him. 

 

The speaker works in the door, it's just the rest of it that doesn't which seems odd

The front door is the common problem it has the master door controller that powers all the other doors .

Dont get caught out like a lot of people and buy rear door controller 😎

If it is any controller problem, it should show up on a scan.

Hello, partner here

 

Thanks for all your help so far.   I was a dummy and left my OBDII reader in my old car when I sold it, so haven't done a scan yet.   Will it need a proper VCDS or dealer level scan? Or should a normal code reader or Carista find it? :). 

 

Is there any way I can test the module as I've left the rear door card off for the moment for quick access till this is resolved. 

 

Thanks!

My 2012 Skoda Superb Rear Parking Sensors have been working on and off the last couple of weeks and now they have stopped altogether - just a continuous noise when I engage reverse gear so not sure if  a scan by a VCDS would show the cause or not

Skoda has been to the garage today and had a full body scan, it's the module in the back door that stopped the lock, window and lights from working. 

 

With regards to the parking sensor, it was actually a speaker for the parking sensors that had gone.

Thank You - I will arrange to have a full body scan

If it helps, since getting the car back from the garage they identified the following faults: 

Parking Sensor - B10F514 - Front park assist speaker open circuit
Door - 01334 - Right Rear Door Control Module (unrelated to the parking sensors)

 

I've ordered and received a new parking sensor front speaker, hoping to fit in the next day or so... I take it I need to remove the instrument cluster which sounds like fun.

 

I paid my local garage to read these codes, but I also bought a Carista module for ~£15 on Amazon, and that read all the codes just the same, in addition to giving info on pretty much every part of the car, and allowing me to do some funky customisations (Hill Hold now enabled :D), can highly recommend for the price.   Not VCDS and there's a subscription after the first 7 days... but definately cheaper than most garages.

 

Edit: found myself a rear right door controller for ~£27 on fleabay, hoping that will arrive for fitting in the next day or so too  be lovely to have a car that works properly.

 

Next job... reversing camera methinks...

Update: Parking sensors now work! :D.   Removing the instrument cluster in the dark in a public car park was not fun... and I drained the battery with the interior light and had to bump start, but all worth it!

 

I must say that speaker (unless I was a blind twit, it was dark after all) is mounted in a horrible place!  Facing backwards, the only way I can imagine you removing those screws is taking the whole dash out?!    I opted for unplugging the connector, popping it into the new speaker and cable tying the speaker to a loom behind the driver side air vent... Still works 😂

 

Next stop, door locks!

Hi. Did you solve the problem.
I have the same issues. Long beep is coming. I changed one sensors that was not good but still the same problem. I got it scan with obd. And its still says rear sensor. 
 

can it be the rear speaker that is damaged? And how to find that out?

You should post up what you current scan error is saying for your car.

Best is a continuity check on wiring to see if the cable has a break or not.

Hi. How can i do it by myself?

You either need to have the ability to read and understand wiring diagrams, and be able to follow wires from connector in the car to the sensors.

 

You need a way of testing if the wire has a break in it, most digital multimeters have this function (usually a beep if wire is intact) so you need to connect one end to connection inside car, to the wire at the sensor to see if it's broken or not.

 

 

If you don't know how to do all this now, then maybe watch some YouTube videos or take car to auto electrician for them to perform tests.

Hi. I went to the mechanic yesterday and after 4-5 hour he called me and says he can’t fixed it. All wiring are ok. Maybe modul or something els. Its damage. I have to go to skoda for get it checked.

If you don't have a multi meter get a second opinion regarding the wiring as it does suggest that is where the problem lies. The wires within parking sensor harness are known to go brittle, particularly where they are under stress and cause this problem.

 

You can get a tested, used parking sensor harness from Ebay for around £30 and fit it yourself. Plenty of You Tube videos on how to remove the rear bumper, to gain access to the parking sensors and wiring and the rear offside interior side trim to gain access to the module where the harness terminates. If you are going to do this, get some 3M double sided sticky pads to reaffix your parking sensor holders to the underside of the rear bumper.

As I mentioned back in October, with a multimeter you could have done some wiring checks.

 

Here is a guide I wrote for my own wiring loom issue.

I couldn't be bothered / don't have time to root out the problem with my reversing sensors so I ordered a new full system scanner and it told me that the centre right sensor was faulty. I ordered one, it was wrong but now hopefully have the correct one. They're easy to get to on a Yeti and once I've fitted it, I'll update as to how accurate the scanner is. My local VW Audi specialist wanted the car for half a day and £36 for the system scan. The scanner I got was £105 , lifetime updates and I'm sure I'll use it enough to more than pay for itself many times over 🤞🏻

[Tabarak]

Can it be the modul. I can maybe buy the modul and c if its works.
I remember my sensor stoped working after i tried to park automatically, ones i push the button its stopped working since. 
i found one modul at ebay. And I searched on the web for were the location is for the modul. Its at the right side as showing in the picture. I didn’t open it yet. I will do that after i getting the modul.

Hi, here is an update from the parking sensor issue I've been expeiencing. When the fault first occured 3 weeks ago, I got a long beep when selecting reverse and a message on the infotainment saying that park pilot was unavailable. I did the usual things of rebooting the infotainment, removing the fuse for the infotainment, disconnecting the battery for 10 mins, spraying the sensors with WD40 etc etc. As none of these things worked, I spoke to a local VW/Audi specialist and although he is cheaper than a main stealer, I couldn't justify the cost of a garage. As previously mentioned, I took the plunge and got the full system scanner and found the fault. It is also very important to note that the correct sensor is purchased as I found out (which delayed the time taken to solve the issue). I fitted the sensor this morning and it didn't fix the problem and gave another fault code. I scratched my head for a couple of minutes and decided to unplug the sensor and turn it around 180 degrees and that sorted the the issue. As you have probably gathered by now, some sensors, if not all, can be connected the wrong way round! I have attached 2 photos, one of the original fault code and one of the second fault code when the plug was fitted incorrectly. The system is now back up and running at a financial cost of £105 for the scanner and £12 for a sensor. The mechanic said I could easily be looking at £200 (depending on the fault) which is why I bought the scanner and I now have that for any future issues which I have no doubt that there will be more. The scanner will also register new batteries (if needed), carry out a forced DPF regen and so much more. I hope this helps 🤞

[DEL80Y]

For anybody else thinking of getting a scanner I can highly recommend Autel AP200

Its only £58.64 on Amazon the now

Do any of you know the location of the buzzer for the parking sensors in an estate?
