I have a Mk3 Octavia Elegance which has automatic wipers.

However the automatic wipers have recently stopped working - they just do ordinary intermittent wipe in that stalk position.

This seems to coincide with a trip to the dealer a couple of weeks ago where the battery was changed.

 

I've run a scan in VCDS, which reports this, and I'm assuming relates to the problem:

934149 - Rain/Light Recognition Sensor
          B1366 76 [008] - Wrong mounting position
          Intermittent - Confirmed - Tested Since Memory Clear
             Freeze Frame:
                    Fault Status: 00000001
                    Fault Priority: 2
                    Fault Frequency: 5
                    Reset counter: 238
                    Mileage: xxxxx km
                    Date: 2020.08.26
                    Time: 14:10:25

 

I'm not aware of anything happening which would disturb the sensor position, so I'm wondering if it could be something caused by the battery change which has upset the sensor?

 

Is there anything I can do with VCDS to try to fix it - for instance is it worth trying to clear the fault code?

(I've never really used VCDS to try to change anything before so I don't know how best to use it.)

 

Or maybe something has indeed moved the sensor - in which case is there anything I can do to try to put it back?

 

Thanks in advance.

It's marked as intermittent so clearing it should solve the problem for now.

 

You could take a look at the sensor from the outside. They have a silicon pad so it should be obvious if it's not fully pressed against the windscreen. Feel free to post a picture too if you want a second opinion...

Many Thanks for that.

 

I've cleared the fault but then tried the wipers and it came back straight away.
 

I'm struggling to get a picture good enough to post here but it *seems* to be pressed in place.
However the swift return of the fault code suggests it's going to need a dealer's attention in any case?

@DavidYCould you resolve the issue? I have the same problem with my light/rain sensor 😞

Hi Vahids,

As mentioned above I cleared the code but it came back - so I was thinking I'd need to ask the dealer to check it... but then not many weeks later the rain sensor started working again and I've not noticed it failing again.  (Also I suspected there wouldn't be much point asking the dealer to diagnose when it's working, so I didn't mention it to them when service time came around.)

So I'm sorry I'm probably not much help to you. 😞

Hi David,

 

Thanks for your answer and very kind for getting back to me anyway!
