Hi All,

I have a 2017 2.0 TDI 190PS DSG Sportline Combi.  It has KESSY

 

Quite often when I scan the car with the Carly App and adapter I get the above error message.  I clear it and after a while it comes back.

 

The thing is I only have two keys.  Both of which I've already replaced the battery in.

 

I've searched in Briskoda and Google and not much comes up.  Only thing I can find is a VW Technical Service Bulletin 57-19-02.  But it just says about things that will happen because the battery is low (none of which I have) and that vehicles with KESSY a message may displayed on the Instrument Cluster which I don't get.

 

Any idea what could be causing the error to come up?

 

I also sometimes get an error for start/stop inactivated because of low voltage.  Could it just be the car battery voltage is low and the car it throwing up B147B18 as a spurious error?  I know a low car battery can sometimes cause strange errors to happen.

 

Thanks.  

 

@MunsterScot Did you manage to get to the bottom of this? Superbs usually have 3 keys – the nice metal one and the two plastic ones. If you bought pre-owned, maybe the third key was “lost” inside the car somewhere.

Never got to the bottom of it.  I never looked in to it much to be honest.  I just reset the error code each time it shows up.

 

I did buy the car pre-owned and only got 2 plastic keys.  I did think about there being a third key in the car someplace.  I ruled it out based on the car has Kessy so if there was a key inside the car with enough battery life for the car to detect it then I should be able to open the door an start the car without having a key on me.  But I can't.

 

Maybe I was wrong to rule out the third key in the car someplace and should have a good search around to be sure.
