Group,

The Parktronic now does not work as one of the sensors is bad.
I put the VAG Com on it and all raw readings look OK.
Is there a way to see if it's the module or the wiring before I starting tearing things apart?

Thanks,

Ray

 

Common problem. It is probably what Audi calls the horn and we think of as the speaker. I had the same problem a couple of years back and had the dealer replace it.

 

I believe the VAGCOM allows you to sound the parktronic horn. Give that a try to see if the horn is bad.
