i put this topic up on the superb mk2 owners forum but unfortunately didn't get any replies so thought i would try you guys, 

i am having a problem with the stereo in my (2013 superb 4x4)when using (DAB radio) it is constantly going in and out of signal every phew seconds making it imposable to listen to dose anyone have any idea's on what could be the problem and how to fix it?

cheers kev

I don't know but it may have an aerial booster/amplifier, perhaps in with the aerial perhaps not.  You could ask at the Dealership parts department and if so for it's location to inspect it.

 

I don't know if the infotainment gives signal strength to stations, I forget, but if it does you could monitor that, would a correct level VW scan tool cover this, sorry again I  don't know just thoughts.

   

Think you might find the dab aerial wire in the rear glass. People in the past have broken the connection by vigorous cleaning.

 

The other one you could check is whether you got it set to auto select region or something. This is where you are happy for it to switch between similar stations. If you have it toggled as no then you can end up on one that you loose and fades in and out.

 

Commercial stations don't always have the best coverage as the BBC so if an LBC News hound say you may find it drops away as you go down a dip since there are no fill in stations. Happens in rural parts whilst the BBC stations are rock solid.

ok thanks for the reply's guys much appreciated!
