Just curious. To try and cure my ongoing problems with Skoda's remote app not working with my car, Skoda UK have requested I visit a service centre and ask them to perform a "Clamp 30" procedure.  

 

Does anyone know what that entails?

 

Trying to ascertain if it's a quick thing, whether to book an appointment where I wait with the car or not. 

 

Thanks 

This may or may not be of any help but a quick Google brings this up from another forum, and while it refers to a previous generation unit it seems to refer to some sort of system reset/update? https://www.vwwatercooled.com.au/forums/f78/rns-510-skoda-columbus-cd-dvd-slot-locked-clamped-due-invalid-clamp-state-127194.html

That seems to be related to the CD/DVD not releasing a disk. I don't think it's related to that. The only other google result I found was to something to do with a 30A fuse on the battery clamp... and I am nor sure that's relevant either! 

My line of thought was that it was some sort of software update for the head unit which is what I assume the Skoda app connects with, for some of the functions at least, such as sending destinations to the sat nav as well as registering the trips, fuel, plus the remote lock/unlock etc.

Clamp 30 is battery voltage, nicely explained here: KL15, KL30, KL31, KL50, KLR and Ignition Position

The technical terms to confuse people do make me laugh....

 

Clamp 30/Terminal 30 is battery voltage - Terminal 15 is ignition voltage.

 

A clamp 30 reset is a smart way of saying turn it off and turn it back on again, ie. disconnect battery for a while, reconnect and clear fault codes. 

You see reference to this in wiring diagrams. Clamp 30 is a permanent live / 12V, clamp 15 is a switched live / 12V after the ignition is switched on.
