I have checked the presence of the fuses 43,44 and 45 and 8 which is listed as towing stability etc, as are the others mentioned. I'm not going to pursue this any further as the amount of work involved and having access to VCDS is prohibitive, as I can't do it myself these days. I can live with not having the battery on charge whilst driving and as long as the fridge is cold I can stuff it with ice-packs and for most journeys (that I would undertake) that would be sufficient until I can access 240v again. Thank you all esp Hugh Gabriel abd Chimaera for sharing your knowledge and experiences.

This is all very good information and hopefully will point me in the right direction.. i do have a fully populated 13 pin socket on the car although I have not accessed the cable side to see if all the wires are there.. (bit awkward for an old geezer with dodgy knees etc).. I will certainly check for the presence of fuses 4,43,44 and 45. I appreciate that this is not necessarily a definitive answer it will certainly narrow the possibilities somewhat. Of course - back in the day I would simply have run a cable (via a fuse) from the battery to a changeover relay and a cable from an ign only live to the relay actuator connection so that I have a fixed live to the socket, which is disconnected when IGN is on and diverts via the relay to the appropriate pin in the socket. But I've no doubt that would start creating havoc somewhere in the management system, and, with all that sophisticated technology already installed it would be good to make the addition complimentary. However - I am towing my caravn for the first time in anger (not a dummy run) this coming weekend and I am resigned to reliance on 240v for the fridge and battery charging. Regards towing the caravn which weighs in at just over 1000kg tare and 1200kg MAM - it tows like a dream. Steady as a rock with Alko coupling stabiliser fitted. After a mile or two it's almost as if it wasn't there it is so comfortable. Unlike some outfits I have had in years gone by. The Superb just takes it all in it's stride. great car.

This thread has answered my questions about my Superb Elegance Sept 2009 and towing my caravan. I had been thinking that I had an electrical fault with the Towbar as I do not get Leisure battery charging or fridge charging. Also The habitation relay in the caravan should DISABLE 'domestic' 12v services - interior lighting and water pumps etc when travelling and ENABLE fridge and battery only - and this does not happen. I DO get an indication on my Columbus that the trailer is attached and I do not get annoying 'beeps' with the indicators when towing. Basically all the lighting systems and ECU changes to parking sensor control operate as they should. So reading this thread my car obviously falls into the group which did not have the wiring installed from the front of the car to supply the 12v live and the 'ignition enabled' 12v. So my question now for one of the very knowledgeable contributors here is How do I get this fixed please? Thansk.
