Hi does anyone know where i can get a split charge relay and the instructions how to fit it so I can wire in a leisure battery ?

Your local motor accessory shop will have a range of Automotive relays. The only requirement is that it is 12V and minimum current handling capacity of 30A (if you have a higher output alternator than standard then you could consider fitting a higher rating such as a 45A)- you don't have to specify one as being required for a 'split charge' system. Single pole version (or a double pole) will be fine and one with a mounting bracket will make securing it easier. Alternatively, you can purchase a 'Smart Relay' such as the SMARTCOM which are easier to wire and do not require a feed from the Alternator. Smart Relays are available in a range of current handling ratings and can be found on Ebay, Towsure, etc, or just google a search.

Wiring details for fitting and wiring a conventional relay for the split charge function and 12V operation for the fridge (if fitted)is covered in the Club WIKI.

They sell them on JustKampers:

On the other hand - VW installed split charge systems with 30 amp relays.
Mines been working fine for the last 8 years.

Yes indeed they did....I replaced mine 2 years ago after it melted permenantly connecting the leisure to the starter. This forum is littered with similar stories the most common being blowing 25amp fuses.
Yes they work, sometimes for several years but electrically speaking the standard 30amp split charge setups commonly used are just adequate. If repairs or new circuits are being fitted then why not upgrade to something that can comfortably handle any eventuality?
At least my suggestions don't go way over the top like some.....100amp relays/100amp wire etc.
