Can you update your info. pls.
It says you are only interested in a Tvan.
Plus , if you can tell us which model/year Tvan you purchased it will make it easier to help you.
Doesn't matter if you purchased it privately, or bought from a Dealer new or used.
Remember Track do have a Service Dept., and they do advise when needed.
