Six months ago I bought my old company car from the leasing firm - a Volkswagen Passat. The car is four years old and was sold with a two year extended warranty. Last week I took it for a service, but the dealer noted that the heater was not working. I've been told this will cost £250 to fix.

I’ve contacted the warranty company and they have refused to pay for the repairs, saying the heat resister that has failed. I am somewhat confused as the warranty document says it covers heater fan motor and failure of relays and switches. Is the warranty firm trying to dodge its responsibilities?
