Assyst plus is very clever. Trouble is on almost every car thats come in to me for the first time the price ive quoted over the phone has been totally different from what the customer has had to pay. I always try to explain on the phone that so many factors need to be right in order to quote correctly. The service light and individual items must have been reset correctly in the past. The individual maintenance procedures must have been adhered to, otherwise assyst plus would have calculated incorrectly. So to owners of all cars with assyst plus: read your service book, work out what needs doing and make sure the cluster is reset properly. When done in this way you cant go wrong in the future!!!!!
