What do you by the JB4 'not working', if you connected the device wrongly than you might well have triggered error codes which aren't visible....equally did you damage any connectors/chips when fitting the JB4?

Not sure where you stand with the warranty given the fact you have actually 'chipped' the car (or be it unsuccessfully)?
