Renault steps up

Called the garage today about the window.  "Might be the motor, might be the wiring.  If it's not in the motor it's not in the warranty, then you'll have to pay a diagnostic fee, thats £70".

So I phoned Renault.  They were incredibly helpful (thanks, Nicki, the Customer Support Manager).  Renault are aware of this fault, and will cover the regulator and motor and the wiring loom for 4 years.  Our car is 3 years and 360 days old.  Really!  So book it in now.  (and if that's not the problem, will have to pay the garage's diagnostic fee...!)

Booked in.
