And here is another interpretation ...
Can this suppliers tunes be classed as "faulty" therefore refundable because they directly allow( encourage) the operation of a vehicle without legislated emission controls.( ie. MAF).
Not only does it allow the vehicle to operate in an illegal manner but also prevents the operator/owner of said vehicle to correct the situation and make the vehicle comply with legislation.
Serviceability is a legislative requirement of vehicles. see the above link to the ACCC recall site and note 2008/10385 regarding the Honda Jazz.
"Defect Details: During the manufacturing process, damage may have occurred to a joint in the handbrake lever assembly mechanism. Continued use may cause sufficient wear for the joint to detach and make the handbrake assembly unserviceable."
So the defect with the Jazz is not because the handbrake lever can wear but because it would become "unserviceable" after that wear.
I suppose because after a time a fleet of Jazz vehicles would be running around with unserviceable hand brakes.
A legal
precedent set regarding serviceability maybe?.
