Fuel Sensor

[4868rh]

Hi, Have just received my SV6 back from holden and have been told a Fuel sensor was faulty.
I took the car to holden after the transmission warning came up in my dash. the sensor has been replaced and all seems fine.

My vehicle is covered by the holden extended warranty which is the holden 5 Year/100,000klm warranty. My vehicle has only done 25,800 klm and holden have told me this part is not covered by warranty and that it will be $358.00 to fix, My understanding of the warranty is that this part and labour should be covered by the warranty.

Any help would be appreciated.
