took my car in for warranty issues

[leasaunce]

Hi guys,

I took my car back to the dealership yesterday to go it fixed. for: Dash rattles, Rear spoiler

I got the car back yesterday, before I hand in my car I checked on the Fuel remaining, says 50km. then when i got it, 10km (also the average fuel consumption in MODE 2 says 10+L/100km). They must've driven my car like crazy! Before I gave the car to the dealer, average fuel consumption was 8.5L now 10? (im guessing they reset the Average fuel consumption, BUT WHY!?!?!)WTF?!

They played the headunit system as well
(they said they took the car into the VW panel beater, no idea where that is! but I thought they would put the car in the back of the truck and take it to the panel)
anyway...what do you guys all think? I'm going to give them a call, to resolve this issue.
