u mean the service interval LEDs right.well the input comes from the DME ie the computer,which calculates,among other things,the fuel used,distance travelled,accelerator input etc etc.no one particular sensor controls the LEDs.
maybe you have not been thrashing the car much...? he he JK.
i 'd suggest you do an oil service reset and see 1000kms after if at least 1 LED extinguishes....
if it doesn't...who cares anyways....do manual monitoring like most cars....by having that little sticker pasted on top of the windshield to tell when the next oil change is due.....
