How much larger tyres? if they exceed 5% in diameter the system can be mixed up cos it expects a certain VSS(vehicle speed signal) at a certain rpm/gear/torque read on the CAN bus cos it was "calibrated'' from factory for that...as the VSS is altered by the tyre's size it doesnt match the expected values and the system goes to default... i've seen this few times and refitting standard tyres fixed it but i've also seen cases when the tyre size wasn't an issue so you should fit standard dimension tyres for test and if the symptom goes away at least you know it's that, strangely the sensitivity of these systems is not the same on all ... though the best would be to read the stored fault code before that cos it might be something coincidental so at least you know what's about
if you didnt read the owner's manual dowloload this https://www.keepandshare.com/doc3/58...es-pdf-2-3-meg
cos it's time to do it to see how important are the tyre dimensions and pressures, if you dont have patience reat at least the last page
