Following the fitment of two new front tyres on Monday, within an hour of collecting the car my wife had a 'TPWS Malfunction. Contact Your Dealer' warning flash up on screen. It's now not allowing the pressures to be shown so initially wasn't sure if a tyre was losing pressure, but all looks good.
Is it possible that a sensor has been knocked or damaged during the tyres being swapped over that has made the system throw a wobbly? I have the car booked back in on Friday for the tyre place to have a look. I rang Lexus and they want £115 to put the car through a diagnosis.
I was just wondering if it's possible to attempt a reset that may cancel out any fault?
