Seeking help from the car enthusiasts

My 2015 Vauxhall Insignia has a yellow warning light on, at the revomener, with an exclamation mark inside brackets.

What's wrong with her?

  • If it is the TPMS, you need to correct the tyre pressure and then go into the dash display and reset the fault, some cars have sensors on the tyre valves that actually read the pressure and some work out a low pressure from the ABS system, a tyre with a lower pressure turns at a different speed and then flags up a low pressure.

    I normally use a YouTube video to reset as it’s a function the owner normally does, and every car is different. My code reader will only recognise a fault, only top end readers have this function. If your car has sensors attached to the tyre valve then normally if the code won’t clear then a tyre sensor has failed, they have watch batteries in them that eventually go flat, unfortunately they are a sealed unit and a new one will need cloning (learning) to the ecu.
