I think i have a fault on my Tyre pressor sensor, mainly because i have only done 5000 miles from new and the tyre pressures are fine, tread is fine, i havent kerbed or hit anything hard on the ground so i dont know why this light keeps coming on, i have reset it a few times but it comes back on like a week later. i want to take it to a dealer to look at but i want one i can trust who wont say its my fault and try and charge me, also do dealers charge you just to look a your car?
