A year ago I replaced a front wheel speed rotation sensor since I had these warning lights. All ok. Last week I had all the lights some on again and the only thing I did was slightly inflate one tire.
I left the car for a week n the garage and when I started no warning lights!
The car had not been moved and had been parked with the warning lights showing.
My ****-eyed theory was that it had got used to one tire being a bit down so that as soon as this changed it thought there was an error. However, the car was not moved or moving when the lights disappeared.
Any ideas why?
