My tiguan just finished a services last Wed, an tyres alignment has been done.
Today, when I was driving, the Tyre pressure monitor light suddently flash.
then I went to the petro station to inflatten the tyres, and found out the left front tyre pressure was 40, the rest three tyres were 42.
even after I have inflatten the tyres, the signal was still on. today's temperture is 19c,not very cool.
does anyone know what happen? how can i fix this? thanks a lot
