my parking sensors have been working fine till last week. Normally when working they should do a high pitched short beep when put in reverse to start and then beep according to how close i get. However in the last week when i put the car in reverse now all i get is lower pitched longer beed, and it continues intermittent every 2-3 secs, and dose not change however close i get to things.
It only works properly now 2/10 when i put in reverse.
Any ideas? thanx
