Help!.. which one is Parking Sensor number 2?

[MarkieD]

Hi guys, I’m a newbie who’s got a fault with my parking sensors. (Continuous red line)
Having checked with the OBD it says that parking sensor number 2 is faulty…
Does anyone know which one that is?…I have no clue where they start numbering from and there’s 6 on each bumper!

I don't know........but get someone to put the car into reverse and hold it still on the brake....then wave your hand right by the sensors one at a time....the good ones will faintly click....the bad one wont.

Its the one on the drivers side at the front. The outer one is number 1 and the number 2 is the next one in - tight at the corner
