A guy at work asked me to fit a set of reverse sensors to his MK5 Astra.
Wasnt too bad to do.
Had them colour coded last week so they were the right colour (Halfords while you wait mix up in a spray can) then got on and fitted them today.
Bumper came off quite easy and the positions for the sensors were already marked on the back of bumper.
Work really well and his wife is over the moon (And his bumper is now safe lol)
