poo appens, I did a similar thing to mine 3 years ago whereby the reversing sensors were pinging away as I was reversing near to a telegraph pole, to then discover that they were actually warning me about a dwarf bollard that I did reverse into . Whilst the Bumper is spilt and cracked, the local MoT man just makes a comment under 'advisory', and I've lived with it ever since. To be honest it actually acts as an 'aid' when parking in car parks and inner-city, especially France, where others give it a bit of a wide berth . For me, the car is in effect worthless, it survives from MoT to MoT, and I wouldn't expend much cash on it for a cosmetic repair/exchange.
