Hello , i have Citroen c5 with parking sensor problem After i painting one sensor , no one does not work now .
Its says the code BCA and BC0 ftont left sensor
I bought 3 sensor on the left now are new.
still same problem
These sensors are VERY sensitive and if they are dropped they can be damaged permanently. Diagbox should tell you what the issue is, do you have the proper fault codes as these are not returning anything.
