I bought my car knowing that these errors came up as it had a new bumper/lights installed to the car after it suffered a bump (i made sure they worked fine first). It seems that the car doesnt recognise the lights properly even though they work perfectly fine. Is this something that requires to be taken to a garage or can it be fixed myself? do they need to be programmed to the car in a certain way for the error messages to be removed? Again the lights work without any problems at all and as they should do.
