Hi everyone hope you are all well I have a problem with my parking assist on my vauxhall mokka as soon as I turn on the ignition it chimes and I get a warning light and a code of 136 I have been to vauxhall who tell me I need to clean the bumper Any ideas? As it is getting very frustrating! Would anyone know where I can locate the module I would much rather just dis-connect it Thanks.

Hi Derek....welcome to the Forum

I would check that the sensors are clean and they are easy to check to see if they are working.

Place the gear in reverse, switch the ignition on so the warning lights illuminate on the instrument panel BUT NOT WITH THE ENGINE RUNNING  then listen carefully to each sensor and you should hear a light clicking noise if they are working correctly. Generally, if there is no clicking noise then it is likely to be a faulty sensor.
