Bonnet cables

Anyone that runs R55 R56 etc needs to make sure that their bonnet release cables are still in place where the single cable joins the double cable in the oblong black box ,
pulled the bonnet release last weekend to check fluid levels and the release just pulled with no resistance.
Did a few checks and the cable not detached at release lever ,which meant detached where the single joins the double cable , what a job to release bonnet catches from under the car ,made sure everything was running free rebuilt and all is well ...nightmare of a job .found a few YouTube videos and one in particular was very good
