Bonnet release cable disconnected s-class

[Col3356]

Hi, I have an s-class, s320l, 2007, and my bonnet release cable has disconnected itself ?, and the nearside (UK) WHEEL ARCH COVER HAS BEEN REMOVED AND IT LOOKS/IS IMPOSSIBLE TO GAIN ACCESS TO THE RELEASE CATCH TO OPEN IT THAT WAY. ANYONE ELSE HAD THIS PROBLEM ?????, OR HAS SUGGESTIONS FOR ME PLEASE. Colin
