Hi Guys im new to the forum and is having the same issue. the car starts perfect in the morning and if i check it throughout the day it works until 4pm. the car refuses to accept the key. So i leave the car at work and the next morning it starts up perfectly. I have replaced the starter and the alternator as well as sending the car to mercedes and getting the lockset changed and 2 brand new keys.

Please can i get some help identifying this issue.

Many thanks in advanced.
