SHIP IT it to the DEALER?? (’17 Benz C300 Radio-Camera FAIL….

Owner brought his 2017 Mercedes Benz C300 to PHAD with a complaint of intermittent Radio and Backup Camera at only 75k miles.
This fancy EURO mobile has over FIFTY computer modules onboard!
During the Radio diagnosis I also noticed a strong GASOLINE smell under the hood…kind of concerning.
Will we be able to Diagnose and Repair this fancy Benz?
Or is it going to force us to SHIP IT TO THE DEALER?
