Check engine light came on. I checked gas cap & retigthened. The light check engine light turned off the next day. Had my bro check fault code, it was P0015 - related to camshaft. Service at dealer, they found 2 camshaft solenoid sensor needed to be replaced.
As an aside, I also reported strong gas odor after fueling. Turns out my tank is leaking. This is a known problem, MB is covering cost under extended warranty. I never received notice of this possible problem...MB should notify customers of all issues related to safety !
check engine light came on. Dealership said it was a $5000 to $6000 repair. Timing and camshaft parts were worn out. This is a problem that mb knows about. Bad design. These parts should not wear out in 45,000k miles on any car. Shame on mb for not recalling.
