problem #1

Car showed signs well before vehicle started showing codes. When I would start it up the vehicle sounded like a rocket ship was about to take off and shortly after the noise would go away. With no codes Mercedes tried replacing the some ac parts but it didn't help. I just assumed the noise was harmless if Mercedes says nothing's wrong than it must be okay. Then one day I went to turn the car on and it hesitated making all kinds of noise but always started after holding the key in the on position and pushing forward. Car seems to work well once started but I am using more gas which might be related.the check engine light came on afterwards and would turn itself off. After bringing it to Mercedes they state I need a new intake variable camshaft adjustor and it's a good idea to replace the exhaust as well since there's no charge for additional labor since the exhaust adjustor is going to be accessible. My car is at 68,000 miles and well kept this is a mechanical issue with Mercedes in multiple models and years.
