Issues with C280
1. Engine very noisy at start up for about 30 seconds.
2. Navigation system is a total lemon often giving wrong instructions eg right turn where there is no right turn signpost.
3. Once engine has reached operating temperature there is constant sound inside the cabin similiar to a jack hammer at a distance. As per MB technician it is a noisy recirculating valve.
4. Auto diming rear view mirror is too dark.
5. Side mirror images are too distorted for driver side.
6. Sound system does not store the last volume .
7. Sun roof stutters on opening and closing
About the Navigation. Probably maps need update.
Sound system does not store the last volume? not sure. probably a difficult fix or no fix.
