You did not say whether there is or is not a check engine light or any "pending" codes. This is very important info that would be helpful. After that, my next suggestion would be to perform a smoke test to identify the source of a vacuum leak.

If you have 50,000 miles or less, the vehicle is under factory warranty (4 years or 50,000 miles) and the repair will be free. If you are over 50,000 miles, you will need to have someone who has the MB software (or a clone) scan it for you. Without a code, it cannot be diagnosed.

Question Answered: Why does my engine light come on after driving approximately 30 miles?

it's impossible to answer your question until you provide us with the diagnostic codes associated with the check engine light. some parts stores will pull the codes free,
but normally will not get into SRS codes. you may need to pay a shop to diagnose this issue. remember, if the SRS
light is on, your airbags system is inop, so this is a safety issue.
