How can I fix my Mercedes ml270cdi auto?

When I am driving on the motorway the car will not go over 80mph and this is a new problem that has not occurred before so I don't know how to fix it. Does it have anything to do with the air mass filter? Thank you

Best talking in specilist forums.

And use Google for yourself.
