mercedes c 2.50 2012 check engine
we have checked is there any air leaks in pipes but no air leaks. Also we have changed Air mass sensor and boost pressure sensor.. still engine light comes back, but it disappears when you drive slow or normal.. But it comes back when you go to motorway and gain speed after 60 mph but than later again disappear.
Did any one had similar problem
