Preee Posted April 4, 2012 Share Posted April 4, 2012 A cog with exclamtion mark i think is powertrain , i would be inclinded to take it to the dealer and get it checked out Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted April 4, 2012 Share Posted April 4, 2012 Yep powertrain fault. You may find that you will end up getting the limp mode coming up. It would have logged a fault code on your system which will point in the right direction. It could be Mass Airflow Sensor, injectors, and if a diesel the glowplugs and/or glowplug relay. Best diagnosed by a reputable garage. If the light is steady then it's not going to go bang suddenly, but if it starts to flash then i recommend you stop as soon as possible/safe to do so and get it looked at immediately.
