ENGINE MANAGEMENT LIGHT TURNS ON AFTER DRIVING AT 70MPH

2004 BMW 320D • 92,000 miles

Hi, I have a BMW 3 series 320 d, 2004 model car. The engine management light comes on when driving on the motorway at around 70 miles an hour. It then stays on for a few days after and then switches itself off. The trigger is almost always hitting around 70mph, any ideas on what the problem could be? Thank you for your time.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
