Yesterday I was driving on the motorway and as soon as I started slowing down for my exit a warning came up, Drivetrain issue and the car has gone into limp mode. I have an F20 125D which I recently purchased. The coolant is at max however the car keeps saying it is low. Can this be related ? If not, what could the issue be? I have took the car to a garage and got it scanned, it also has an Egr issue. I haven't owned the car for long, however I bought it privately so can't go back to the previous owner.
