Absolutely. It is very easy to correct. If you do have the M104, you can do it yourself in a matter of minutes. If I remember correctly, the line runs in front of the filter (towards the nose of the car) and goes under the intake manifold. It is a thin line, and again if I remember correctly is grey in colour. Just run your hand along this line until you find the rubber connector that it is supposed to be seated into. Plug it in to the connector.
