HELP!! Just changed the air bags on rear of my 99 2,5D and cleverly snapprd the arm off the N/S/F valve.After fitting a new one will it need plugging in to a lap top or just fit it and off I go??
Thanks in advance.

Well i would just fit it and see, if it requires recalibration it will throw up a EAS fault on the dash, if you have not started the vehicle since you fitted te bags start the engine and leave it running with the door open for about 10 minutes for the compressor to fill the tank then get in the vehicle shut the door then press the EAS button to rais the vehicle.
