nope. the airbox on the crd has 2 plugs on it. 1 plug is the ambient air pressure, its the smaller sensor at the back. the other plug is just on the hose leading to the turbo, that is the MAF plug, its four wires, unplug it and reset your error codes and start up and see if your vehicle runs and drives normal, except you will get a p0101 code eventually.
