It has been identified that during production the EGR pipe has been manufactured from incorrect thickness material. Due to the affect of stresses i.e. heat vibration etc on the pipe it can lead to cracking. If there is significant crack there is a possibility exhaust gases could leak. This could cause surrounding parts to deteriorate. If this happens the vehicle will emit black smoke from the exhaust there will be a loss of power and a warning light will illuminate on the instrument panel.
Abhilfe: Recall all affected vehicles and replace to the EGR pipe.
