Defect
On large trucks whose fuel system has been converted from diesel to CNG, the material and welding method used for the EGR pipe are incorrect. Vehicle vibration may cause cracks to develop at the EGR pipe flange. If use continues in this condition, the cracks at the EGR pipe flange may propagate, resulting in an exhaust gas leak.
Corrective action
On all vehicles, replace the EGR pipe with the corrected/revised part.
