The company found the possibility for exhaust gas recirculation (EGR) cooler inlet pipes – or the pipes that connect the EGR valve to the cooler – to crack or break. The worst-case scenario is that if the pipes fail and aren’t repaired, the air cleaner and inner fender may be exposed to hot exhaust gases with the potential of them causing a fire.
Volvo has had reports of such failures causing some heat damage to inner fenders and air cleaners on a number of trucks. There have been reports of two instances of fires caused by the condition, according to the manufacturer. No one has been injured in any of these instances.
Volvo is presently in the process of sending letters to affected truck owners explaining the situation, instructing them on precautions to be undertaken until repairs are made and letting them know how and when to have repairs made by their Volvo Trucks dealers.
