Bulletin Summary
To change Diesel Exhaust Fluid (DEF) hose between pump and injector unit. On the vehicles affected by this service bulletin, there is a risk that the heated DEFL hose between pump and injector unit overheats. Investigation has shown that the heat generated by the electric current flowing in the heating wire of the DEF hose could damage the line if the DEF flow is low. To address this issue, Van Hool is conducting a Field Change Program to change the affected DEF hose by an improved hose. We also ask to change the 15A circuit breaker protecting the electric circuit of the heated DEF hose by an 8A type.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
