Due to the tight tolerances on modern diesel engines, contaminants such as water can dilute the lubricating properties of diesel fuel and cause engine damage. For instance, water can lead to acid forming in the fuel system, which can be extremely caustic and harmful to the engine. Contamination of high pressure fuel system components may cause symptoms including, but not limited to, the following:
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.
