ISSUE

Diesel exhaust fluid (DEF) injector crystallization leading to incorrect and unnecessary replacement.

CAUSE

Some crystallization will always be present on the tip of the injector after engine shut down, this is considered to be normal. The crystallization will quickly disappear after the engine is started and the exhaust system becomes hot.

ACTION

Refer to the attached file which shows a selection of crystallization on the DEF injector tip.

These pictures show a level of crystallization present on the tip which will not influence the function of the injector. These pictures are typical of injectors currently being replaced and returned via warranty and when tested are no fault found.

Always refer to the Diagnostic and Testing Section in TOPIx if help is required diagnosing concerns with the Selective Catalytic Reduction (SCR) system. Section 309 - Exhaust System.
