COMMON DEF PROBLEMS. Crystallization: Crystallization can occur in a couple of ways – over-dosing and hard water top ups. Over-dosing occurs when too much DEF is added to the system – the DEF may not fully hydrolyze which can lead to crystalized deposits in the exhaust or injector nozzle. Over-dosing can result from a partially open …
