Can I shut off my engine during a regeneration?

Under normal circumstances an engine can be shut off during a regeneration without any harm to the DPF. Once the engine is shut down, the conditions that support regeneration will subside and regeneration will cease. However, caution must be exercised when parking a DPF equipped vehicle to ensure that the exhaust outlet is not exposed to any combustible substances or materials that could be damaged or catch fire by exposure to excessively high temperatures such as shop ceilings, trees and grass etc.
