Problem with a VAUXHALL ZAFIRA 1.9L CDTI 2009 42K

Lack of power and engine management light on. Fault code stored P242F diesel particulate filter blockage/ash accumulation, suspect particulate filter blocked. The engine oil was also checked which was excessively overfilled due to contamination from diesel fuel.

The fault was cured by using Forté Clean & Protect, 45-minute Forté New Generation Engine Flush adding Forté Oil System Protector to the new oil and Forté DPF Cleaner and Regenerator and Forté Diesel Specialist Injector Cleaner added to the fuel tank. The car was then taken for a 20-mile road test at 40-50 mph to allow regeneration of the particulate filter.
