Chery Tiggo 7 Pro DPF regeneration failure — diesel models
The diesel particulate filter warning light illuminates and the vehicle enters limp mode. The 1.6T diesel Tiggo 7 Pro requires regular motorway-speed driving to initiate passive DPF regeneration. Vehicles used primarily in urban stop-start conditions experience rapid DPF blockage. A forced regeneration cycle at a dealer clears the fault. Installing a wider exhaust temp sensor bracket resolves premature regeneration cut-off.
