GPF Regeneration Fault Light
WarningBYD · Engine
What does this warning light mean?
The GPF (Gasoline Particulate Filter) warning light illuminates solid yellow when the filter's soot load reaches maximum capacity, causing increased fuel consumption and reduced engine performance. This indicates that passive regeneration has failed and the vehicle requires active regeneration or professional cleaning at a service centre.

What to do
Take your vehicle to a BYD authorised service centre immediately for inspection. Technicians can perform GPF active regeneration using diagnostic equipment. Do not ignore this warning for extended periods, as this may cause permanent damage to the filter and result in significantly higher repair costs.
