How do I know if my DPF is clogged?

A clogged DPF often triggers a check engine light, reduces power, and may cause frequent regeneration cycles or poor fuel efficiency. You may also notice excess soot, rough idling, or your engine entering limp mode.

Can a faulty EGR valve damage the engine?

Yes. A malfunctioning EGR valve can lead to excess combustion temperatures, which may cause engine knocking, head gasket failure, or turbo damage. Timely repair is essential to prevent long-term damage and maintain emissions compliance.
