Diesel Particulate Filter Service
Diesel Particulate Filter (DPF) cleaning, service, and replacement in Franklin, TN to keep your truck running clean and legal.
The Diesel Particulate Filter (DPF) is a critical part of your truck's emissions system, capturing soot to keep your exhaust clean and your truck compliant. But when a DPF gets clogged or the regeneration system fails, it can send your truck into limp mode, kill your power, and leave you stranded. At Down Home Diesel in Franklin, TN, we service, clean, and replace DPF systems on light-duty diesel trucks.

Frequently Asked Questions
Can you fix a diesel truck stuck in limp mode from a DPF problem?
Yes. DPF and DEF issues are a common cause of limp mode. We diagnose the specific cause and restore normal operation.
Do you clean or replace DPF filters?
Both. Depending on the condition, cleaning may resolve the issue, while a heavily damaged DPF may need replacement. We'll advise the best option.
Why does my DPF keep clogging?
Frequent short trips, failed regens, or underlying engine issues can cause repeated clogging. Our diagnostics identify the root cause, not just the symptom.
