What We Do: DPF Troubleshooting, Cleaning & More
At Detroit Diesel Specialists, our experts have hands-on experience to catch the issue without any guessing. Here's how we help:
DPF Troubleshooting
First, we run a full diagnostic. We check your truck's fault codes, pressure readings, and sensor data to figure out exactly why your DPF isn't doing its job.
DPF Regeneration Service
If your filter isn't cleaning itself like it should, we recommend a safe DPF regeneration service right here in the shop. It's a controlled process that burns off all that built-up soot.
DPF Cleaning with Our In-House Machine
If your DPF is still clogged with soot or ash, we'll remove the DPF and run it through our heavy-duty DPF cleaning machine. This will clear out stubborn soot and ash, and bring the filter back to near-new condition.
DPF Replacement or Repair
If your DPF is beyond cleaning—cracked, melted, or just too far gone—we can replace it with a quality part and make sure your entire emissions system is running properly.
How to Prevent DPF Problems?
Good habits can extend the life of your DPF:
Avoid idling for long periods
Use high-quality diesel fuel and low-ash oil
Don't skip regular maintenance and fluid checks
Pay attention to regen cycles and warning lights
Get a DPF cleaning every 150,000–200,000 km, depending on usage

Frequently Asked Questions
How do I know if my DPF is clogged?
If you notice loss of power, more fuel usage, warning lights, or thick exhaust smoke, your DPF might be clogged. A professional diagnosis will confirm it.
What is a DPF regeneration service?
It's a process that burns off trapped soot from the filter using heat. We run this safely at our shop when your truck can't do it on its own.
Do I need a new DPF if mine is clogged?
Not always! In most cases, we can clean it using our DPF cleaning machine and restore it like a new condition.
How long does DPF troubleshooting and cleaning take?
Basic diagnostics take about an hour, and full DPF cleaning can usually be done the same day. We work fast to minimize your downtime.
