Truck DPF Repair Services in San Diego, California

Diesel Mechanic Performing DPF Repair on semi truck in San Diego, CA

How Does a DPF Work?

DPFs (Diesel Particulate Filters) were created out of necessity—as emissions standards became more and more strict, truck manufacturers had to think of a solution that wouldn't undermine truck performance. 

. These filters are on the frontlines of lowering harmful emissions by trapping and removing over 80% of NOx particles, which can cause serious damage to the engine and the environment. Despite your DPF’s passive automatic regeneration cycle that burns off soot at frequent intervals, DPFs can become clogged, which can reduce engine performance and cause other problems with your aftertreatment system.

Convenient On-Site DPF Cleaning & Forced Regens

At Quality Mobile Fleet Services, we offer on-site DPF cleaning and forced regeneration services to help keep your operation in compliance with emissions standards. Our state-of-the-art diagnostic equipment and DPF cleaning machine let us gauge what kind of cleaning service you need, whether it’s a forced regeneration cycle at lower levels of trapped soot, or a complete DPF cleaning when soot buildup is over its threshold

In-Shop DPF Repair and Replacements

If the problem isn’t related to the buildup of soot in the filter, come by our repair shop in San Diego, California. We also offer DPF repairs for smaller issues and replacements when your DPF is on its last leg.

Signs Your DPF Is Clogged

It is essential to keep an eye out for signs that your DPF may be clogged, including reduced engine performance, reduced fuel efficiency, turbocharger issues, and the illumination of warning lights on your dashboard. If you notice any of these signs, it is essential to have your DPF checked by a professional as soon as possible.

Boat DPF Maintenance

Do you own a boat or a dinghy? In addition to running a similar engine as commercial trucks, marine vessels also have an equivalent DPF system. That’s why Quality Mobile Fleet Services offers DPF maintenance, including DPF cleaning and forced regens, for a wide variety of boats. If your boat's DPF is completely clogged with black soot, give us a call!

What Our Customers
Are Saying About Us

We had a truck lose power at a receiver, and called them for assistance with a jump start. The mechanic was there in less than an hour and got our truck started and back on the road. Quick and efficient, would use them again.

Igor Kudel

Had excellent experiences with Dave and Jan at QMFS San Diego.  These folks care about their customers and back up their promises with solid mechanics that got one of my drivers back on the road and we have used them ever since when in the San Diego area weekly.

Jan and her lead mechanic were excellent.  They got our Volvo in the shop promptly and got it diagnosed and repair faster and less expensive than the other shops we were quoted.  I fully recommend their commitment to helping companies and people that are in need . Eric Z
