California’s Diesel Emissions Specialists: On-Site DPF Maintenance & More!

At Quality Mobile Fleet Services, we’re proud to be emissions specialists. We offer a range of on-site DPF maintenance services to help keep your operation compliant with emissions standards. This includes:

DPF Repair & Replacement

Whether your truck’s DPF is damaged or has reached the end of its life cycle, we're here to provide a reliable solution. We source and stock top-quality DPFs from reputable brands and provide a range of on-site and in-shop repair services for the entire emissions system, including gaskets and clamps. This will help prevent leaks that could lead to reduced efficiency or increased emissions.

DPF Forced Regenerations

Are your passive or active DPF regens not doing the job? Is your DPF lamp not shutting off? These are telltale signs that you need further action, as the soot buildup in your DPF is too high.

Using our specialized diagnostic tools, Quality Mobile Fleet Services can initiate and perform forced regeneration cycles on-site. This process overrides the soot accumulation calculated in your vehicle’s ECM, thus burning any excess (and stubborn) soot.

California’s Best DPF Cleaning Services

If a forced DPF regen isn't enough, our robust cleaning packages will do the job. Quality Mobile Fleet Services offers the best DPF cleaning services in California!

Our state-of-the-art DPF cleaning machine utilizes a combination of the Air Knife technique, also known as bake and blow cleaning, and an advanced chemical solution flush to deliver exceptional results. If you want to go the extra mile, our Level 4 package adds ultrasonic cleaners to the process, which can clean your filter up to 98% of its original capacity.

Boat/Vessel 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 soot, give us a call!

Frequently Asked Questions (FAQ)

How Do I Know My 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.

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. 

DPFs 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.

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.

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
