Diagnostics & Electrical Repair

Diagnostics is an essential aspect of truck maintenance, and Quality Mobile Fleet Services has the expertise to provide reliable and comprehensive diagnostics and electrical repair. Proper diagnostics can help identify underlying problems with your truck's systems, prevent costly breakdowns, and improve fuel efficiency, ultimately reducing operating costs. By investing in diagnostics and electrical repair, you can ensure your truck performs at its best and avoid unexpected downtime.

DPF Cleaning, Forced Regen & Replacement

Quality Mobile Fleet Services also provides DPF cleaning, forced regeneration, and replacement services. Diesel particulate filters (DPF) are an essential component of a truck's emissions system, helping to reduce harmful pollutants. However, DPFs can become clogged over time, leading to poor performance and increased emissions. With our on-site or in-shop DPF cleaning services, Quality Mobile Fleet Services can restore your DPF to its original condition, ensuring optimal performance and reducing emissions.

EGR Valve And Cooler Replacement

We also offer EGR valve and cooler replacements. The EGR system is a critical component of a truck's emissions system, and problems with the EGR valve or cooler can lead to decreased performance and increased emissions. Quality Mobile Fleet Services can diagnose and replace faulty EGR valves and coolers to keep your truck running efficiently and reduce emissions.

Engine Repair & Rebuild

In addition to these services, Quality Mobile Fleet Services provides engine repair and rebuild services. Our experienced mechanics can work on engines from a range of manufacturers, including Detroit, Cummins, PACCAR, Volvo, GM, Ford, Chevrolet, and more. Whether you need routine maintenance or a complete engine rebuild, Quality Mobile Fleet Services has the expertise and resources to get the job done.

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
