Our story
Valerio's Mobile Diesel Repair is a mobile shop for Cummins and heavy-duty diesel trucks around Santa Maria, California. When your rig goes down, whether that is on the side of the highway or parked in your own yard, we come to you with the tools and parts to get it running again.
We handle the jobs that keep trucks on schedule: DPF regens, ECM software updates, and the kind of diagnostic work that separates a quick fix from a repeat breakdown. If a part is not on the truck, we will track it down at will call and finish the job the same day.
Drivers call us because we pick up, show up, and explain what is actually wrong before we start turning wrenches. No guesswork, no runaround, just a truck that gets back on the road.
What customers say
“We contacted Omar for our Cummins and he came out when he said he would to take a look at it. Very respectful and professional. Took care of our truck like if it was his own. Highly recommend him for all your diesel needs.”
“I started using him for all my semi truck needs. He is very honest, reliable and punctual. No B.S. with this guy. He gets your trucks back on the road, no matter what it is: DPF regens, ECM software updates.”
“We were broke down 30 miles south of Santa Maria sitting on the side of Hwy 101. Left a message for Omar who returned our call within minutes. He came out, diagnosed the issue, checked for any other issues, and repaired the problem. He was kind, professional, and did great work.”
