Excellent service. Most shops dont allow customer bought parts to be brought in. With freight delays and specific quality parts needed for these trucks, sometimes customer brought parts are necessary. MDS Diesel gave me no grief and installed the specific parts I wanted in my truck and addressed another issue that I thought was going to be big $$$ but was just rerouting a vacuum hose. I appreciate good, honest and customer pleasing service. I will always recommend to friends and family MDS for their diesel truck needs.

Best diesel around! Thank you Wayne for such great quality service.Bryan/BG Contracting

Nice staff, I am glad to be able to purchase a FASS system locally. Thanks for getting this for me.

Took my truck in for new injectors. They installed the injectors and stand pipes I already purchased. I made an appointment and they had it done in a day like they said. The guys up front were super cool. Definitely going back.

I had MDS fix a air leak on my Class A Diesel Motorhome. They did a great job. The mechanic, Julio really seemed to care about doing what was needed to get me back on the road. That was a pleasant surprise based on experiences over the last couple years getting diesel service in the San Diego area.

One of the best shops in so cal

Chris and Heidi Cole are great people to work for and serve their customers as if they were family. I would work there again and take my trucks without hesitation for service or performance. From chassis and suspension to transmission and heavy-duty trucks they can handle it all.

I brought my truck into MDS..( Chris ) she had a lot of problems, Every one of them got Diagnosed And fixed, New Turbo, new manifold, new ECM... Dealing with Chris, and Robert, was a pleasure.. Very knowledgeable and hardworking mechanics.. very down-to-earth and capable guys, I highly recommend MDS!!! hopefully she runs Great for a long time.. but any New problems with my Truck In the future she will be back in their shop..Thanx guys ..

Wayne is the man. Theres no substitute for experience or customer service. Wayne and MDS have both.
