About MDI Trucks Northern Colorado
Owners dealing with DPF cleaning needs or Cummins-specific diagnostics can turn to MDI Trucks Northern Colorado, which handles both mobile service calls and shop-based repairs for diesel engines. Drivers from Frederick, Berthoud, Johnstown, and Dacono rely on the shop's willingness to come to them. Located in Longmont, Colorado, at 4328 Hilltop Rd, the business combines Cummins certification with on-site service capability, meaning a diesel owner can often avoid a trip to the shop entirely. Call (970) 535-4550 to arrange DPF cleaning or mobile diagnostic work.

Amazing honest and quick service thanks to Allen and his team, highly recommended!! Even though I live in Hawaii and need extensive work done on a truck I purchased Allen treated me as I was his only customer and as if I was his neighbor, I'll definitely use them again.🤙🏼 ...
