AG Diesel Repair is proud to be a family owned business that stands behind each and every auto repair, truck repair, or diesel repair we make. It is our strong belief that taking care of you, the customer, and your vehicle is our #1 priority. To do this, we provide you with only the best technicians to work on your vehicles. Our team is factory trained to deliver exceptional service, plus, we're certified by ASE, ASA, and BOSCH.  You will come in as a customer and leave as a friend!

We offer automotive/truck service and repair for Northwest Oregon and Southwest Washington, including Portland, Vancouver, and Oregon City. We use only top quality parts that meet or beat original equipment manufactured parts standards. If we cannot provide you with a better part, we will use the OEM part. 

All of our work is backed by a 12-month or 12,000-mile guarantee, or better, depending on the part installed. We take the time to research the cause of the vehicle break-down, so that way we can not only fix the problem but also fix the cause of the problem. Most of the time, this involves a better than OE maintenance program. 

From brakes and auto glass repair to exhaust and suspension system work, we can take care of your vehicle's needs, no matter its make or model. Bring your vehicle into us when you need routine maintenance like an oil change, or come to us when you need diesel truck repair in the greater Portland region. While you wait for your car or truck repair, enjoy our comfortable waiting room, complete with free coffee and free Wi-Fi. We also offer a free customer shuttle.
