FAQs

How Can I Get EGR and DPF Repair?

Is It Safe to Drive With a Bad EGR System?

Not for long. A faulty EGR system can reduce engine performance, increase emissions, and eventually cause damage to other components. It’s best to have it inspected and serviced immediately.

What Are the Signs of a Clogged DPF?

A clogged DPF can cause slow acceleration, poor fuel economy, excessive regens, or dashboard warning lights. If ignored, it can trigger limp mode or complete derate. Cleaning or replacing it is essential.

509 Roadside put in a left foot pedal, brand new brakes, and rotors and rear drums on my car. Also checked all fluids and cleaned engine bay. They were fast, friendly, and went way above and beyond for me. I would give these guys 20 stars if I could!

Erin Walkup

Joseph did a great job replacing a small engine for us. He searched, bought and replaced it for us while keeping us informed every step of the way. With great pricing and service, we will continue to utilize him in the future for our needs.

Mickey Burk

My car broke down and Joe found me stranded. He called a tow truck immediately and waited with me, I told him I thought my alternator burned out and he confirmed that was the case as soon as he walked up. He had the car fixed first thing in the morning and his rate was very reasonable. Joseph is a great person and an amazing mechanic. I highly recommend his services.

Devon M

Totally helped me out of a jam. Last Wednesday 2/26/25 late in the day, my 2011 Isuzu Blue Bumper Box truck had a red check engine light go off. You guys were my angels. Thanks so much for clearing the code and getting my truck back on the road. It made it all the way to Spokane and back to Seattle.

Bobbi Gerlick

These guys got me in to their shop on short notice and found my electrical problem quickly. Can’t thank them enough! I will call them again if I need help in the area!!

Jon William

509 Roadside is amazing. I was driving my truck and was in the area with an airbag broken on my trailer. I called 7 different shops within 100 miles of Moses lake around 1pm on a Thursday 3/13/25 and 509 was the only one to answer. Not only did they answer but they took the time to find the correct airbag and get me safely back on the road at a very reasonable price! It was a great experience and I will definitely be using their services again if I’m ever in need.
