Diesel Emissions Testing & Repair in Littleton, CO
At Hinsdale Automotive, we specialize in diesel emissions testing and repair for all types of diesel vehicles. Located in Littleton, Colorado, we’re a family-owned and operated shop with certified mechanics, honest service, and a strong reputation in the community.
Diesel Emissions Testing Done Right
Diesel vehicles require a different approach to emissions testing, and we’ve got the tools and experience to do it right. Our in-house dynamometer allows us to simulate real driving conditions, giving us accurate results and helping pinpoint any issues quickly.
If your vehicle didn’t pass emissions, don’t worry. We’ll find out why and make the necessary repairs to help you get back on the road—legally and reliably.
What Makes Diesel Different from Gas?
Diesel engines are powerful and fuel-efficient, but they also require specialized care, especially regarding emissions.
Here’s how diesel repair and emissions testing differ from gas-powered vehicles:
Stricter Emission Standards
Specialized Components
Our experts repair and maintain manual and automatic transmissions.
Complex Diagnostics
These systems can get clogged, fail, or malfunction—causing your vehicle to fail emissions or run poorly if not properly diagnosed and repaired.
That’s why you need a team that understands diesel and has the right tools to service it. At Hinsdale Automotive, we’ve got both.

Frequently Asked Questions
What are the most common diesel engine repairs?
Why is a DYNO machine important for diesel diagnostics?
Our in-house dynamometer (DYNO) is a specialized piece of equipment that simulates real driving conditions while the vehicle remains stationary. It allows us to:
- Accurately diagnose performance issues
- Measure emissions under load (as required in Colorado)
- Pinpoint problems that basic diagnostics might miss
This makes it an essential tool for diesel diagnostics, especially when it comes to emissions testing and repair.
How often should I service my diesel engine?
While each vehicle is different, here are general service intervals for diesel engines:
- Oil & filter changes: Every 5,000–7,500 miles
- Fuel filters: Every 15,000–30,000 miles
- Air filters: Every 15,000–30,000 miles
- Glow plugs & injectors: Inspected around 100,000 miles
If you use your diesel for towing, hauling, or commercial use, more frequent service may be needed. We can create a service schedule that fits how you use your vehicle.
What should I know about owning a diesel vehicle in Colorado?
Colorado’s unique conditions and regulations mean diesel vehicles face a few extra considerations:
- Stricter emissions testing (especially in the Denver metro area)
- High-altitude driving can affect performance and the air/fuel mixture
- Cold winters require attention to diesel gelling and cold-start issues
Our team is well-versed in Colorado diesel requirements and driving conditions, so we can help you avoid common issues and keep your vehicle running its best.
