UView Emissions System Cleaner

Carbon and soot are the natural by-products of combustion, and in an exhaust gas recirculation (EGR) circuit they can accumulate until airflow is restricted and the engine starts to run poorly. UView's approach to this problem is the MotorVac DieselTune EGR System Cleaner (part number 400-0280), a professional-grade formula designed to clean the EGR circuit without the labor of pulling parts apart.

What the DieselTune EGR System Cleaner Does

This cleaner is formulated to dissolve stubborn carbon and soot deposits in EGR valves, passages and intakes. The goal is to clean the entire circuit, which can eliminate the need for EGR tear-down and part replacement. The manufacturer also lists variable geometry turbocharger (VGT) vanes among the components it addresses, which matters on modern diesels where sticky vanes can hurt boost response. Its non-corrosive formula is intended to preserve engine parts while it works, and it is made in the United States.

Typical benefits of a clean EGR circuit include:

• Smoother idle and restored airflow through the EGR system
• Lower exhaust emissions as the system recirculates gases properly
• Better engine efficiency and throttle response
• Reduced risk of costly repairs from clogged EGR components

Designed to Work With the EGR Cleaning Tool

A distinctive feature of this product is that it is built to pair with UView's MotorVac 500-0170M EGR Cleaning Tool. That makes it a good fit for shops and serious DIYers who want a repeatable, controlled service procedure rather than simply adding a bottle of additive to the fuel tank. Using the cleaner through a dedicated tool lets the solution reach the EGR passages directly, which is where deposits do the most harm.

Part of UView's Diagnostic and Service Heritage

UView began with ultraviolet leak detection for automotive air conditioning systems and has grown into a respected name in leak detection, dyes, coolant tools and injection systems. Its MotorVac line extends that service-oriented thinking to engine and emissions maintenance, alongside products like CarbonClean fuel system cleaners. The DieselTune EGR cleaner reflects that same professional-shop focus: a targeted chemistry matched to a specific service task.

Choosing an EGR Cleaner

When shopping, consider the following:

• Engine type: This formula is aimed at diesel EGR systems where carbon and soot buildup is a known issue.
• Symptoms: Rough idle, reduced power, or emissions-related warning lights can point to a restricted EGR circuit.
• Application method: If you plan to use the matching 500-0170M tool, confirm compatibility before purchasing.
