Frequently Asked Questions About Jeep Ecodiesel Services
My Jeep Grand Cherokee EcoDiesel has a "Dealer Service Required" light for the emissions system. Can you help?
Absolutely. This light indicates a fault in the DPF, SCR, or EGR systems. We have the specialized diesel diagnostics to read these codes, perform the required repairs or regenerations, and reset the system—often without a costly dealership visit
I experience a lot of lag and low power in my Gladiator EcoDiesel, especially when off-road. What's the cause?
This is frequently due to a clogged intake manifold from carbon buildup, a sticking turbo actuator, or a failing sensor. Our diagnostics can pinpoint the exact cause, and we perform thorough cleaning or repairs to restore your Jeep's responsive power.
Do you work on lifted or modified Jeep EcoDiesels used for overlanding?
Yes, we do. We service modified Jeeps and understand how aftermarket components interact with the diesel system. We can provide maintenance, diagnose issues specific to modified vehicles, and install performance upgrades suited for overlanding.
How often should the fuel filter be changed on my Jeep Wrangler EcoDiesel?
We recommend a fuel filter change every 20,000 to 30,000 miles under normal conditions, or more frequently if you use your Wrangler extensively off-road or with aftermarket fuel sources. Clean fuel is critical for protecting the high-pressure fuel pump.
