2019–2025 Mercedes Sprinter Fuel Capacity Recalibration Module

Calibrate Your Sprinter’s “Distance to Empty” Reading for Extended Fuel Tanks

If you’ve upgraded your Mercedes Sprinter van (2019–2025) with a larger fuel tank — like the 40, 45, or 47-gallon S&B tank — your dashboard’s “Distance to Empty” (DTE) reading will no longer be accurate. That’s where this Fuel Capacity Recalibration Module comes in.

This module plugs inline permanently with the EIS (Electronic Ignition Switch) to update your fuel system’s DTE calculations, ensuring your van’s fuel range display correctly matches your new tank size. It also adds the J51 fuel gauge optimization if your Sprinter does not already include it from the factory.

Stop guessing your remaining miles — this recalibration tool gives you accurate range readings, improved fuel management, and total confidence on every trip.

Key Features

✅ Accurate DTE (Distance to Empty) Adjustment

Automatically recalibrates your Sprinter’s fuel system to display correct distance-to-empty values when using extended-capacity tanks.

Why You Need It

When you install an extended fuel tank, your factory fuel gauge and DTE readings are still calibrated for the stock tank. This results in incorrect range estimates and early “empty” warnings.

The Fuel Capacity Recalibration Module corrects this issue by syncing your Sprinter’s onboard system with your new tank’s capacity — ensuring accurate readings and worry-free long-distance driving.
