Misfuel risk Moderate
Larger tank increases severity if wrong fuel is run before drain.
If the engine was not started
Identify fuel type from door label. Full drain before start—especially on diesel.
If the engine was started
Plan HPFP/injector scope on contaminated diesel; gasoline catalyst checks if diesel was run.
Access procedure
- Relieve fuel system pressure per OEM service information (disconnect pump fuse/relay or use scan tool as specified).
- Disconnect the negative battery cable.
- Access the fuel pump module per OEM (rear seat service hole, trunk floor, or cargo area—varies by model).
- Disconnect fuel lines and electrical connectors at the pump module using line-specific tools.
- Drain the tank into approved Class 3 containers; bond/ground per OSHA 29 CFR 1910.106.
- Inspect the tank interior; replace in-tank filter if contaminated or per OEM.
- Reinstall the pump module with a new seal; reconnect lines and wiring.
- Refill with the correct fuel grade; prime the system and check for leaks before road test (Mercedes-Benz procedure).
Notes
- GLE Coupe fuel system parallels SUV—confirm body in XENTRY.
