Mercedes-Benz Sprinter (VS30) 2.0 d (OM654) common problems.

Engine / equipment

OM654 2.0 and OM656 3.0 diesel (C, E, S, GLC, GLE, GLS, G-Class from 2016)

Period mentioned

2016–2026

Symptoms

AdBlue or emissions warnings with a start countdown; particulate filter warning; power loss or rough idle from a dirty EGR.

Possible cause described

These are robust engines; faults concentrate in the emissions system. The AdBlue system (injector, NOx sensors and SCR catalyst) sometimes fails, especially in the cold, and the particulate filter and EGR foul if the car mostly does short trips.

Check for the garage

Read AdBlue and NOx sensor codes with Xentry, check the particulate filter regeneration history and how the car is used (short trips).

Cost cited in the source

AdBlue system: approx. €500–1,200; particulate filter: €1,000–2,000A rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: from 100,000 km. This is not a maintenance interval and does not predict a failure.

Engine / equipment

OM654 2.0 diesel in the Sprinter (VS30)

Period mentioned

Intercoolers built before 02/02/2024

Symptoms

Yellow low coolant warning with no leak to be seen; sometimes the engine misfires or surges. Possible codes: P25567B (coolant level too low) and P30040B (temperature sensor after the intercooler).

Possible cause described

The liquid-cooled intercooler (charge air cooler) leaks coolant internally, which reaches the intake and the cylinders. Mercedes-Benz also names two other possible causes: another leak in the cooling system or a modification of the system the brand does not allow. It is described in its XENTRY technical note LI09.41-N-079165.

Check for the garage

Pressure test of the cooling system. If it loses pressure with no visible leak, the garage removes the throttle valve or the charge air temperature sensor to look for coolant inside the intercooler and does a compression test. If confirmed, the coolant is cleaned out of the intake and cylinders and the intercooler (one built after 02/02/2024), glow plugs, oil and filter are replaced.

Engine / equipment

OM654 2.0 diesel in the Sprinter (VS30) with 4th-generation SCR

Period mentioned

Model years 2023 and 2024 (built before 01/08/2024)

Symptoms

Engine warning light on, sometimes with an AdBlue warning, with codes P20F409 (AdBlue consumption too low) or P202E84 (fault of AdBlue metering valve 1, engine side). It happens more with frequent starts and stops.

Possible cause described

According to Mercedes-Benz XENTRY technical note LI49.20-N-079157: a leak in the AdBlue system, an internal fault of AdBlue injector no. 1 (metering valve, engine side) or an air pocket in its line. On model year 2023 and 2024 Sprinters, the design of the AdBlue line causes those air pockets; replacing the tank or the line does not fix it.

Check for the garage

The garage runs the guided tests for those codes, looks for leaks at the AdBlue tank, pump, line and injectors and checks the line does not touch the exhaust. If there is no leak and the injector passes its test, on 2023 and 2024 vans it is enough to reset the AdBlue pump learned values, run the SCR system start-up again and do a test drive of about 30 km; no parts need replacing.
