Frequently Asked Questions

Is the OM651 balance shaft failure covered in this manual?

Yes. The OM651 engine’s balance shaft assembly — a known weak point on early production GLK250 BlueTec models — is fully documented, including wear diagnosis, gear replacement procedures, and updated torque specifications to help prevent repeat failures.

Does this manual cover the X204 platform shared with other Mercedes models?

This manual is specific to the GLK250 BlueTec 4Matic on the X204 platform. While the X204 underpins multiple GLK variants, the procedures here are tailored to the GLK250 BlueTec’s diesel powertrain and 4Matic hardware, not petrol-engined X204 derivatives.

Are AdBlue and emissions system procedures included?

Absolutely. The manual covers the full emissions system for the GLK250 BlueTec, including the selective catalytic reduction (SCR) system, DEF/AdBlue pump and injector service, NOx sensors, EGR valve maintenance, and diesel particulate filter regeneration procedures.
