Frequently Asked Questions
Is the OM654 diesel engine prone to EGR issues on the CLS 220d?
Yes — the OM654 2.0L turbodiesel used in the CLS 220d is known for EGR cooler fouling and DPF clogging, particularly on vehicles used predominantly for short urban trips. This manual includes full step-by-step procedures for EGR valve removal, cleaning, and replacement, as well as DPF forced regeneration and AdBlue/SCR system maintenance to keep emissions systems functioning correctly.
What chassis code does the 2019–2022 CLS belong to, and is it related to any other Mercedes model?
The 2019–2022 CLS 220d rides on the C257 platform, which is the third generation of the CLS nameplate. It shares its MRA (Modular Rear-drive Architecture) underpinnings with the W213 E-Class, meaning many mechanical procedures and component specifications overlap between the two models.
Does the manual cover the AIRMATIC air suspension system?
Yes. The manual includes complete coverage of the optional AIRMATIC suspension system fitted to many CLS 220d builds, detailing compressor diagnostics, air strut replacement, ride-height sensor adjustment, and electronic damping control (CDC) troubleshooting procedures.
