Frequently Asked Questions
What chassis variants does this manual cover?
Coverage spans the W211 four-door sedan and the S211 estate (wagon) body styles produced for the 2008 and 2009 model years, both equipped with the NGT bi-fuel natural gas powertrain and BlueEfficiency designation.
Which engine and transmission are documented in detail?
The manual focuses on the M271 1.8-liter supercharged four-cylinder engine modified for compressed natural gas (CNG) operation, producing approximately 163 hp. The matched 5-speed automatic transmission is covered in full, including overhaul torque specs and shift-valve service.
Are CNG-specific systems fully covered?
Yes. The manual includes dedicated sections for the high-pressure CNG storage system, pressure regulators, dual-fuel injection strategy, NGT-specific wiring diagrams, and emissions compliance procedures — information not typically found in generic E-Class manuals.

The manual is a fully searchable PDF compatible with Windows, Mac, Linux, tablets, and smartphones. Individual pages or full sections can be printed as needed, and there is no waiting — download begins immediately after purchase with unlimited future re-downloads included.
