Frequently Asked Questions
Does the W221 S280/S300 have a known balance shaft gear issue?
Yes. The M272 V6 engine fitted to the S280 and S300 is known for premature wear of the balance shaft gear and idler gear, particularly on vehicles built before late 2008. This manual includes complete timing chain and balance shaft procedures, enabling proper diagnosis and replacement before secondary engine damage occurs.
Does this manual cover both standard and long-wheelbase W221 body styles?
Yes. The W221 platform was offered in both standard-wheelbase and long-wheelbase (S300 L) configurations. Body, interior trim, and chassis procedures in this manual apply to both variants for the 2007–2013 production run.
Are the Airmatic air suspension and ABC systems covered in detail?
Airmatic (pneumatic) suspension is covered in full, including compressor testing, air strut service, and height sensor calibration. Active Body Control (ABC) hydraulic suspension, where fitted, is also addressed within the suspension and hydraulic system chapters.
