Frequently Asked Questions
Is the M272 balance shaft gear wear addressed in this manual?
Yes. The M272 E35 engine in the 2009–2010 CLS350 is known for premature balance shaft gear wear on earlier builds; this manual covers timing chain and balance shaft assembly procedures, including inspection criteria, replacement steps, and the required torque specifications to restore proper engine timing.
What chassis code does this manual apply to?
This manual covers the W219 chassis, which is the platform underpinning the first-generation CLS-Class. The CLS350 shares this rear-wheel-drive platform with the E-Class (W211) but features unique body and suspension tuning specific to the CLS coupe body style.
Does the manual cover the 7G-Tronic transmission in detail?
Yes. The 722.9 7G-Tronic automatic receives full coverage, including conductor plate diagnostics (a common failure point on this unit), valve body removal, fluid and filter service intervals, and shift adaptation reset procedures.
What format is the manual?
The manual is delivered as a PDF file. It is fully searchable and compatible with any standard PDF reader on Windows, Mac, or mobile devices. Individual pages or complete sections can be printed for workshop use, and your download link is available for lifetime re-access.
