Frequently Asked Questions
Is the M272 balance shaft sprocket issue addressed in this manual?
Yes. The M272 3.0L V6 in the SL300 is known for premature balance shaft and idler sprocket wear on earlier production runs. The manual includes complete timing system disassembly, inspection criteria, torque specifications, and step-by-step replacement procedures to resolve this failure properly.
Does this manual cover the R230 Vario retractable hardtop system?
Absolutely. The R230 SL300’s electro-hydraulic folding hardtop is covered in detail, including hydraulic circuit diagrams, pump output pressure specs, latch sensor locations, and the calibration sequence required after component replacement or battery disconnection.
Is the Active Body Control (ABC) suspension system included?
Yes. ABC suspension coverage includes hydraulic strut removal and installation, high-pressure pump diagnostics, accumulator pre-charge testing, and system bleeding procedures — everything needed to service this complex active suspension without dealer tooling.
