Frequently Asked Questions
What is the known issue with the ABC suspension on the R231 SL350?
Active Body Control (ABC) hydraulic leaks are a well-documented concern on the R231 platform. Strut seals and high-pressure hoses can weep fluid over time, triggering a “Visit Workshop” message. This manual covers the full ABC hydraulic circuit, including strut replacement torque specs, pump overhaul, and the diagnostic flowchart for fault codes C2496 and related ABC DTCs.
Is the R231 SL350 related to any other Mercedes models of the same era?
The R231 SL-Class shares its platform architecture and M276 V6 powertrain with the contemporary W212 E350 and C207 E350 Coupe. However, the R231 features a unique aluminum-intensive body structure and the ABC suspension not found on those siblings, so model-specific procedures in this manual are essential.
Does the manual cover the retractable hardtop mechanism in detail?
Yes. The Vario-Roof section includes hydraulic cylinder specifications, fold sequence logic, latch striker adjustment dimensions, weatherstrip replacement, and software-based roof initialization steps — all specific to the 2012–2014 R231 production run.
