Frequently Asked Questions
What is the known balance shaft issue on the M266 engine, and does the manual cover it?
The M266 1.6L fitted to the W245 B170 is known for balance shaft unit wear, which can cause timing chain rattle and oil pressure concerns. The software includes full removal, inspection, and replacement procedures for the balance shaft assembly, timing chain, and tensioner components with OEM torque specifications.
Is the W245 platform shared with any other Mercedes model?
Yes — the W245 platform underpins both the B-Class and the closely related A-Class (W169). While this software is specific to the B170 W245, many chassis and suspension procedures are architecturally similar between the two lines.
Does the software include interactive wiring diagrams for the B170?
Yes. Full circuit diagrams covering engine management, ABS, airbag systems, HVAC, central locking, and lighting are included. The software allows you to trace circuits, identify connector positions, and locate ground points exactly as a Mercedes dealership technician would.
What format is the manual?
This is professional OEM Mercedes dealer software — NOT a PDF. It runs as a VMware Player Virtual Machine and is compatible with Windows, Mac, and Linux systems. It delivers searchable repair procedures, interactive wiring diagrams, and integrated diagnostic flowcharts at dealer level.
