Frequently Asked Questions
Is the M266 timing chain really a problem on the 2009-2011 B180?
Yes. The M266.940 engine in the W245 B180 is known for timing chain tensioner wear, particularly on higher-mileage units. The software includes the complete Mercedes factory procedure for inspecting the tensioner, measuring chain slack, and performing full chain replacement with correct torque specifications.
Does this software cover both left-hand and right-hand drive W245 variants?
Yes. The W245 B Class was sold globally and the software covers both LHD and RHD configurations, including steering rack, pedal box, and lighting circuit differences between markets.
Are interactive wiring diagrams included for the B180’s electrical systems?
Absolutely. Full circuit diagrams are included for engine management, ABS/ESP, airbag/SRS, central locking, climate control, and lighting. The software allows circuit tracing by wire color, connector pin, and component location — identical to the tools used by Mercedes-Benz dealership technicians.
What format is the manual?
This is NOT a PDF. It is authentic Mercedes-Benz OEM dealer software packaged as a VMware Player Virtual Machine. It runs on Windows (XP–11), Mac, and Linux and provides the same interactive diagnostic and repair environment found at authorized Mercedes dealerships worldwide.
