Mercedes-Benz vehicles require MB-spec 229.5 or 229.51 approved motor oil, and their 7G-Tronic and 9G-Tronic transmissions need MB 236.14 or 236.15 fluid — not available at generic shops. For Lynnwood Mercedes owners, Tom's B&M Auto carries MB-approved oil in stock, uses XENTRY-compatible diagnostic software, and handles air suspension, COMAND, and M272/M273 engine repairs.
XENTRY-compatible Mercedes diagnostic scan reading chassis-specific fault codes, SCN coding verification, and service interval reset. Generic scan tools cannot access Mercedes-specific chassis modules.
MB 229.5 or 229.51 spec oil used in all Mercedes engine services. 7G-Tronic and 9G-Tronic transmission service uses MB 236.14 or 236.15 fluid. Mercedes-specific coolant for all cooling system services.
SCN coding and variant coding performed after any module replacement. Air suspension level calibration after strut replacement. All Mercedes repairs backed by our 24-month/24,000-mile warranty.
Mercedes air suspension failures are predictable — the rubber air bags crack and the compressor wears from compensating. We replace air struts as complete units (air bag, shock, and valve block together) and inspect the compressor, dryer, and supply lines at the same time. Replacing struts without addressing a marginal compressor causes the new struts to fail early.
The M272 and M273 V6 and V8 engines develop a specific timing chain guide failure — plastic guides that crack and fall into the oil pan, causing chain slap and eventually timing failure. We inspect for this on every high-mileage M272/M273 engine and quote the repair before it becomes catastrophic.
Mercedes-specific codes, SCN coding, and module adaptation.
