When the engine itself needs work, you want a shop that does the job right the first time. At Autobahn Service of San Jose, our ASE-certified technicians handle major engine mechanical repair on BMW, Mercedes-Benz, and every Asian and domestic make — from oil leaks and valve cover gaskets to timing components, head gasket work, and engine replacement.

Why It Matters for European Vehicles
BMW and Mercedes-Benz engines have well-known wear points — oil filter housing gaskets, valve cover gaskets, timing chain guides, oil cooler seals — that fail on a predictable timeline and cause expensive secondary damage if they’re ignored. Catching them early, with the correct OEM-spec parts and the factory torque and assembly procedures, is the difference between a contained repair and a major engine job. We’ve done these repairs on BMW and Mercedes vehicles for years and we set the engine back up the way the manufacturer intended.
How Long It Takes & What It Costs
Engine repair timelines vary widely with the job. Oil leak repairs and gasket service are often completed in a day or two; timing components and head gasket work take longer; full engine replacement is a multi-day job. We diagnose first, provide a written estimate before any work begins, and walk you through the options — no hidden fees, no surprise add-ons. Check our specials page for current discounts.
