Used or reconditioned?
Given the extreme rarity and high value of these V12 Biturbo engines, reconditioned units are strongly preferred where available to guarantee reliability, though some buyers of older W220/W215 models may opt for used units to keep costs proportional to vehicle value. The M275 and M279 V12 Biturbo engines are highly complex, high-output units where ignition system failures (coil packs, spark plugs) and turbocharger coolant line degradation are known maintenance items. Due to the extreme labour cost of in-situ repair and the engine-out requirement for many common services, failed or high-mileage units are typically replaced complete.
