A BMW inline-six or turbocharged four out of a low-mileage donor costs a fraction of a dealer replacement, and the engineering doesn't change because it's used. What changes constantly is the chassis code underneath the model name — a 3 Series alone has run as E36, E46, E90, F30, and G20 — so every unit we list is verified against the actual chassis before it's sold, not just the badge.
Send us the year, model, and VIN and our USA-based team confirms chassis code, engine variant, and xDrive configuration before anything ships. BMW electronics also frequently need coding to the receiving car after installation — modules, instrument clusters, and some drivetrain components included — so ask us up front whether yours falls into that category.
Chassis codes, turbo generations, and what needs coding after installation. Need help? Call 1-800-606-1107.
It's BMW's internal platform designation — E90, F30, and G20 are all '3 Series' but share almost no parts. We identify your chassis code from the VIN before matching anything, since the model badge alone isn't specific enough.
The N54 uses twin turbochargers; the N55 moved to a single twin-scroll turbo with direct injection updates. They're not interchangeable, and we confirm the exact engine code off your VIN before sourcing a part.
Some will. Modules, instrument clusters, and certain drivetrain electronics are VIN-tied and need coding to your car via BMW's diagnostic software after installation. Mechanical parts like engines, suspension, and body panels don't. Ask before you order and we'll tell you which category yours falls into.
Yes — xDrive cars run a different transfer case, driveshaft, and often a different subframe than rear-wheel-drive versions of the same model. We confirm drivetrain configuration against your VIN before shipping.
Yes, on an ongoing basis. Classic BMWs have a strong following that keeps donors moving through our network. Call for current availability on your chassis.
If we VIN-matched it and it's wrong, we cover the return and replacement. Every eligible order also carries the 90-day warranty.
