Used OEM parts cost a fraction of what a dealer charges for new ones, and on a 3 Series the gap is wide. A used ABS module, headlight assembly or automatic transmission from the right donor car can save you hundreds of dollars compared with buying new. For an engine, the savings are larger.
Price is only part of it. Buying a BMW part by model year alone is risky. In 2012, a 328i could be an F30 with the N20 four-cylinder or an E92 coupe with the N52 six, and the engine bay, wiring and sensors are completely different. We match each part to your VIN, so you get the part that fits your car, not one that is close.
For E36 and E46 cars, new supply is thinning. Used parts are often the only way to get a correct original BMW part instead of a lookalike. That matters on a car where a cheap substitute can bring back the warning lights you were trying to fix.
You also know what you are getting. Every BackToRoad part is inspected and tested before it is listed, then inspected a second time within 24 hours of shipping. Each one is covered by a 30-day warranty, and the details are on our warranty page.
We ship across the United States and Canada, to your door or straight to your mechanic, and a parts specialist can answer fitment questions at 1-800-608-3868. Reusing a working part also keeps it out of the scrap pile, which is a good reason on its own to buy used.
Most Requested Used BMW 3 Series Parts
These are the parts BMW 3 Series owners search for most. Use the parts locator tool at the top of the page, or call 1-800-608-3868 if you want a specialist to look with you.
Used BMW 3 Series engines
Owners ask most often for the N52, N54, N55 and N20, along with the M54 for E46 cars and the B48 for newer ones. Fitment depends on the chassis, engine code and sensors, so search with your VIN. Ask what is included with the engine, such as accessories and wiring, before you order. You can browse our used BMW 3 Series engines directly.
Used BMW 3 Series transmissions
Demand covers the ZF five-speed automatic in the E46, the six-speed automatics in the E90, and the eight-speed automatics in the F30 and G20, as well as manual gearboxes. Manual cars also need the flywheel and drive shaft to match. A transmission should line up with your engine and drivetrain, including xDrive cars that use a transfer case.
Used BMW 3 Series ABS and DSC modules
ABS modules for the E46 and E90 are among the most common requests. A failed module can bring up ABS, brake and stability warning lights at once. Ask whether the module needs coding to your car after installation.
Used BMW 3 Series ECUs, instrument clusters and throttle bodies
Engine control modules, instrument clusters and speedometer clusters are in steady demand, especially for E36, E46 and E90 cars. Throttle bodies are popular on cars where an idle or stalling problem points that way. Because these parts are often tied to the car, tell us your VIN so we can confirm the match.
Used BMW 3 Series headlights and tail lights
Headlights from the F30 and G20 are a frequent request, since a cracked housing or failed LED unit gets expensive new. Halogen, xenon, adaptive and LED versions are not interchangeable, and pre-facelift and facelift cars differ. Side view mirrors and tail light assemblies are available for the same generations.
Used BMW 3 Series steering and suspension parts
Steering racks and columns, upper and lower control arms front and rear, spindle knuckles, stabilizer bars, struts, shocks, coil springs and rear stub axles are all part of the usual list. On a car that drives well otherwise, worn suspension parts are often what makes it feel tired. Used OEM parts let you restore it without a dealer-sized bill.
Used BMW 3 Series driveline parts
Differentials, ring and pinion sets, axle shafts and drive shafts are regular requests, along with transfer cases for xDrive and xi models. The ratio and the drivetrain both have to match your car, so use your VIN to confirm.
Used BMW 3 Series engine and climate components
This group covers radiators and condenser fan motor assemblies, AC compressors, condensers and evaporators, blower motors, alternators, power steering pumps, cylinder heads, intake and exhaust manifolds, and oil pans. Cooling system parts are in demand on older cars, where age-related leaks are common.
