BMW is synonymous with luxury, performance, and engineering excellence. But like all vehicles, BMWs eventually require engine or transmission replacements — especially as mileage adds up. Whether you’re a car enthusiast restoring a project car or simply trying to save money on repairs, buying a used engine or used transmission is a smart and cost-effective move.
In this comprehensive guide, we’ll explore the top options for sourcing reliable used BMW engines and transmissions. We’ll also focus on specific models like the 2013 BMW 550i, 2012 BMW 750i, 2017 BMW 330i, and popular transmission models from 2011 to 2007.
Why Choose a Used BMW Engine?
A used BMW engine for sale can save you thousands compared to a new or remanufactured one. Many engines come from low-mileage donor vehicles, often due to accidents or trade-ins. These engines are tested, cleaned, and sold by reputable salvage yards or online auto parts retailers.
Benefits of buying a used BMW engine:
- Cost-effective: Save up to 50–70% over a new engine.
- OEM Quality: You’re getting original equipment directly from BMW.
- Environmentally Friendly: Reusing parts reduces waste and conserves resources.
- Availability: Engines for specific models are often easy to find.
Popular Used BMW Engines for Sale in 2025
Let’s explore some of the most sought-after BMW engines currently available in the used parts market.
1. 2013 BMW 550i Engine for Sale
The 2013 BMW 550i features a powerful 4.4L twin-turbocharged V8 (N63). While this engine offers thrilling performance, it’s also known for requiring careful maintenance. A used engine can be a great solution for owners facing serious engine issues like valve stem seal failure or oil consumption problems.
When shopping for a 2013 BMW 550i engine, make sure it has been thoroughly inspected and ideally reconditioned or low mileage.
2. 2012 BMW 750i Engine for Sale
The 2012 BMW 750i shares a similar 4.4L N63 engine as the 550i. Due to its premium status and high cost of dealership repairs, many 750i owners turn to used engines when the original engine fails. Look for units with under 100,000 miles and a good warranty for peace of mind.
3. BMW 335i Engine for Sale (2007–2011 models)
The BMW 335i (especially from 2007 to 2011) is a fan favorite thanks to its turbocharged inline-6 engines, the N54 and N55. These engines deliver both power and smoothness but may suffer from turbo and injector issues. A used BMW 335i engine for sale can be a solid investment if the original is beyond repair.
When searching, verify whether the engine is an N54 or N55 to ensure compatibility with your model year.
4. BMW 550i Engine for Sale (Multiple Years)
In addition to the 2013 version, the BMW 550i engine for sale has seen several iterations across model years. Whether you’re looking for a 2011, 2014, or 2015 model engine, make sure the used engine you’re buying has the correct specs for your chassis and electronics.
5. BMW 330i 2017 Engine for Sale
The 2017 BMW 330i comes with the B46 2.0L turbocharged four-cylinder engine. It’s known for being relatively efficient while still sporty. A used BMW 330i 2017 engine is a practical replacement choice and tends to be more affordable than V6 or V8 units.
Used BMW Transmissions for Sale
In addition to engines, used BMW transmissions are in high demand, especially from years where electronic or mechanical issues are common. Transmission swaps can restore drivability at a fraction of the cost of rebuilding or replacing at the dealer.
Top BMW Transmission Models for Sale
1. 2011 BMW 335i Transmission
If your 335i is experiencing slipping gears, hesitation, or fails to shift properly, a used transmission can bring the vehicle back to life. This generation commonly used the ZF 6HP or 8HP automatic transmissions — both durable when maintained well.
2. 2006 BMW 530xi Transmission
The 2006 BMW 530xi transmission used a 6-speed automatic transmission (ZF 6HP19), known for smooth shifting. A used transmission is often the best repair solution for this model, as rebuilding costs are high.
3. 2007 BMW 335i Transmission
Like the 2011 model, the 2007 BMW 335i engine for sale used either automatic or manual transmissions. Manual options can be harder to source, but they’re often in good condition if pulled from enthusiast-owned vehicles.
