This is an engine mount produced for the BMW 3 Series E90 Sedan (316i, 318i, 320i) gasoline vehicles, compatible with N45 and N46 engines, with the part code BSG (15-700-208). It is a critical part that secures the engine to the chassis and dampens the engine's vibrations (resonance), enhancing cabin comfort. If the hydraulic/rubber structure inside deteriorates over time, the vehicle will shake excessively at idle, and vibrations will be felt in the steering wheel.
- Direction Warning: This part code is listed as RIGHT (Passenger Side) in standard catalogs. The geometry for the left side is different.
- Vibration Absorber: Damps the vibrations produced by the engine before transmitting them to the chassis.
- Compatible Engines: 4 Cylinder Gasoline (N45B16 / N46B20).
- Quality: Features a reinforced body resistant to heat and engine weight.

Frequently Asked Questions (FAQ)
Will it fit the Left (Driver) side? **Very low probability.** Engine mounts in BMW E90s are not symmetrical. The left side has an intake manifold, while the right side has an exhaust manifold, resulting in different angles and heat shield structures for the mounts. The BSG 15-700-208 code typically corresponds to the **RIGHT** side.
Is it compatible with the N43 Engine (LCI)? In facelifted (LCI) vehicles with N43 engines produced after 2008, especially if they have Start-Stop equipment, the mounts may be different (vacuum type). If you have a vehicle with an N43 engine, you must check based on your chassis number.
Will it be a problem if I only change one? Generally, both wear out at the same time. If you only replace the broken one, the new mount will be too tight, causing all the load to shift to the old mount, which will break it shortly after. It is recommended to change both (Right-Left).
