Where to find engine number on BMW e46?

The engine number on a BMW E46 can be found in a few different locations:

1. On the Engine Block:

* Near the front of the engine, on the block itself. Look for a flat surface, usually near the alternator or oil filter. The engine number is typically stamped or embossed into the metal.

* On the right-hand side of the engine block, near the cylinder head. It might be located under the intake manifold, requiring some removal to see it.

2. In the Engine Compartment:

* On the metal plate attached to the inner wing (fender) on the driver's side (left) of the engine compartment. This plate often contains other information as well, such as the chassis number and production date.

3. In the Vehicle Documents:

* Vehicle Registration: The engine number might be listed on your vehicle registration documents.

* Service Booklet: If the vehicle has a service booklet, the engine number should be recorded there.

Tips for finding the engine number:

* Use a flashlight to help illuminate the engine compartment.

* Use a mirror to see areas that are difficult to reach.

* If you can't find it, it's best to consult a mechanic or BMW dealership for assistance.

Important Note:

* The exact location of the engine number may vary slightly depending on the model year and engine type.

* If you're unsure, it's always best to consult your owner's manual or contact a BMW dealership for clarification.
