1. On the engine block:
* Front side of the engine: Check the top or bottom of the engine block, close to the cylinder head.
* Near the oil filter housing: Look near the oil filter housing on the side of the engine block.
* Below the intake manifold: Check the area below the intake manifold.
2. On the engine mounting plate:
* Between the engine and the firewall: The engine mounting plate is usually located on the right side of the engine, near the firewall.
3. On the chassis:
* Driver's side, near the front wheel well: This is less common, but some models may have the engine number stamped on the chassis in this area.
Tips for locating the engine number:
* Use a flashlight: The engine compartment can be dark, so a flashlight will help you see better.
* Clean the area: If the engine number is dirty or obscured, use a brush and some cleaning solution to clean it.
* Consult your owner's manual: The owner's manual for your 190D may have a diagram showing the engine number location.
* Contact a Mercedes-Benz dealer: If you're still having trouble finding the engine number, you can contact a Mercedes-Benz dealer or a qualified mechanic who can assist you.
Remember that it's always a good idea to double-check your findings with your owner's manual or a trusted source.
