What is the firing order for a VW 2.1 engine?

You're likely referring to the VW 2.1L 4-cylinder engine, which was used in various models like the Golf, Jetta, and Passat.

The firing order for this engine is 1-3-4-2.

Let me explain what this means:

* Cylinders: The engine has four cylinders, numbered 1 through 4 (usually starting from the front of the engine).

* Firing Order: This order dictates which cylinder fires (ignites) in which sequence during the engine's combustion cycle.

Therefore, cylinder 1 fires first, followed by cylinder 3, then cylinder 4, and finally cylinder 2. This order is designed to ensure smooth and balanced engine operation.

Note: While the firing order is consistent for the VW 2.1L engine, some older models might have slight variations. It's always best to confirm the specific firing order for your year and model in a repair manual or online resource like the Volkswagen Owners Club forum or similar sites.
