Gearzaar Valvetronic Actuator Fits BMW N20 N55 – Eccentric Shaft Sensor 11377603979

So, if you're driving a BMW with an N20 or N55 engine and you're getting that rough idle or a check engine light that just won't quit, this might be your fix.

It's a Valvetronic actuator—basically the brain that tells the eccentric shaft how to manage your valve lift.

This one's from Gearzaar, and it's a direct swap for the old part.

The OEM numbers match up: 11377603979 and A2C5328032080.

It's brand new, still in the box, and it comes with a solid 5-year warranty, which is pretty sweet.

No need to worry about shady used parts; this is straight-up plug-and-play.
