Found one that fit.
It's a shame you have to buy an assortment just to find one that would work for my vehicle. You can't find an OEM one without buying the whole headlight assembly. Oh well.....

Effective
Size: 300 Milliliter
This worked wonders on my car’s performance! After one use, the engine started idling much smoother and the throttle feels more responsive. A very high-quality German-made product.

Great for All Cars but Especially German Cars
Size: 300 Milliliter
I use this in our used VW we bought and it helps keep the carbon build up down with their direct injection feature. I pair it with their oil additive which helps lubricate the rings so they don't stick as much.
