NegroC230's Requested Info

I think I get why you were asking the question. I think they all use the same manifold.

The 230 and 350 (w203) have the same part number for the manifold

The 300 and 350 (w204) have the same part number for the manifold.

I have attached how to change manifold on the w203 and w204. Also I have attached all part numbers (230, 350, 300, 350)


W203 C230




W203 C350



W204 C300



W204 C350



Hope all this info helps

This is all I could find for the o2 sensor. I couldn't find a wiring diagram.

Hope it still helps.
