Someone correct me if I am wrong, but this is not necessary for 328i.
Only needed for FI cars like the 335i. |
You are right. I did read about it after I posted this topic. Apparently the N54 engines are directed injected while the N52 engine in our cars are fuel injected through the valves. So the fuel itself cleans the valves and intake area.
