ZF 8HP fluid change - overfill by 0.5L for transmission cooler?

Wondering if anyone who replaced their ZF 8HP transmission fluid followed the step where you overfill with 0.5L of fluid if transmission oil cooler is present.


I believe in the F22 m240i there is a transmission oil cooler present, correct me if I am wrong. I'm going to tackle this service soon and this wasn't clear to me on my research online.


The ZF manual clearly states to overfill by 0.5L if transmission cooler is present, which on the F22 M240i is, but I don't see any videos or DIY guides which follow that step or even state it.


And how do you overfill correctly? You initially fill once fluid starts dripping out, then attempt to put another 500ml in? Probably wont be able to get exactly 0.5L in.
