Hello
I would like if you can help me
It's a 2006 e90 320i n46b20

The catalyst was emptied.
Because it was already giving errors.
It was all dust inside.

Now I have some new errors.

2CA3 HO2S heater upstream of cat
29F4 Catalys conversion
29F5 Vatalyst conversion bank 2

In some cases it has also happened to me that when turning on and leaving very soft it tends to turn off.
If I go out a little faster this won't happen.
or if I give it some acceleration before leaving.

Could you guide me what I can try?
I saw fuse number 5 somewhere.
Buy lambda probes.
Thank you
