Wonder if one of the UK members can check something for me?

I have tried to see if both LHS and RHS valves open on cold start by doing the following:
Open Car
Press start
select Sport+
Push down on accelerator
Start Car

When I look down LHS valves are fully open, but on RHS they are barely open. Wondered if I have faulty valves on RHS, car only done 700 miles so far.

Would someone mind doing the same and reporting results?

Cheers

anyone?

I am in the US but I confirm this for my 2022 X4MC. I did those steps on my 2021 X4MC, both valves opened, pulled the fuse and they stay open. No matter what I did in the 2022 X4MC the one valve remained almost all the way closed.

That trick worked on the previous generation of M for a loud start (S55 engine), but I feel like I read that doesn't work on the current generation. I could totally be wrong though.
