The float test, bmw checks the degree of movement on your crankshaft. If there's too much movement, then there is an issue. Your chain guides should have been retrofitted to the revised ones found on the later models. If you open your oil cap and shine a light down there, you will see the cam chain. Look for scorching or abrasions. Mine had it, along with a high pitched whining noise which I reported to bmw on several occasions.
If you had a 2014 model plus. You would have more peace of mind. But I wouldn't mod the earlier models.
Thanks Samo. I've noticed my car has a very high pitched whining noise that is very intermittent. It comes and goes.
It might not be the issue you bring up, but thought I might mention it. Taking the car into SMG tomorrow.
Then the service will be done in November. All I know is that I can't stand the power delivery of this car anymore hence the need to do a software (stage 1) for now, with a downpipe later for stage 2.
Software will only cost me around R5500, but based on my research can bring the power to about 160wkw or thereabouts for stage 1. Car is about 125wkw right now.
I had a similar thing. When auto stop/start was engaged, and I got to a robot, just before the auto stop kicked in, my car would whistle. Suspected timing chain and guides, got it checked out.. they found nothing wrong though.. quoted me to replace them down the line, if I want to.
Anyway, been months since then, and the problem never came back. Granted, I dont use auto stop/start any more.
To be clear, the high pitched sound does not happen when the car comes to a halt. It happens while driving - when it happens it might last for 3-4 seconds then it goes away ...

Driving my brothers 320i to my 328i. I found you had to work the 320i alot harder and I also missed the extra torque. My consumption was actually lower than his.. Probably because of the better torque curve..
My brain is being pulled in so many directions at the moment. Part of me wants to go the JB4 route, just because it can be taken out.
If I do software and downpipe later, I can't just reinstall the software later without paying another R5500K, so the JB4 has maybe more value than just doing a software - not because of all the other functions, but because I can use it on my next car, whatever it might be.
The whole software/downpipe might bring about more gain, but it costs more if I decide to sell and buy a newer car later, so there are compromises there.
I think, depending on the general car health I can make a more informed decision. I know my turbos (and associated mechanical bits and bobs) were replaced under motor plan, so I have brand new turbos and connecting mechanical bits that should last me a long time.
I'll just have to ask the BMW technician to check the other bits in the car to see if everything is in good working order.
