Check it carefully.
You must select OCE, then switch off radio, and switch off ignition for the setting to be properly saved.

I've changed many BM53 radios from Japan to Oceania, and they all worked, and AM is always 9kHz steps.
Well you could well be right. When I was looking in to it I found that my car should have option S825A radio Oceania, part number 65126988276 but earlier this year it was replaced under warranty with what I think to be the Japanese version, L807A part number 65126976962. However when you do a search on this new part number one search on the ETK says it is for Oceania

and the other says it is for Japan

So therefore it could be wrong, but the service section of the radio says it is tunes to Oce, but it counts in multiples of 10MhZ.

Both P/Ns are in the ETK under Japan. The 276 is the newer number which superceeded the 962 number.

If it was replaced under warranty, then go and see them and get BMW to fix it.

An AM radio that tunes in 10kHz steps is simply WRONG for Australia.
Compare to every other BMW in the country and you will see that all other BMWs tune in 9kHz steps

As it is a warranty issue, make a complaint and demand the dealer fix it.

Aynway, regardless of part numbers, the BM53 covers Japan, Oceania and USA. It can be reprogrammed to any of these regions.

If you are positive the reprogramming is done correctly (check it again!) then go back to the dealer and advise it is faulty.

I've just checked my setting in the service mode and I have got the following:

Serial number: 46126548
Software Version: 03-06 48
GAL 5
F15 Q15 0000
DSP: 0
TP Volume: 0
Area: set on OCE but I can also choose Jpn, USA & Canada
AF: MAN

For your info:
GAL 5 = speed dependent volume setting
F15 Q15 0000 = FM signal strength 15 (max), RDS quality 15 (max)
DSP: 0 = no DSP detected (fitted) to vehicle
TP Volume: 0 = Traffic Announcement volume set to 0
Area = Area, eg OCE
AF: MAN = RDS alternative frequency mode, I normally set to Auto.

If you are set to OCE but still tune in 10kHz steps then do this:

1. Set to Japan. Switch off and turn key off. Turn back on, check that Japan is OK (FM 76-90, AM 9kHz steps)

2. Now set to OCE. Switch off and turn key off. Turn back on, check that OCE is OK (FM 88-108, AM 9kHz steps)

Maybe a focred change to non-OCE, and then a change back will convince the radio to set itself correctly.

if this doesn't work, then the radio is faulty. It is not storing its settings properly. Get it exchanged.

I gave this a go today and it worked, it now scans in multiples of 9 instead of 10. My local dealer told me that this wasn't possible and another local M3 owner had the same problem.

Also how do you change the AF from manual to auto? Mine didn't seem to want to change.

Thanks

I live in Canada. I did the following because my radio was tuning at 9KHz for AM. when i checked the settings in the service mode it said no area. so i changed it. I had a CANADA setting. I changed it to that and its working now. BUT i have major static. not very clear but listenable.

Thanks everyone for this post

BM53 andAM Tuning - Thank you KiwiJochen!
 
FollowedKiwiJochen steps for post 9/01 and was able to change the country to USA.

After years of suffering with no AM radio I am in business.
Thank you!
