Possible 540iA

That is instrument cluster self test... to reveal if the instrument cluster belongs to the car by displaying the VIN number.

Stomp test is engine diagnostic... you have to try a couple of times to figure it out... I also had difficulty to get it to do that too. Gotta turn ignition off after every time you attempt to do so.

Thanks for the info.....So I tried again (on my 525i). Turned the ignition on, immediately stomped 5 times rapidly and firmly and I got the 1444 code. Now I know how it works. I am going to stomp test the 540i now and see what it has to say. You are correct, it took me several times to get it to work.
