To be honest, I don't think ISTA will be very helpful to you. When it comes to software, an E39 is most compatible with INPA.

If you're looking for software like INPA, you can find it by searching for "Mike's Easy BMW Tools" online.

For how long did you hold down the shift and brake buttons at the same time? The auxiliary fans may not activate at full power for ten to twenty seconds.
