Hi there.

I have searched and I can't find an OBD2 app that will monitor auto transmission fluid temps while driving/towing with my E53 ('05 3.0)

INPA loaded on a laptop can do it thru an OBD2 connection, so I believe it's possible.

I have tried OBDFusion basic version, and they don't offer enhanced diagnostics for BMWs. I have also tried Car Scanner Pro which seems to work for an E70 X5 (per below), but does not seem to work for mine...

Has anybody found an app that works with the E53?

Thanks
