Jmol is on a distinguished road
ISTA no communication to modules (egs,...)

Hi all,

New to the forum here, recently bought an bmw e53 4.8is from 2004. I'm working on the maintenance (zero status) and wanted to do a transmission oil change including the mechatronics seals.

To replace those i need to be able to readout the oil temp. in the gearbox.
I have connected the to ista and found many fault code related to "no communication"

I have checked the obd connection for a 12V supply on pin 16. which is present.

Can you guys please help what to check next?
