BMW 140I F21 – BMW ISTA Diagnostics

Last week we had a call from a local Mercedes specialist in Suffolk that had a BMW 140I in with a failed steering motor due to water damage. Their customer had supplied them with a “new” steering motor we had been tasked with coding and programming this EPS unit to the vehicle. The basic setup can only be performed with advance diagnostics including BMW ISTA+ to setup and have a fully working, fault free and calibrated installation.

On arrival we ran a full vehicle test with BMW ISTA+ that showed the EPS was indeed at fault so we proceeded to swap the EPS unit and programme BUT following all normal procedures to code and programme the EPS this failed due to no communication and a Flexray issue. we suspect this “new” EPS motor was also damaged. We tested the power supply to the motor and the 3V flexray signal everything was working as expected.

We advised to get a working EPS unit install so as we are able to programme and code.
