Trying to figure out my transmission code when I run ista+ it gives me the code EGS_0x32 if I change the transmission control module with this fix that

Morning Nick

Welcome to the Forum

ISTA should give you a Test Plan ? just changing the EGS may not be the fix (sadly most Garages change parts to quickly at customer cost) I would first use a good Electrical contact cleaner on the EGS and Loom connector and test continuity on the loom. If the loom and its connections are good check the Internet for EGS tests

If after checking everything out it still points to the EGS then there are some things to consider. Early "E" series cars the EGS had no internal ISN (Internal Security Number) Later "E" series cars the EGS with ISN are Grouped with the DME/DDE and CAS so if changing the EGS you will need a Matching DME/DDE and CAS plus polish your skills with ISTA P

Hope this helps more than hinders
