Engine Control Module -J623-: Notes
WARNING: This page is about a different car, the 2015 Audi Q7, 2014 Audi Q7, and 2013 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Some engine control modules are not equipped with a protective housing. The removal and installation of the protective housing depends on the engine and transmission combination.
The Engine Control Module (ECM) -1- is bolted to a protective housing -5-. To make removing the shear bolts -4- for the retaining tabs -2- more difficult, the threads are coated with locking compound.
To disconnect the connectors from the ECM (for example to connect the test box or to replace the ECM), the protective housing must be removed.
