Installation and preparation
The IMMO OFF Plug & Play version needs no programming or immobiliser adaptation. The ECU runs without errors after fitting. If you prefer a clone of the data from your own ECU, we will make it on request once you send the ECU or its files.

An ECU fault may be indicated by, among others:
- no diagnostic communication with the ECU
