Hi everyone.
Appreciate if someone could tell me where the ECU module is located in these cars.

Thanks in anticipation

Open the hood.
Take off the seal between the engine and the battery cover.
Now remove the plastic piece over the battery (together with the battery cover) and brakes fluid reservoir.
You will see a black box (i have it on the driver side, LHD car) sealed by a few torx screws.
Unscrew them (you don't need to remove the wipers, just use an angled wrench), pull the ECU cover.
ET VOILA'.
