Hi there, I have owned a Astra G 1.6 2004 since December 2020 and had many faults.
The first being the ecu went bad and was sent off for rebuilding.
Now, the current issues;
1. The car vibrates a fair bit at idle and has recently stalled upon start up and also stalled coming to a stop at lights it then struggled to start again.
2. I've just plugged in my obd2 reader and have a U2106 'manufacture control' error. Dashboard stays on after removing keys. (both times a month apart, before and after new ecu, I believe was caused by ucb cigerette port, as I had dashcam and phone charging when I turned off engine, and dash stayed on. To turn of dash I had to remove USB adapter, and when I start the car I'd have an engine light. Clearing engine light meant it didn't come in again until the same situation occurred.
3. I've used a Bluetooth obd2 and torque reader and have these codes
C3f18 - chassis
Po216 - Power train
P1614 - power train
P34e1 - power train
P3419 - power train
U2106 - network
U2106 was red, the others were grey within the torque app.
4. I can hear water dripping behind dashboard, and it's louder when revving, only heard it for a few minutes on startup.
5. On the torque app it says "fuel system status: closed loop using 1 02 sensor 'feedback fault')
I do hope someone has a little insight.
Kind regards,
Chris.
