Opel Astra H 1.9 starting problems

[Rebound]

hi all!
I don't know if it is a common problem but I can't seem to get to****...
Car: Opel Astra H 1.9 2004
The car does not always start:
you have to turn 2-10 times the key in the framework for starting the starter motor, and then leave.
Once a match , turn the key without estarla the drive part;
if, instead, it extracts the key starts the problem...
I disassembled the engine ecu as the diagnosis gave me intermittent signal can bus with ECM and I have found traces of water in the ecu, cleaned, and cleaned the welds, the problem remains...
to someone ? happened to you?
I thank you in advance

I would check the ignition switch of the key..

[carlo abarth]

in diagnosis that gives you the????

[Rebound]

can bus signal intermittent with ECM...

[Alessio93]

I would try to reset it and reprogram the codes of the 2 keys

[Rebound]

the machine brings the encoding on the light switch behind the steering wheel...prover? to encrypt another key...

[Rebound]

replaced the ecu the problem start ? resolved...
now it's for? the calibration of the steering angle...obviously in the dismantling of the cim is sar? moved the cap that contains the spiral cable...
better to try to calibrate it manually, or you can try with the diagnosis?

[jolidj]

if you have the tech2 you put in less if no manually. I don't know if other diagnoses.

[Rebound]

manually means to find the point of the original cim right?

[Rebound]

you can't calibrate...
the light remains on, but it all works... does not accept the car pass for calibration, with a tech2;
and once disassembled, it is centered...
advice?
