Wonder if a proxy alignment is worth a go before changing the key slot?

 

The odometer is flashing to indicate a 'CanBus' error. When the car is first started the circuits are all tested to ensure that the 'computer' that carries signals to the various devices is within tolerance. The way it signals a failed check is the flashing odometer.

The light on the Fob Slot is normal and indicates it is ready to accept the key. It stays live for a while after shutting down. But then the system enters a sleeping state to preserve the battery and the noise and lights stop.

 

That is exactly my problem. The light keeps blinking. Today I left the car 8 hours turned off and when I came I could still see it from the window. The odometer flashing i was able to recover by disconnecting the battery.

Looks like my car cannot go to sleep mode for some reason. I tried a proxy alignment but did not help.

Any other ideas?

 

Just ordered an used TEG reader. My mechanic suspects that there is some problem with it that prevents the car to fully go into sleep mode. I guess i need to do a proxy alignment after installing the new TEG. This problem is being quite anoying the car is consuming almost 1A after turning it off. Any ideas would be very welcome.

 

Anyone knows if I replace the TEG reader if I need to do some reprogramming? Can I do it with the MES? I thought the reprogramming only had to be done if I want to replace the keys...

 

Today I conducted more experiments while the TEG reader does not arrive and I think the problem might something more general:
- I removed the fuse F32 which is "Driver’s door branch point/passenger’s door branch point/ignition device ". Of course with this the light is turned off, but I still hear the noise from climate control which indicates the car is not yet in sleep mode.
- Removed F39 (Supply + battery for air conditioner, ceiling lights, volumetric alarm,EOBD system diagnostic socket) and connect back F32. Now I see again the light from the TEG reader but the noise from the climate control is gone.

with that looks like the problem is more general. Then in a desperate try, I removed F31 which is the body computer. Still the light on TEG reader and Climate Controler Noise was still there. That was puzzling, I was expecting the light to turn off as the body computer controls that CAN as far as I know

I will try to re-charge my battery as I dont have more ideas right now.... just to be sure it is not a battery issue..........:bored::bored::bored:

 

You know they don't go into sleep mode for about 8 minutes right? My AC whirrs away for several minutes after shut down if I sit in the car.

 

Unfortunately mine stays like that for the whole night

 

Changed the TEG reader but did not help :disappointed::grumpy::grumpy:

One question. When you changed TEG device in your car, did you have to do some programing or key can work without programing. I have problem with cold weather unlocking of my car and main problem is with TEG device.
Thank you

 

unfortunately nothing helped...I think there is some problem with the CAN bus or something... I love my Alfa, but I guess this time I will have to sell the car....a bit tired of problems lately...

 

Today I went to a Alfa Dealer but they said they need more time to find the problem. It is the first they saw this issue. However, I was analying again eLearn and if there were would be a bad grounding on the points C015 and C020, could that explaing the problem? Does anyone every seen those ground points? From the picture I cannot see it very clearly.

All replies would be very very welcome

I am really suspecting about those grounds. it is the only thing apart from the CAN bus I can see it is common to all modules where I see problems.

The car just came from the garage and it is fixed....The car required a new body computer which costed me 650€

Hope it will help someone in the future
