Technical Enable to connect to ECU :'( :'( :'(

[ahmed87]

This car is driving me crazy :bang:

I have recently disconnected the battery, and since, Blue&Me is not working and the odometer is blinking.

I have downloaded and registred MultiEcuScan, and bough a Bluetooth elm327 and a Wifi one to do a proxy alignment.

I'm not able to connect to ECU, i keep receiving ecu connection failed, i'm not even able to connect to the car ! is there a fuse to check or any tip please ?

Thank you so much for helping
