Quelltext der Seite No engine start possible - code needed

= Your vehicle suddenly asks for a code after replacing the radio and will not start the engine? =
Possible reasons for a sudden code query include insufficient voltage or disconnection of the battery.<br />
<br />
== Extract from the manual ==
<br /><br />
''After three incorrect code entries or after three attempts to start the car without entering a code, an alarm sounds for 30 seconds on vehicles with an alarm system.''<br /><br />
'''''Emergency disarming:'''''<br />
<br />

''If you have forgotten the code, follow the procedure below:''

''1. disconnect battery and reconnect after approx. 2 minutes, alarm sounds for vehicles with alarm system''<br />

''2. switch the ignition key to position 1: The display shows a time display that runs backwards for ten minutes''<br />

''3. start the engine after ten minutes''
<br />
<br />
== Available code ==
There is a code that has probably made it possible for some to start again immediately:<br /><br />

<big>'''0000'''</big><br />
<big>'''1234'''</big><br />
<big>'''2767'''</big><br /><br />
== Further option ==
Temporarily disconnecting and reconnecting the radio can also solve the problem.<br />
Some users report that disconnecting the USB connection in the app (under general settings) also bypasses the query.
