K12 Radio code again

[Kowalski]

Hi

Can anyone help me out with a radio code for a 54 plate diesel SE?

Model Nissan MM CD-J

Part Number 7642347318

Serial Number BP234746085412


It also has a piece of card under some antistatic tape that says HP-3123

I tried 3123 and it now says wait 1H

Its been off for about 3 months and the first time I did get three attempts.


Thanks in advance.

Try 2121 or 0121 .

That was quick mate, thanks for that I'll give them a try. Any way to bypass the wait 1h?
I removed the battery for 10 minutes before now and it still said wait when I reconnected it.
