[Harri]

Hello,

Here´s a problem:

My friend has a 1994 740, the automatic A/C panel (with restwarm) and it has got pixelproblem (pixelfehler)with "old spec" panel with two LCD-panels.

So i read your very informative forum and found out, that facelift A/C panel should fit directly to the car.

I bought new facelift panel from the ebay (with restwarm), but when we fitted it, the A/C didn´t work correctly.

No problem i said, just code it at the BMW-dealer and it should work.
...well it didn´t. They couldn´t find the new panel with their diagnostics system at the BMW-dealer!!!

Could someone give information, what could be wrong. We have taken the battery cable off few times, but nothing helps.


Old panel partnumber:

64188369781

The new panel partnumber: (which doesn´t work correctly)

64118377581

BMW dealer recomended panel 64116901307, which should work.

Please give me some help, Sie können auch im deutsch anworten...
