door actuator

[Bmwforachange]

Hi All,

I've tried looking at the existing threads but can't see an answer to my problem.

I was having issues with the drivers door not opening. I replaced the bowden cable and fitted a new actuator. While this has solved the mechanical failure the door no longer opens on the key fob and central locking doesnt work. With the new actuator fitted the door open light is lit on the dash.
If I disconnect the connector and fit it to my old actuator while holding it but not fitted I can then flip the latch, the light goes out and I can operate the central locking. This leads me to believe that the new actuator needs to be coded in some way.

Does anyone have any ideas? I've had hours on this one and it's got me stumped.

Thank you.

No coding needed. Did you fit an OEM actuator or an aftermarket one?

I fitted an aftermarket one (Febi). This didnt operate the central locking. I thought the new part was faulty, returned it and ordered another aftermarket from another source. With the same result.

So I'm now thinking, only OEM actuators work with the central locking.....
I've fitted it incorrectly, not followed a procedure etc.....

It's just strange that the old mechanically broken actuator still operates the central locking if plugged in.

Thanks for the reply. appreciated.
