Hi there
I need some help please.


I have a BMW e53 x5 diesel - automatic.


A few moths ago i had the ABS, Warning and 4x4 light come on my dashboard.
Also i noticed that when i was driving sometmes i would get a 'jolt' which felt like it was coming from the rear of the car, almost like someone has hit you from behind type of thing.


I checked online and replaced the actuator motor gears as they always seem to get damaged.


This made no sifference at all. So i then replaced the actuator motor that i purchased from ebay.


When i checked the old actuator motor i found that the brushes were worn down and there was not contact to make the motor work.


Now, the issue that i have is that the ABS and warning lights sometimes are not illuminated and the drive seems a lot better.
The lights never come on when i am driving but always when i stop and switch off the car and then start it again, there is a good chance of the lights coming back on again.


The 4x4 light stays on all the time.... the reason for this is that i need a new steering wheel angle sensor. So i am not really worried about that at this stage.


Also, I have changed the transfer case oil a few months back with genuine BMW transfer case oil.




Error codes
I used a handheld bluetooth scanner and i got the 4f7a error code


Can anyne help me with this issue? do i need a new actuator motor or could it be something else?


Thank you for your help.
