Just had a letter from BMW saying mine needs to go in

message sent kkx5

would the problem be that the chain has stretched inside the transfer box, causing the chain to jump the cogs and that is the noise and jerky feeling at low speed/pulling off and when on full lock?

Is the cable that i need to pull off connected to the actuator?

Thanks again for your help

ah I see can i ask where its located, i appreciate the help

so what am i looking for when its unplugged?

Sorry as new to this my first BMW auto

Mine dont fold on lock, so do all have the motors in them and they just need to be coded to get them to work?

what is it, where is it, and what will happen if I disconnect it?
Will it mess anything up if I unplug it?

Is there any way I can identify if its the transfer box before spending lots of cash?

2010 f25 2ltr diesel auto

All tyres and wheels the same size just different makes on front to the back ones

been getting a noise from front end that sounds like a cv joint knocking at low speed, on full lock, or just pulling away. but after reading some threads I decided to check what tyres I have on Fronts- Dunlop sp sport maxx 225/60/R17 star rated run flat Rear Pirelli P7 cinturato 225/60/R17 star rate...

lol its a bitch of a job

The link dont work for me but i did a search and they are the same type rivets used.
