2011 X5 Transmission Light

Hi,

I'm new to the site and my 2011 X5 40d E70 is my first BMW (possible my last). The transmission light comes on. I've had it in the garage and the fault code is 4E9B. The garage have advised that the car needs to go to a gearbox specialist. Any advice would be greatly appreciated ☺️

    Morning Christine

    Welcome to the Forum

    I would be concerned about your garage as the only time I have seen that code was on an X5 with an incorrectly fitted battery (IBS not connected)? First I would point out that I am not a garage just an old engineer with an insatiable need to know 😅 I also have a fully up to-date BMW Diagnostic program and have worked on my own X5's since 2002. Google the register of BMW Specialists you should find one close by

    I would start with the battery, get the Voltage checked at the Charging points under the bonnet. Engine off it should show 12.5v minimum with the engine running 14.5v min. Also check the battery connections in the boot make sure the IBS (small lead) is connected

    Hope this helps

    Thank you for replying Dave. I have watched a few YouTube clips and Googled everything I can. The battery is something that came up a few times. I spoke to the garage about this and it is going in on Tuesday so they can check the battery before I start spending stupid money. I will let you know how I get on ☺️

    Hi Christine

    BMW's are well known for being sensitive to Battery voltage I have seen quite a few with either a parasitic discharge or discharged battery. The discharged battery will still start the car but diverts all energy to the start triggering all sorts of spurious warnings. For your information if the battery is charged on the car it should only be charged from the charge points under the bonnet. At the battery your car has an IBS lead (Intelligent Battery System) which lets the cars system know if it is charging or not. I have seen a few BMW's that have batteries changed and the lead has not been reconnected

    Transmissions are pretty robust but just like the Engine do need servicing

    Hope you get it sorted

    Dave
