Hiya guys ive searched and searched and only come up with what ive done. Basically my issue is ive had e53 3LD sport 2005. Been sweet as for last few months the odd three lights come up DSC 4x4.abs But turn engine off and Bk on gone for a few more days now. Everytime after i drove over a cobbled roundabout. Lost drive stopes turened engine off Bk on drove but errors.now I drive 4x4 abs and a red light pops up left side of abs. Car feels like its holding Bk only rear wheel drive chamged tyres to new cost wnough. From what ive read it all points to the transmition actualtor. Sooo.... bought new cog fitted same issue. Now im thinking the actual actuator motor is gone. As diagnostics showing tramition somit. Im litarlly pulling what little hair I have left out. As its only real wheel drive. Not sure how to.add pics

We need the actual error. It could be the steering angle sensor that has an issue. That is known to bring the trifecta (three warning lights) on rather than it being a transmission issue.

If it is showing a transmission error code, then what code? Need the error code number and error text (description) if you have it.

Ideally all four tyres should be of the same make and tread depth - especially if the sizes are different on each axle. Use of non-‘*’ marked tyres is known to cause issues, though not so much in the E53.

And

Update Ive been told to remove actuator and try move the spline protruding out-of the transfer box I can only move it backwards which feels like its on a spring and springs back anticlockwise. To a stop. The car is only rear wheel drive at the moment. I'm afraid of doing more damage. If I keep driving it. Next step is drain oil from transfer box and see what colour it is. Maby new transfer box is needed. When car is up off ground only front wheels spin freely the rears won't move Evan in neutral. And the front prop/ drive shaft won't turn but front wheels spin freely. I'm stumped as to what to do.
