I am the OP on this thread.BMW "opened a case" on my '25 760i in February for my rough idle complaint.My '23 was doing the same thing when I traded for the '25.BMW spent about 7k in warranty repairs chasing the problem.They cleaned the fuel induction system for carbon build up.After that work was completed, they got a fault code on the valvetronic system.They ended up replacing the valvetronic motor for bank 1.It was idling fine when returned to me.I have other posts about taking the opportunity to return the car 7 months early immediately after service on a no cost buy back.They have already sold it.Somebody got a heck of a car,assuming the problem doesn't return.I loved that car but with the idle problem and looming LCI interior design issues,I decided to make a move.It kind of made me feel a little sick!I had the first allocation for an LCI order but couldn't pull the trigger without seeing the car first.I'm now in a '26 S580 on a Mercedes special 13 month lease and really enjoying it.It's a different drive.I'll have multiple options moving forward after first seeing the 7 and S Class LCI versions.BMW can build a solid 6 cylinder but have struggled at times with the the 8's.They are fully aware of these idle problems even though no TSB's have been issued.Stick to your guns and get your issue resolved.A 130k car shouldn't shake when idling.
