BMW 740Li xDrive stuttering during acceleration issue requiring transfer case replacement on BMW 740Li xDrive

Some BMW 740Li xDrive owners report experiencing stuttering during acceleration, which may be linked to several underlying issues. These problems can stem from a malfunctioning transfer case or a worn-out clutch pack, leading to a lack of power when accelerating. In some cases, owners may need to visit BMW for a CCP replacement, which involves replacing injectors, tubes, MAFs, and other critical components. A complete XDrive failure could also occur, requiring a costly transfer case and differential rebuild or replacement. Ignoring control display warnings related to the xDrive system can exacerbate the situation, although cycling the ignition may reactivate the VTG system. Additionally, jerky acceleration might be caused by worn fixing bolt holes in the rubber flex disc, while fuel delivery issues or damaged CV joints could result in vibrations during acceleration. Some owners have identified torque converter problems, which can be expensive to repair, although changing transmission fluid may offer a more economical solution. Understanding the operation of BMW's xDrive system, particularly the absence of a center differential, can help diagnose potential windup issues caused by differing front and rear axle speeds. It is recommended that owners have their vehicles inspected by a qualified mechanic or BMW specialist to accurately diagnose the stuttering issue and determine if a transfer case replacement is necessary.
