New member here, Rennlister and 9Y0 Cayenne owner. Wondering if the MLB Q8 owners are experiencing driveline judder or shudder around 60mph / 2,000rpm / 6th gear with the ZF8HP transmission.
I think the Q8 and Cayenne share drivetrains. Specifically in question is the so-called "hang-on" all wheel drive device. It is in the place where a traditional transfer case is located, but it is a wet multiplate controllable torque coupling. It is not a classical chain-driven sprocket type transfer case. Is it produced by Magna who calls it the "Flex4".
A number of Cayenne owners are reporting judder or shudder in the operating conditions noted above. This happens with/without throttle applied, with/without brake application and in Normal or Sport+ modes. We have not yet affirmatively identified the root cause. If we can pinpoint the root cause, and repeatedly recreate the problem, the dealers will have less to push back on.
Any comments will be appreciated on driveline vibrations, rumbles, shudders, judders, etc.
p.s. I looked through several pages of threads and didn't see one related to the question.
