Need help

2019 g05

Just had the transfer case looked at by the BMW dealer I bought my car from. Its been bad from the start, so they have done it under warranty, got it back today, and all is fine on the 50-mile drive home. But now it's raining, and it jumps when pulling away.
They changed the oil and stated there was no damage?

Is this normal?

Did the dealer do a software update as part of the transfer case replacement? If so, maybe some settings were reset, including the drivetrain learning.

Take it out for a few drives and see how it performs/behaves after several drives.

SIB 27 02 20 states that after the transfer case fluid change, there is a 125 mile run-in period: “The shuddering should diminish during this run-in period before completely smoothing out.”

Might just need to drive more before it goes away.

I dont know if software was done, they only changed the oil not the case. I have contacted them, will see what they say. They didnt tell ne to drive some distance to sort it.

Thanks, others have said that as well, its a shame they didnt tell me before I drove off. Hopefully the miles will fix it. I have contacted them and Im going back next Friday when another part arrives so by then it will have a few hundred miles on.

Gotcha. I misread your post and thought they replaced your TC.

There’s a class action lawsuit against BMW on these if you weren’t aware of it already. They know they have a major issue, same with front differentials. Just sold my 2021 X5 M50 yesterday after my front differential failed at just 36k miles in November. $11k job. Out of warranty.

Done with the brand for good.
