Hi Guys
Got my car today. 335 i Xdrive, coupe, sports package, paddles etc.great. it had 2 miles on it. drove it for 120 miles in the highway AMAZING ! I think though there is a problem : when I start going from a stand still (automatic transmission ) there is a bump i feel and the gear shifts is just not right/smooth. it only happens on very low speed just at the very beginning, not when I am on higher speeds. again, it feels like the transmission gets stuck and than continues, it does not feel normal to me ,Any suggestions/ experience with this ?
Thanks

SUBJECT
E9x, E6x with 6HP19TU - Jolt and Delay when Pulling Away
MODEL
E90, E92, E93 (335i) with N54 and 6HP19TU from 03/07
E60, E61 (535i) with N54 and 6HP19TU from 03/07
E60 (528i) with N52K and 6HP19TU from 03/07
SITUATION
The customer may complain of a delayed engagement and a harsh jolt when accelerating from a stop.
The situation occurs only during the engine warm-up phase (cold engine), and cannot be reproduced in the
Sport Mode.
CAUSE
EGS software (unfavorable NIC – Neutral Idle Control) calibration
SOLUTION
On a customer complaint basis only, check the vehicle's integration level.
If the integration level is:
On E9x vehicles - E89x-07-06-520 or lower
On E6x N54 vehicles - E060-07-09-530 or lower
On E60 N52K vehicles – E060-08-03-550 or lower
Reprogram and recode the complete vehicle with a current Progman version (target levels are E89x-07-
09-518; E060-08-03-510; and E060-08-09-520, respectively, for E9x, E6x N54 and E6x N52K vehicles).
Important Note:
The NIC (Neutral Idle Control) feature disengages the torque converter from the transmission when the
vehicle is stationary in the Drive position; the service brakes are applied; and the engine is still in the warm-
up phase. The NIC function eliminates engine load when vehicle is stopped, reducing fuel consumption.
Although the EGS software changes (as listed above) are improving transmission comfort feel while
still providing the benefits of the NIC feature, they still may not be acceptable for the most discriminating
customers.
In such a case, on a customer complaint basis only, deactivate the NIC function by performing the
"Converter lockup clutch" retrofit, using the current Progman/ISTA P version.

Give it some time, it might smooth out after a while.

Sounds like you know that for sure, even when you haven't even seen the car before.

Wow
I gues I need to print this out, schedule appointment with the service department and get there asap.
BTW : it happened to me when I had been driving for an hour, the engine temp was ~ 250, so I guess the warming-up phase had already been passed
yet, I still had this problem.
Is there any concern for damage ?
Thanks

250F? Shit. I've never seen it that high. 235F is the highest and I live in Texas.

[nbbimmer]

I just got a new e90 LCI 335xi 6AT too. It's one week old. The first day I also felt a clunk from the transmission, but it disappeared the next day. I haven't noticed it since (I drive it daily to work and back, but only 100 km total so far)

[blackpepper]

Got back from another ride. this time I kept the car on the sport mode - (automatic), the noise/bump were just gone. the car was smooth and did not make a sound.

My car hits that very often...it's totally normal.

It doesn't happen in sport mode.

An update
This problem has gone. dont know how and why, i guess someone else mentioned his car did the same, and that the problem was gone after 24 hours, same thing here. test driven it on cold engine, nothing's wrong, as smooth as butter. i wonder if this is just the nature of this car,system "learning" process ?
Anyway, thanks for your advice. I now can say I am a new owner of a BMW and I am LOVING IT !!!

I had a similar, but slightly different, experience with my now two-week old 335i X-Drive AT. The first day, taking off from a standstill was smooth, but the 1-2 shift seemed excessively abrupt, and I felt it was something I'd have to have the dealer look at. A few days later, it's smoothed out completely. Maybe there indeed is some initial break-in/adaptation occurring with brand-new automatic transmissions.

That's what I think happened to me.

Looks like from the OP's update, it turns out you are wrong instead. Don't be so sure next time, buddy.
