designates changes to this revision
SUBJECT
A Slight Bump is Felt Shortly after the Vehicle Comes to a Stop
MODEL

E90, E91 All with the GA6HP19Z transmission produced up to 09/2006
SITUATION
A slight one-time bump is felt shortly after the vehicle comes to a stop.
CAUSE
This is due to the design concept of "NIC", or Neutral Idle Control. This gearbox feature uncouples the torque converter whenever the vehicle is stationary, gearbox oil temperature is between 20C and 120C, and the brakes are applied. By disconnecting the torque converter the load on the engine is reduced to a minimum. Please explain this feature and its operation to the customer.
CORRECTION
For the E85, revised EGS software is available with Progman 23.0 or higher.
For the E90, E91 revised EGS software is expected in a future release of Progman. Until that time, on a customer complaint basis only, this feature can be deactivated as described in the procedure below.
PROCEDURE
E85 On a customer complaint basis only, reprogram the EGS module with Progman 23.0 or higher. It is not possible to deactivate this feature using the retrofit option on the E85.
E90, E91 - On a customer complaint basis only, perform the Retrofit - "Converter lockup clutch" using Progman 23.0 (Target Data status: E89x-06-09-520) or higher. Follow the "Retrofit" procedures as outlined in SI B09 05 01.
