MODEL
E60, E61, E63, E64 with 6HP19TU or 6HP26TU transmission produced from 06/09/08 up to 11/03/08
SITUATION
The customer complains that after the engine has started or during parking maneuvers, the drive position D or reverse R cannot be engaged using the GWS (Gear Selector Switch).
One or a combination of the following faults may be stored in the GWS shifter:
^ A828 Function indicator faulty;

^ A834 Hall sensor, single fault;
^ A835 Hall sensor, dual fault;
^ A83A Invalid lever position;
^ A83D Processor faulty;
^ A83E P magnet actuation faulty.
CORRECTION
Using the ISID, check the part number of the GWS via path:
^ Control unit tree;
^ GWS;
^ Call up ECU functions;
^ Identification (BMW Part Number).
If the fitted GWS Part Number is:
^ 61 31 9 174 981; or
^ 61 31 9 174 980; or
^ 61 31 9 189 638; or
^ 61 31 9 189 640
Then reprogram the complete vehicle with the current version of ISTA/P (the improved GWS software was introduced as of ISTA/P 2.32.1).
Note:
On vehicles produced after 11/03/08 (with GWS shifter P/N 61 31 9 294 091 or P/N 61 31 9 204 093), the shifter should be replaced with a new part (same part number), should the above-listed complaint and fault codes be encountered.
