Diagnostic Trouble Codes 18152 / P1744 - 5 Spd. Automatic Transmission 01V





1) If the selector lever in position D is shifted into the tiptronic gate, the shift procedure is recognized by the tiptronic switch -F189- and is transmitted to the Transmission Control Module (TCM).
2) The Tiptronic Switch -F189- also functions as the switch which recognizes the up and down switch. It is installed in the conductor strip in the symbol insert, this means that the symbol insert must be replaced if the Tiptronic Switch -F189- is faulty.
3) The Tiptronic Switch -F189- receives its tiptronic gate recognition information or tiptronic up-and downshift information via the large magnet which is mounted on the lateral gate cover of the gate cover. If the switch has become detached, the gate cover must be replaced.
4) Pay attention to which hydraulic control the transmission has when selecting measuring value block.

Note about DTC 18152 / P1744:

^ A malfunction is displayed when the tiptronic recognition is recognized, even though the selector lever is not in the tiptronic gate.
^ This malfunction can only be indicated for vehicles with tiptronic shift operation.
