To Code this transmission, make sure Ignition is ON, but Engine is NOT running.
When replacing this module use the coding from the original unit or the repair manual coding charts.

Adaptation

This article applies to the Audi A4 (2008-2015). There is quite a bit of difference between the Manual, Tiptronic, Multitronic CVT, and S-Tronic DSG transmissions, much more so than just 6-speeds versus 8, or unlimited for the CVT.

  • The Audi A4 (B7) 2.0 TDI Multitronic has a Inline 4, Diesel engine with 1968 cm3 / 120.1 cu-in capacity. How many horsepower (hp) does a 2004 Audi A4 (B7) 2.0 TDI Multitronic have? The 2004 Audi A4 (B7) 2.0 TDI Multitronic has 140 PS / 138 bhp / 103 kW. How much does a Audi A4 (B7) 2.0 TDI Multitronic weighs? The Audi A4 (B7) 2.0 TDI.
  • The Audi A4 is a line of compact executive cars produced since 1994 by the German car manufacturer Audi, a subsidiary of the Volkswagen Group. The A4 has been built in five generations and is based on the Volkswagen Group B platform. The first generation A4 succeeded the Audi 80. The automaker's internal numbering treats the A4 as a.

Special Procedures

Defined Test Drive

Prerequisites:

  • Ignition ON and Engine ON.
  • No Fault Codes stored.
  • Transmission Oil Temperature must be between 60 °C and 90 °C.
    • If the procedure does not succeed in the first try, make sure the temperature is above 80 °C.
  • All driving and braking has to be done in partial load, avoid full throttle/braking!
  • Normally the adaptation needs to be carried out when:
    • Transmission Control Module has been recoded
    • Input Shaft has been replaced
    • Hydraulic Unit has been replaced
    • Transmission Control Module has been replaced
    • Transmission has been replaced

  • Move the selector lever in position D and drive with partial load 20 m / 70 ft forward, then brake to standstill.
  • Hold the brake for 10 seconds.
  • Move the selector lever in position R and drive with partial load 20 m / 70 ft reverse, then brake to standstill.
  • Hold the brake for 10 seconds.

The procedure needs to be repeated at least 5 times and can be repeated up to 10 times until the measuring values show ADP OK.

[Close Controller, Go Back - 06]

Replacement

  • Run and save a complete Auto-Scan and save it prior to module removal. See the Online Manual Auto-Scan.
  • Code the module with the Coding from the original module found in the Auto-Scan.
  • Complete the Adaptation as shown above followed by the Defined Test Drive.


Note: The (4F) chassis Audi A6 uses Component Protection and will result in the 18109/P1701- Transmission Control Unit: Locked fault after module replacement. The transmission will have limited functions prior to the dealer SVM process required for unlocking Component Protection


Special Notes

Audi A4 Multitronic
  • The CVT TCM must be ordered by VIN due to the specific programming related to the engine configuration, market/country configuration and 6 or 7 plate clutch system. The Component field will display some of the mentioned information when scanning it with VCDS. Installing the incorrect TCM will have undesirable results.
  • If the Adaptation values are not stored to the TCM in the NAR (North American Region) Audi A4, A4 Cabrio and A6 models ranging from 2002 through 2008 see TSB: 37-08-20 (2015849). This TSB explains some of the conditions that may cause an unsuccessful adaptation drive.

Audi A4 Multitronic Review


All of the following procedures must be performed in order, WITHOUT shutting off the ignition or exiting out of the ABS controller.

Login

Note #1: After Login has been carried out you need to recode the control module.
Note #2: Special Login 09399 is used for BFB Engine with 1LT Brakes and Multitronic.
Note #2.5: Special Login 07499 is used for 6-Cylinder Diesel Engine with 1LG Brakes and Multitronic.
Note #3: The Production Codes (PR-Code) such as 1LX can be found on a Sticker near the Spare Tire Well and/or the 1st Page of the Service Manual. Click here to see an Example of a Sticker.

  • 0?xxx: Chassis
    • 9 = Audi A4
  • 0x?xx: Brakes
    • 2 = Brembo 17' (PR-1LJ)
    • 3 = FN3 16' (PR-1LT/1LF)
    • 4 = HP2 16' (PR-1LX)
    • 4 = FNR 16' (PR-1LA/1LG)
    • 5 = FN3 15' (PR-1LB/1LE)
    • 6 = C54 (PR-1LZ)
  • 0xx?x: Engine

    • 9 = 6/8 Cyl. Gasoline
  • 0xxx?: Transmission
    • 5 = Manual
    • 7 = Automatic (5HP19, 5HP24, AG4, AG5)
    • 9 = Multitronic (01J, CVT)

Coding

Audi A4 Multitronic Gearbox

Note #1: Coding is accepted after a specific login has been carried out.
Note #2: After successful coding the steering angle sensor basic setting needs to be carried out within the same diagnostic session.
Note #3: Special Coding 04499 is used for BFB Engine with 1LT Brakes and Multitronic.
Note #4: The Production Codes (PR-Code) such as 1LX can be found on a Sticker near the Spare Tire Well and/or the 1st Page of the Service Manual. Click here to see an Example of a Sticker.
Note #5: In some cases, you will need to enter a non-zero WorkShop Code, such as 12345.

  • 0?xxx: Chassis
    • 4 = Audi A4
  • 0x?xx: Brakes
    • 1 = C54 (PR-1LZ)
    • 2 = FN3 15' (PR-1LB/1LE)
    • 3 = HP2 16' (PR-1LX)
    • 3 = FNR 16' (PR-1LA/1LG)
    • 4 = FN3 16' (PR-1LT/1LF)
    • 5 = Brembo 17' (PR-1LJ)
  • 0xx?x: Engine

    • 7 = 4/5 Cyl. Gasoline
    • 9 = 6/8 Cyl. Gasoline
  • 0xxx?: Transmission
    • 5 = Manual
    • 7 = Automatic (5HP19, 5HP24, AG4, AG5)
    • 9 = Multitronic (01J, CVT)

Basic Setting

Steering Angle Sensor (G85) Calibration

Before starting the procedure turn the steering wheel at least 30 ° left and back straight ahead.

[Meas. Blocks - 08]
Group 005 Field 1 (Steering Angle Sensor -G85-)
Specification: 0.0 °
Tolerance (when straight): ±5.0 °
[Done, Go Back]

[Login - 11]
Enter 40168
[Do It!]

[Basic Settings - 04]
Group 001
[Go!]
[Done, Go Back]

[Fault Codes - 02]
All fault codes should have disappeared.
[Done, Go Back]


Special Notes

  • Some of the Bosch 5.7 modules will not show live Steering Angle Sensor (G85) readings after the Login and Coding are performed. If this is the case -2.5 ° may be stuck in Measuring Block 005 and will not change when the wheel is turned. Make the wheels as straight as possible and continue with the Steering Angle Sensor (G85) Calibration.
  • After doing the G85 Calibration, you may get a 01486 - System Function Test Active, this is normal. Please see 01486.
