Volkswagen launched its first DSG (Direct Shift Gearbox) in 2003 named the DQ250

Volkswagen VCDS Auto-Scan

Auto-Scan to See Codes

The DQ250 transmission is commonly referred to as the 02E which is the first three digits of all the transmissions part numbers. The 02E is a transversely oriented front-engine, front-wheel-drive and or Haldex Traction-based four-wheel-drive transmission with 6 gear ratios, dual wet clutch and integrated Mechatronics. The 02E also has a external filter and integrated drain, filler & level check plug and is recommended to be service every 4 years or 60,000kms (which ever occurs first) please see you log book.

Mechatronics Resetting Procedure

During each DSG transmission service or Mechatronic change over it is recommended to carry out the basic setting procedure in the TCM by using a scan tool, we recommend Ross-Tech VCDS software.

Engine Adaptation

  1. Do a full Auto-Scan on the system and print out your scan report, then clear all codes.

  2. Go into 01-Engine and click 10-Adaptation.
  3. In channel enter 00 and click Read, accept/agree to the prompt.
  4. Then click Done, Go Back.
  5. Click 04-Basic Setting in the first group box enter 060 and click Go a successful throttle body sweep learn will show OK! when complete.
  6. Next in the same Group box enter 063 and click Go 10 Times should show up in one box hold foot on throttle pedal 100% untill a successful kick down learn will show OK!
  7. Click Done, Go Back on Adaption Screen and Engine Screen
    (Please Note: Some diesel engines will not allow adaptation to be clicked, there maybe a kick down basic setting but it may not work also. All diesels that allow the adaptation to be carried out will only allow the kick down basic settings be preformed.)

DSG Transmission Basic Settings

Before you start…

  • Fluid lever is Correct and no fluid leaks.

    VCDS Basic Setting Screen

  • Fluid Temperature 30…100 °C (86…210 °F), see Measuring Blocks, Group 019.
  • Selector Lever in P
  • Ignition ON
  • Engine ON (Idling) for one minute or more
  • Brake Pedal operated (hold for the whole procedure)
  • Throttle Pedal not operated
  1. Now click on 02-Auto Trans and click 04-Basic Settings.
  2. In the first Group box enter 061 and click GO!  (DSG Engaged Calibration)
    All the numbers should start to move and the transmission will start making noises, watch the top of the screen when finished should show ON!
    The the numbers will stop changing and the noises will stop also.
  3. In the same Group box enter 060 and click GO! (DSG Synch. Point. Measurement)
    All the numbers should start to move and the transmission will start making noises, watch the top of the screen when finished should show ON!
    The the numbers will stop changing and the noises will stop also.

  4. Next in the same Group box enter 067 and click GO! (DSG Wet Clutch Adaptation)
    This should show ON straight away but still click ON/OFF/NEXT.
    Some early versions of software dont have group 67 and will require group 062, this is not very common.
  5. Next in the same Group box enter 068 and click GO! (Reset Clutch Safety Function Values)
    This should show ON straight away but still click ON/OFF/NEXT.
  6. Next in the same Group box enter 065 and click GO! (Reset Pressure Adaptation Values)
    This should show ON straight away but still click ON/OFF/NEXT.
  7. Next in the same Group box enter 063 and click GO! (Reset Steering Wheel Paddle Installation Values)
    This should show ON straight away but still click ON/OFF/NEXT.
  8. Next in the same Group box enter 069 and click GO! (Reset ESP & Tip Cruise Control Installation Values)
    This should show ON straight away but still click ON/OFF/NEXT.
  9. Preform one last scan of the system.

Test Drive

With engine still running you can exit out and close VCDS and turn off your laptop computer, it is recommended to Drive in Tiptronic Mode from stand still up to 6th Gear, 3rd-6th gears need approximately  5 minutes of drive time in each gear.  For a good clutch calibration the engine speed window for all gears is 1200 – 3500 RPM. Perform one sharp braking followed by a full throttle acceleration (oil return check) while in Drive, Not Tiptronic Mode. Evaluate creep and starting-off points in both drive and reverse. Keep in mind if the required test drive cannot be performed in the recommended way or the necessary time, any remaining adaptations will be performed automatically during normal driving. Explain to your customer to drive normal and to to try to drive around any issues they may feel.

Direct Shift Gearbox Explained

Introduction…

The Multitronic variable automatic gearbox developed by Audi is commonly known as a CVT gearbox. A CVT transmission uses a chain drive which has a reduction ratio between the shortest and the longest ratio and can be controlled steplessly by means of a so-called “variator”. This means there is only one constant gear with a belt running over a cone shaped input & output gear set, which allows the engine to run at optimal RPMs, for best emissions, mileage performance and a smooth, shiftless ride.

Vehicle List (6 Speed Electronic Shift)

  • AUDI A4 2001-2007 (01J) Multitronic CVT Transmission (gearbox code DZN)
  • AUDI A6 2003-2007 (01J) Multitronic CVT Transmission (gearbox code DZN)

Servicing the Transmission…

As with all transmissions preventative maintenance is key to the reliability of your vehicle. Continuously Variable Transmissions (CVT) are always under constant load and pressure regulation and metal to metal friction. CVT’s have a high risk of oil foaming which raises the risk of poor lubrication and increased wear to internal lubricated parts. Changing the fluid will give better stability, lower the risk of foaming, increase metal to metal friction protection and prevent overall transmission wear. Some oils also offer increased friction modifiers to help reduce shudder on take off which is a common complaint with all CVT’s.

Recommended Oil Change Service Schedule… 

Audi 01J CVT Multitronic Transmission Filler & Drain Plugs

  • Service your Audi CVT Transmission every 3 years or 60,000kms which ever occurs first.

Carrying out a Fluid Change…

The 01J Transmission does not have a sump and uses one drain plug and also one filler/check plug which are both on the bottom of the transmission (See image to right). The Filler/Check plug has a raised tube which allows for the correct oil level to be achieved duing filling the transmission.

Tool List (See links below)

  • Male M16 Security Drain Plug Socket
  • Male 10mm Hex Filler/Check Plug Socket
  • Hose Barb Filler Adapter
  • Oil Drum with Pump

First drain the fluid and also remove the filler plug and allow to drain for about half an hour. Clean and replace Drain plug (tighten NM). Then fit the Barb filling tool into the filler hole (hand tight) and connect up your pump system. You can now fill the transmission with 4.5 litres of Audi recommended CVT fluid (leave pump connected) and then start the vehicle with shift lever in park position.

Wheels off Ground
If the vehicle has the wheels off the ground you can select drive and reverse and allow the wheels to spin up to 8kph for a few seconds. Then remove the filler fitting and check for oil running out the filler/check hole. If the oil is running out wait until its starts to slow almost to a trickel and fit the filler plug (tighten NM) if no oil runs out add 0.5 litre and check again. (TIP: Try and keep transmission oil temp under 65°C to get a correct oil level reading.)

Wheels on Ground
If the vehicle is on ramps etc you will need to disconnect the filler adapter and fit filler plug (hand tight & with out loosing to much oil) then you can select drive and reverse and allow the gears to engage. You may need to allow the vehicle to move a few centermeters both ways to do this, then remove the filler plug and check for oil running out. If the oil is running out wait until its starts to slow almost to a trickle and fit the filler plug (tighten NM) if no oil runs out add 0.5 litre and check again. (TIP: Try and keep transmission oil temp under 65°C to get a correct oil level reading.)

Conclusion…

The fluid is now change test driver the vehicle and check for any clutch related problems. Some vehicles will need the internal clutch packs recalibrated to help fix delayed or harsh take offs, take off shuddering and delayed engagements. If a take off shudder persist after oil changes and recalibration you can try adding a friction modifier to the oil contact us for more details. admin@furitech.com.au
