Audi delay

June 4, 2013
Owners of certain Audi vehicles may complain about intermittent or no drive at startup when selecting driving mode D or R; and the vehicle may enter limp mode (can only be driven in 3rd gear). This delayed engagement when cold or no-drive on first engagement may be accompanied by DTC P2700, P2701, P2702, P2703 or P0730.

Owners of certain Audi vehicles may complain about intermittent or no drive at startup when selecting driving mode D or R; and the vehicle may enter limp mode (can only be driven in 3rd gear). This delayed engagement when cold or no-drive on first engagement may be accompanied by DTC P2700, P2701, P2702, P2703 or P0730.

Models affected include 2010 A4 with 0B6 gearbox, 2008-2010 A5/S5 with 0B6 gearbox, 2008-2010 A6 with 09L gearbox, 2008-2010 A8 with 09L or 09E gearbox, and 2010 Q5 with 0B6 gearbox.

In rare circumstances, if the vehicle was in motion and the ATF strainer becomes loose, the transmission may go into limp mode and can only be driven in 3rd gear.

In cold conditions, the gearbox shifts with a depay. In hot conditions, suction noises occur.

The following DTCs may be stored in the transmission control unit:

P0730 (transmission monitoring incorrect gear ratio)

P2700 (clutch A implausible)

P2701 (clutch B implausible)

P2702 (clutch C implausible)

P2703 (clutch D implausible)

Because of a design change, the ATF strainer can come loose from the guide of the ATF pump intake duct. As a result, air can be drawn in. Air causes the oil to foam, which prevents the clutches from closing completely. An optimized ATF filter was developed as a solution.

  1. Check the gearbox control unit for DTCs. If there are no faults stored but the concern can be duplicated, proceed to Step 2. If one or more DTCs are stored, proceed to Step 3.
  2. Check the ATF level per ELSA instructions. If the fluid level seems too high and foamy due to air mixed with the ATF, proceed to Step 3. If the fluid is at the correct level and the fluid is not foamy, open a TACS contact and call the Audi Technical Assistance Center.
  3. Drain the ATF into a clean container and remove the ATF pan.
  4. If the filter was found in the bottom of the pan, proceed to Step 6.
  5. If the filter is still seated in the valve body, try to remove it with light force. When removed, if the filter seal remained behind in the valve body or is not fully installed on the neck of the filter, proceed to Step 6. If the seal is fully installed on the filter, open a TACS contact and call the Audi Technical Assistance Center.
  6. Obtain a new ATF filter. Check whether the new filter is the improved version with the numbers 22222 and 33333 printed on the top of the filter. If numbers are not printed on the filter, DO NOT install it. Return the part and obtain the correct new-version filter.
  7. Replace the ATF filter according to the repair manual. Make sure that the magnets in the oil sump are not stuck on the underside (metal side) of the loose ATF filter and are not removed with the old strainer. The magnets must be reinstalled in the pan to protect the transmission from metallic particle abrasion.
  8. If there are complaints of gear shift quality after replacing the ATF filter, clear the adaptations in the test plan and then perform the GFF or Guided Functions Adaptation Drive.
