TECHNICAL SERVICE BULLETIN

Reference Number(s): 2024632/3, Date of Issue:  December 20, 2010
AUDI: A4, A6

CONDITION

  • MIL on.
  • Misfire DTCs (P0300, P0301, P0302, P0303, P0304, P0305 or P0306) are stored in the ECM.
  • Freeze frame data indicates DTCs stored during cold start (engine coolant temperature between 18 - 36°C).

TECHNICAL BACKGROUND

Software update is needed.

PRODUCTION SOLUTION

New software in the 4F2 910 559 H Control Module (J623) addressed the condition.

SERVICE

  1. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
  2. Update the ECM using the SVM action code as listed in the table below, if necessary.
  3. Perform a short test drive.
  4. Verify repair during cold start next morning via recording MVB 14 and 15 (ambient temperature between 50 - 80°F).

Tip:  Based on normal fuel quality variation under certain ambient conditions some single misfires may be recorded during cold start (catalytic converter heating phase). This will have no negative effect, no further investigation is needed.

Condition

REVISION HISTORY
Revision Date Purpose
2 - Revised Service
Revised Warranty
1 4/1/2010 Original publication
  • Campaign 28F2/J1 has been performed. (Model year 2002 - 2007 only)
  • Rough idle.
  • The MIL is flashing or constantly illuminated.
  • One or more of the following DTCs are stored:
    • DTC P0300  (Random/Multiple Cylinder Misfire Detected)
    • DTC P0301 - P0312  (Cyl.1 Misfire Detected - Cyl.12 Misfire Detected)
  • Engine may have reduced performance without significant loss of power or stalling.

Technical Background

Generation II coils listed in Campaign 28F2/J1 generally are not the root cause of engine misfire conditions. Replaced ignition coils have commonly been related to conditions such as:

  • Incorrect installation of ignition coils.
  • Loose or damaged electrical connections.
  • Circuit grounds.
  • Poor fuel quality.
  • A number of other reasons not directly related to ignition coil operation.

Proper GFF misfire diagnosis must be followed before replacing any ignition coils.

Production Solution

Not applicable.

Service

Ensure all campaigns and applicable TSBs have been performed

Due to multiple causes for engine misfire, please ensure all campaigns and applicable TSBs have been performed.

Repeat repairs must be carefully addressed to identify the root cause of the concern. Please utilize proper diagnosis steps to ensure that the vehicle is repaired properly and that the concern has been identified, repaired and verified.

Obtain information from the customer

To repair the vehicle correctly, obtain as much information as possible from the customer about the symptoms of the condition and when it occurred.

  • In what situation (turning, etc.) does the condition occur?
  • Under what environmental conditions (road conditions, weather, temperature, start conditions, etc.) does the condition occur?
  • What is the operating situation of the vehicle (activated electrical equipment, gear selection, etc.) when the condition occurs?
  • Can the complaint be reproduced?

Workshop procedure

  1. Read out the data memory of all engine control modules, and note the environmental conditions on the DTC log.
    1. If there are other entries in addition to combustion misfires, address the other entries before addressing the cylinder misfires.
    2. If DTC P0301 - P0312  (Cyl.1 Misfire Detected - Cyl.12 Misfire Detected) is accompanied by P1250  (Fuel level too low), it is likely the faults occurred due to a low fuel level and not a malfunction of the coils.
    3. Review all applicable TSBs related to cylinder misfires and ECM software improvements before diagnosing the misfire condition. For example, if data shows that a DTC was set during cold start, search ElsaWeb for TSBs related to cold start misfires.
  2. Try to duplicate customer complaint based on the environmental conditions at the time the DTC was set. The freeze-frame data gives important indicators for the traceability of the complaint, in particular if it occurs sporadically or at cold start.
  3. Review the vehicle repair history for previous misfire or maintenance service that could be related to the current complaint.
  4. Observe the requirements of Guided Fault Finding. Perform Guided Fault Finding in full according to the proposed sequence (test plan). Do not skip any steps.
  5. Complete Guided Fault Finding correctly and set the readiness code.

    Tip:  This is important to ensure that no subsequent faults occur due to the misfire.

  6. In the case of single cylinder misfires:
    1. Before replacing components,  determine whether the misfire migrates to the other cylinders after exchanging the coils. If necessary, perform a test drive to ascertain this.
    2. If the misfire migrates to the cylinder the coil was moved to:
    • Read the DTC memory, print and attach both diagnostic logs (before and after) to the repair order.
    • Return both coils to their original cylinders, and only replace the defective coil.
  7. Verify repair under the same environmental conditions (e.g.: engine speed, engine load value, vehicle speed, coolant temperature, intake air temperature, ambient air pressure, voltage at terminal 30, etc.) as noted on the DTC log.

Warranty

For payment processing both Guided fault Finding Logs must be documented identifying that the issue changed cylinders during the test. All claims are subject for review.

CONDITION

  • MIL on.
  • Misfire DTCs (P0300, P0301, P0302, P0303, P0304, P0305 or P0306) are stored in the ECM.
  • Freeze frame data indicates DTCs stored during cold start (engine coolant temperature between 18 - 36°C).

TECHNICAL BACKGROUND

Software update is needed.

PRODUCTION SOLUTION

New software in the 4F2 910 559 H Control Module (J623) addressed the condition.

SERVICE

  1. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
  2. Update the ECM using the SVM action code as listed in the table below, if necessary.
  3. Perform a short test drive.
  4. Verify repair during cold start next morning via recording MVB 14 and 15 (ambient temperature between 50 - 80°F).

Tip:  Based on normal fuel quality variation under certain ambient conditions some single misfires may be recorded during cold start (catalytic converter heating phase). This will have no negative effect, no further investigation is needed.
