Safety Precautions

CAUTIONThe fuel system is under pressure! Before opening the system, place rags around the connection area. Then release the pressure by carefully loosening the connection. The engine section of the fuel system, after the high pressure pump, is under extremely high pressure! When working on the engine or the fuel injection system, the pressure must be relieved to residual pressure before opening the high pressure components --> 24 - FUEL INJECTION SYSTEM . Place sources of flame, e.g. cigarette lighters, as well as those sources of others in the area, out of reach. These can ignite fuel vapors. The use of nails, paper clips, or another unauthorized materials to back-probe electrical harness connectors is strictly prohibited and may cause damage to the electrical harness connectors, terminal ends or damage to a component. Use only the manufacturers test lead kit or an equivalent aftermarket test lead kit for back-probing all electrical harness connectors.

Perform the following steps before beginning work on the fuel supply system

  1. Disconnect the battery Ground (GND) cable with the ignition switched off --> «27 BATTERY, STARTER, GENERATOR, CRUISE CONTROL»(/audi/a4/b7-2004-2009/remont/cruise-control-systems/#electrical-equipment) 27 BATTERY, STARTER, GENERATOR, CRUISE CONTROL for ELECTRICAL EQUIPMENT, CABRIOLET .
  2. Open the fuel filler flap briefly and then close again.

When removing and installing components from full or partially full fuel tanks, observe the following

  1. The fuel tank must only be partially full. How much fuel can remain in the fuel tank may be read in the respective work description. Empty the fuel tank if necessary.
  2. Before starting work, switch on the exhaust extraction system and place an extraction hose close to the installation opening of the fuel tank to extract escaping fuel fumes. If no exhaust extraction system is available, a radial fan (as long as motor is not in air flow) with a displacement greater than 15 m 3 /h can be used.
  3. Prevent fuel from contacting the skin! Wear fuel-resistant gloves!

Observe the following when removing and installing the fuel tank

  1. Empty the fuel tank for weight reasons.

Rules for Cleanliness

When working on the fuel supply/injection system, pay careful attention to the following rules of cleanliness

  1. Thoroughly clean all connections and the surrounding area before disconnecting.
  2. Place parts that have been removed on a clean surface and cover them. Do not use fluffy cloths!
  3. Carefully cover over opened components or seal, if repairs are not performed immediately.
  4. Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored unpacked (e.g. in tool boxes etc.).
  1. When the system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.

Evaporative Emissions (EVAP) System

EVAP System, Leak Detection

Function

The leak detection system recognizes leaks in the complete fuel system, including the fuel tank, EVAP canister and the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80.

On the mechanical side, the leak detection system consists mainly of a vacuum-driven diaphragm pump equipped with a reed contact on the actuation rod of the pump diaphragm. The pump is supplied with vacuum via the engine intake stroke.

  1. When leak detection is activated, the diaphragm pump pumps the fuel system up to 20 - 30 mbar. The pump diaphragm is then moved out so that the reed contact at the operating rod remains in the "open" position.
  2. During the leak diagnosis, the reed contact is monitored to check if it remains open within 10 seconds. This indicates the system is sealed.
  3. If the pressure falls (indicating a leak), the diaphragm moves back and the reed contact closes.
  4. If the reed contact closes within 10 seconds of leak detection time, a further test is performed: In this case the diaphragm pump pumps four times again. The Engine Control Module (ECM) J623 measures the time for each of the four pumps until the reed contact is closed again. From that, the control module can recognize a "small leak" (greater than 1 mm in diameter) or a "large leak".

Leak diagnosis is activated automatically shortly following every engine start. If a malfunction is determined, an entry is made to the Diagnostic Trouble Code (DTC) memory. The Malfunction Indicator Lamp (MIL) K83 in the instrument cluster lights up if the malfunction is recognized for two subsequent starts.

EVAP System, Checking for Leaks

Special tools, testers and auxiliary items required

  1. Smoke tester.
  2. EVAP and Fuel Supply System Vacuum hose and line routing diagram.

Note. Secure all hose connections using hose clamps appropriate for the model type . Replace seals and gaskets when performing repair work.

Leak checking

  1. Using a Smoke tester , check the Evaporative Emission (EVAP) canister system for leaks.

Note. Always follow the manufacturers directions for the proper installation and operation of the Smoke tester being used.

If a leak is found

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system. Note the following

CAUTIONThe fuel system is under high pressure! Before opening high pressure components of the fuel injection system, pressure must be relieved to residual pressure. Wrap a clean rag around the connection and relieve residual pressure by carefully loosening the connection.
  1. Always switch off ignition before disconnecting or connecting lines of the fuel injection and ignition system, including test leads.
  2. During some of the tests, a Diagnostic Trouble Code (DTC) may be recognized and stored by the control module. At the end of all tests and repairs, the DTC memory should be checked and, if necessary, erased. After erasing the DTC memory, a readiness code must be generated.
  3. Always switch the ignition off before cleaning engine.
CAUTIONThe battery must only be disconnected and connected with the ignition switched off, since the Engine Control Module (ECM) J623 can otherwise be damaged. Observe procedures for disconnecting the battery --> 27 BATTERY, STARTER, GENERATOR, CRUISE CONTROL 27 BATTERY, STARTER, GENERATOR, CRUISE CONTROL for ELECTRICAL EQUIPMENT, CABRIOLET .

Observe the following if test and measuring instruments are required during a test drive

CAUTIONTest and measuring equipment must always be secured to the rear seat and be operated from there by a second person. If test and measuring instruments are operated from the front passengers seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is deployed.

Even minor contaminations can lead to malfunctions in the fuel injection system. When working on the fuel supply/injection system, pay careful attention to the following rules for cleanliness

  1. Thoroughly clean all unions and adjacent areas with engine or brake cleaner and dry before disconnecting.
  2. Plug open lines and connections immediately with appropriate protective caps.
  3. Place removed parts on a clean surface and cover. Use lint-free cloths.
  4. Install clean components: Remove replacement parts immediately prior to installation. Do not use parts that have been stored unpackaged (e.g. in tool boxes etc.).
  1. When the system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.
  2. Separated electrical connectors: Protect from dirt and moisture. Make sure connections are dry when reconnecting.

Ignition System, Servicing

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following

CAUTIONObserve the following for all installations, especially in the engine compartment due to lack of room: Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed. Watch for sufficient clearance to all moving or hot components. Fuel system is under pressure! Before opening system, place rags around the connection point. Then release pressure by carefully loosening connection. Test equipment must always be secured to the rear seat and operated by a second person. Test and measuring equipment that is operated from the passenger seat, the person seated could be injured in the event of an accident involving deployment of the passenger-side airbag. Do not touch or disconnect ignition wires when engine is running or turning at starting RPM. Only disconnect and reconnect wires for injection and ignition system, including test leads, if the ignition is turned off. The use of nails, paper clips, or another unauthorized materials to back-probe electrical harness connectors is strictly prohibited and may cause damage to the electrical harness connectors, terminal ends or damage to a component. Use only the manufacturers test lead kit or an equivalent aftermarket test lead kit for back-probing all electrical harness connectors.

If the ECM recognizes a malfunction that leads to increased emissions values, it indicates them by lighting the MIL which is located in the instrument cluster.

The ECM switches on the MIL after the ignition is switched on. Shortly after the engine is started, The MIL goes out if the ECM does not detect a malfunction that increases the emissions values.

If the ECM recognizes a malfunction that leads to increased emissions during the operation of the engine, the ECM switches on the MIL and an entry is stored in the DTC memory of the ECM.

CAN Data Link

CAN is an acronym for Controller Area Network.

The ECM communicates with all databus capable control modules by a CAN Data Link.

The databus capable control modules (i.e. Engine Coolant temperature Sensor) are connected by two data bus wires which are twisted together (CAN_High and CAN_Low), and exchange information (messages) to the ECM. Missing information on the databus is then recognized and stored as a malfunction.

The ECM illuminates the MIL through the CAN data link and tells the MIL to turn on, turn off, or blink.

Electronic Power Control Warning Lamp

EPC is an acronym that stands for the Electronic Power Control (E-gas).

The ECM monitors all EPC components after the ignition is switched on.

If a malfunction is recognized in the EPC system during the operation of the engine, the ECM switches on the EPC which is located in the instrument cluster and an entry is stored in the DTC memory of the ECM.

Diagnostic Modes

Diagnostic Modes Description

The information provided in Modes 01 through 09 displays the various levels of emission related data that may be monitored, as well as the ability to retrieve and read stored DTC trouble codes , erase stored DTC trouble codes, generate readiness codes, and select the various PIDs and Test-IDs used within the modes to monitor the engine, and emission related component parameters.

Before performing any pin point test or component diagnosis, a preliminary check must be performed.

Check the Technical Bulletins for information that may supersede any information included in this article.

  1. Connect the scan tool.
  2. Switch the ignition on.
  3. Using the scan tool, check for any stored or related DTCs.

If other DTCs are stored

  1. Repair these DTCs first before performing the following procedure.

If no other DTCs are stored

  1. Using the scan tool, erase the DTC memory. Refer to --> «Diagnostic Mode 04: Reset/delete Diagnostic Data»(/audi/a4/b7-2004-2009/remont/cooling-fan/#32l-v6-4v-generic-scan-tool-engine-code-bkh__diagnostic-mode-04-resetdelete-diagnostic-data) .
  2. Perform a road test to attempt to duplicate the customers complaint.

If the DTC returns

  1. Perform the diagnostic procedure.

If the DTC does not return

  1. The fault is intermittent or a sporadic condition may exist.
  2. Check the suspected component, electrical harness and electrical harness connectors for damage, corrosion, loose or broken terminals.
  3. If necessary, repair the faulty wiring connection.
  4. Perform a road test to verify the repair.

If the DTC returns

  1. Perform the diagnostic procedure.

If the DTC does not return

The fault may have been the result of a loose electrical connection.

  1. Generate readiness code. Refer to --> «Readiness Code»(/audi/a4/b7-2004-2009/remont/cooling-fan/#32l-v6-4v-generic-scan-tool-engine-code-bkh) .
  2. End of diagnosis.

Readiness Code

Readiness Code Description

Diagnostics are performed at regular intervals during normal vehicle operation. After repairing an emissions related system, a readiness code is generated by road testing the vehicle.

If a malfunction is recognized during the drive cycle, it will be stored in the DTC memory.

The OBD drive cycle operation will be monitored with a hand held diagnostic tool. Consult the manufacturers instruction manual for correct tool operation.

The readiness code is erased every time the DTC memory is erased or any time the battery is disconnected. If the DTC memory has been erased or the battery is disconnected, a new readiness code must be generated.

Only erase the DTC memory if a DTC has been stored.

General Recommendations

Most monitors will complete easier and quicker using a steady-foot and smooth acceleration during the drive cycle operation, cruise, and acceleration modes.

Operating Conditions

For the EVAP monitor test, the coolant temperature and the ambient air temperature must be between 10°C and 35°C with a difference between them no greater than 4°C. The ambient air temperature must not change more than 4°C during the drive cycle procedure (e.g. when driving out of a heated workshop in the winter).

Test requirements

  1. Erase the DTC memory.
  2. Coolant temperature must be between 80°C and 110°C.
  3. The Intake Air Temperature (IAT) must be between 10°C and 35°C.
  4. Battery voltage must be a minimum of 12.5 volts.
  1. Fuel tank level 1/4 to 3/4 full.
CAUTIONWhen performing the drive cycle operation, pay strict attention to driving conditions and please observe and obey all posted speed limits. Failure to follow these instructions may result in personal injury or possible death.

Drive Cycle Procedure

  1. Connect the diagnostic tester.
  2. Switch the ignition on and start the vehicle.
  3. Idle the vehicle for 2-3 minutes. This executes the O2S Heater, Misfire, Secondary AIR, Fuel Trim, and Purge system monitors.
  4. Drive the vehicle at 45-55 mph for a continuous 7-minute period, avoid stopping. This executes the EVAP, O2S, Fuel Trim, and Misfire monitors.
  1. Accelerate the vehicle to an engine speed of 5000 RPM (with automatic transmission use the tip-tronic mode); lift off the throttle until the engine speed is around 1200 rpm. This executes the fuel cut off
  2. Accelerate the vehicle smoothly to 60-65 mph, cruise constantly for 5 min, this executes the Catalyst; O2S, Misfire, Fuel Trim, and Purge System monitors.
  3. Decelerate and idle the vehicle again for 3 minutes. This executes the Misfire, Secondary AIR, Fuel Trim, and Purge system monitors.
  4. Check the status of the readiness code.

Note. Depending on the diagnostic tester used. The readiness code status may be displayed as complete, passed or OK.

  1. If any engine monitor fails the drive cycle test. Repeat the drive cycle test until all engine monitors have successfully run through and passed.

Note. When repeating the drive cycle operation for a failed EVAP monitor or thermostat-monitor, allow the engine to cool until the coolant temperature and the ambient air temperature are be between 10°C and 35°C with a difference between them no greater than 4°C is observed and repeat the drive cycle operation.

If the drive cycle operation fails again.

  1. Check the DTC memory for stored DTCs.

Repair the vehicle if necessary.

  1. Repeat the drive cycle operation until all engine monitors have successfully run through and passed.
  2. Remove the diagnostic tester and switch the ignition off.
  3. End of operation.
