Audi Cabriolet 1998 - 1998 ENGINE PERFORMANCE Self-Diagnostics - Introduction


Audi Cabriolet 1998 - INTRODUCTION

If no faults were found during preliminary inspection, proceed with self-diagnostics. If no trouble codes or only pass codes are present after entering self-diagnostics, proceed to TESTS W/O CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).


Audi Cabriolet 1998 - SELF-DIAGNOSTIC SYSTEM


NOTE: It is necessary to generate a PCM readiness code if PCM memory is cleared, battery voltage is disconnected or PCM is disconnected. See CLEARING CODES . If PCM was replaced, see PCM REPLACING .


Audi Cabriolet 1998 - DIAGNOSTIC TROUBLE CODES (DTCS)


The Powertrain Control Module (PCM) can identify malfunctions and store them in memory in the form of a Diagnostic Trouble Code (DTC). DTCs are stored until memory is erased. If positive battery cable or PCM connector is disconnected, DTCs are erased.


Audi Cabriolet 1998 - MALFUNCTION INDICATOR LIGHT (MIL)


MIL will illuminate if a failure occurs with Powertrain Control Module (PCM) or Transmission Control Module (TCM). If a failure occurs associated with TCM, see IMPORTED TRANSMISSION SERVICE & REPAIR section.

When ignition is turned on, MIL should come on. When engine is started, MIL should turn off after a couple of seconds. If MIL does not turn off after engine is started, or if MIL comes on while driving, retrieve Diagnostic Trouble Codes (DTCs). See RETRIEVING CODES .

If MIL lights continuously, a malfunction is present that will cause an increase in emissions. If MIL starts to blink, a malfunction is present which may lead to catalytic converter damage. Repair these failures as quickly as possible. For some failures, MIL is only turned on after failure occurs after 2 successive trips with cold engine starts preceding failure.

Some failures will set a DTC which will never cause MIL to light. An example of a failure that could occur and not cause MIL to light would be a FUEL LEVEL TOO LOW signal generated on a A4 1.8L model.

NOTE: If MIL is on continuously and no DTCs are stored, perform MIL check. See MIL CHECK . If MIL never illuminates, see MIL CHECK .


Audi Cabriolet 1998 - HARD FAILURES


Hard failures (also called static malfunctions) cause MIL to come on and a code to set in Powertrain Control Module (PCM) memory. A code that sets as a result of a hard failure will not be erased automatically when the problem is eliminated. These codes must be erased manually.


Audi Cabriolet 1998 - INTERMITTENT FAILURES


When an intermittent failure occurs, MIL comes on and a Diagnostic Trouble Code (DTC) sets. Powertrain Control Module (PCM) stores DTC as sporadic. Intermittent (sporadic) failures will be erased by PCM if failure does not occur again within 40 engine starts on Cabriolet, or after 50 engine starts with engine reaching operating temperature on 1.8L and 2.8L (except Cabriolet). Intermittent failures may be caused by problems with a sensor, connector or wiring. See INTERMITTENTS in TESTS W/O CODES article.


Audi Cabriolet 1998 - RETRIEVING CODES


NOTE: If Malfunction Indicator Light (MIL) is on continuously and no DTCs are stored, perform MIL check. See MIL CHECK . If MIL never illuminates, see MIL CHECK .


Audi Cabriolet 1998 - Visual Inspection


Prior to retrieving Diagnostic Trouble Codes (DTCs), perform a comprehensive visual inspection of ground connections located on intake manifold, ensure battery negative cable is okay, and check ground cable between engine and vehicle body. Repair as necessary. Check vacuum hoses for breakage and blockage. Check electrical wiring and connectors for damage and corrosion. Repair as necessary.

NOTE: Manufacturer does not provide procedure for retrieving DTCs without scan tool. If using Volkswagen Audi Group (VAG) 1551 scan tool for diagnosis, follow manufacturer's instructions for operation. VAG 1551 is recommended for diagnosing DTCs.


Audi Cabriolet 1998 - Retrieving Codes


  1. Locate Data Link Connector (DLC) located behind cover under left side of steering column. See Fig. 1 . Connect VAG 1551 scan tool or generic scan tool to DLC. Turn ignition on or start engine and let it idle. If engine will not start, crank engine for at least 6 seconds. See appropriate table under DTC IDENTIFICATION .
  2. If no communication is possible with PCM, verify connection for scan tool is okay. If scan tool connection is okay, check wiring harness between DLC and PCM for open or short circuit. See WIRING DIAGRAMS article. Repair as necessary. On A4, PCM is located in left rear corner of engine compartment inside electrical box. On Cabriolet, PCM is located in floor cavity under passenger side carpeting. On all models, if wiring harness is okay, PCM is possibly faulty. See PCM VOLTAGE CHECK .

Audi Cabriolet 1998 - PCM CODING


NOTE: When using Volkswagen Audi Group (VAG) 1551 scan tool, follow manufacturer's instructions for operation. VAG 1551 scan tool is necessary to perform PCM coding.

If Powertrain Control Module (PCM) is replaced, it is necessary to code new PCM. If new PCM is not properly coded, the following problems may occur:

  • Driveability problems (i.e., harsh shifting).
  • False malfunctions stored in PCM memory.
  • Increased fuel consumption.
  • Increased exhaust emissions.
  • Reduction in transmission life.
  • All PCM functions are not carried out (i.e., EVAP system operation).

Connect VAG 1551 scan tool to Data Link Connector (DLC). Following manufacturer's instructions, access PCM coding information using VAG 1551 scan tool. For PCM coding options, see appropriate PCM CODING OPTIONS table.

As an example, a properly coded PCM for an A4 model with Front Wheel Drive (FWD) without traction control and 5-speed manual transmission would look like 06001 on the VAG 1551 scan tool.

NOTE: After coding PCM and starting engine for first time, allow engine to idle for several minutes so PCM can go through a learn function. Idle speed may be erratic while PCM is learning.
