Reprogramming of Engine Control Module and Replacement of Malfunctioning Oxygen Sensor

The check must be performed with the engine running and heated rear window switched on. Switch OFF the ignition and visually locate the damage. Proceed with checking any other lines as necessary. Once the damaged line is identified, repair utilizing the Repair kit by Permatex ITEM 09117.

This applies to Mechanical Injection Style Diesel Engines, Pumpe Duse Style Diesel Engines and the new Common Rail Style Diesel Engines.

When installing an engine, flywheel or transmission, please follow the installation procedures outlined in ELSA. For the flywheel/flexplate, please be certain the correct shim is installed between it and the crankshaft (reference VWIQ120). When installing a torque converter, press the torque converter hub through the seal as far as the first stop. Turn the torque converter while pushing toward the transmission using light force, until the cut outs in the torque converter hub lock into the pump wheel plate. The torque converter slides in. The torque converter is installed correctly if it is easy to turn by hand and if it fits evenly in the transmission bell housing. Additionally, it should spin freely when the transmission bell housing bolts are torqued to the engine block, prior to installation of the flywheel to converter bolts (reference VWIQ121).

PRND12 is not reading correctly in the MFI, DO NOT replace the ignition switch, lock cylinder, or lock housing assembly. Instead, be sure the Ignition lock solenoid is working properly and/or check that the N376 (called the "catch"), is connected to the lock housing. In some cases you may get a fault code 00194 009 Ignition key removal from lock open circuit/ short to earth. Use MVB 5 in address word 16-Steering Column Electronics for an aid in diagnosis. Please be certain to use the VIN in ETKA to obtain the latest part number(s) available.

of Malfunctioning Oxygen Sensor): Volkswagen has found that the oxygen sensor in the upper part of the exhaust system could fail under certain conditions, potentially causing a vehicle to exceed Federal and/or California emission standards, or to experience increased fuel consumption. ?Thermal shock? within the sensor caused by moisture accumulation could cause oxygen sensor failure. If the oxygen sensor fails, the vehicle?s "check engine" light on the dashboard will illuminate. The corrective action taken for this issue was to Check the emission control system for proper function, reset electronically the engine?s control module and replace the oxygen sensor, if necessary.

consumption standard of up to 0.5 quarts per 600 miles, or 0.5 liters per 1000 km. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. This document informs of oil consumption tests to check a vehicles performance.

consumption standard of up to 0.5 quarts per 600 miles, or 0.5 liters per 1000 km. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owners Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature and road conditions. Further factors include the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.

The fan control module may send a brief voltage signal to the clutch and then shut it off due to an open or high resistance in the coil circuit. The coil resistance should be between 3.5 and 4.5 ohms. If the reading is high or low when checked at the fan module, be sure to double check right at the coil to rule out any wiring concerns. Additionally, check ground circuit integrity for the clutch coil.
