A mileage about 55000km, ATX motor is equipped together with the Audi A6 sedan. The automobile Auto Key Programmer engine fault indicator light is on, the phenomenon of choking exhaust emissions.

The comprehending that. Car proprietors to acquire second-hand automobile auto diagnostic tool dashboard displays during the close to mileage may be artificially tuned. It reflects the proprietor, the motor vehicle continues to be the failure to fix factory upkeep moments, each individual engine fault indicator lit to crystal clear the fault code would be the rear motor perform back to normal. Working for quite a while, the phenomenon will surface again.

1st, open up the motor compartment lid, the verify engine peripheral lines and vacuum tube, and uncovered no abnormalities; then connection failure detector go through fault codes, tone was failure secondary air injection pump circulation failure (incidental), by using a examination light-weight detection secondary air injection pump connector 車用故障診断ツール of the energy provide terminal, when starting the engine, the check light might be lit, indicating how the usual electricity provide on the pump. Eliminate the secondary air injection pump after the disintegration of inspection, uncovered its impeller has become weakened, so he changed the pump, after which very clear the fault code following the check, almost everything is regular, then allow the car factory.



About twenty times later, the car or truck once more in to the plant preservation, to mirror the above mentioned phenomenon even now exists, and also the engine idling jitter. Fault detector to attach once again to read through the fault code. S one: the cylinder no recognition to the ignition tune the content material with the fault; cylinder i did not identify the ignition; cylinder 2 no recognition on the ignition; cylinder 3 won't recognize the ignition; camshaft timing management solenoid valve malfunction (incidental). Get rid of the spark plug car diagnostic tools wholesale check the electrode coke, exchange the spark plug after the test, the fault persists; Check the ignition coil and diode examination mild to examine just about every cylinder injector manage signal, observed the 1st cylinder, cylinder 2 and 3 cylinder injector command signal if the engine just work commonly, although the engine operate following 10 min. Began to turn out to be usual and irregular (test lights flashing), 4-cylinder, 5-cylinder and 6-cylinder been functioning. Evaluate the resistance of every cylinder injector. Are inside the conventional assortment. Measurement of the initial cylinder, the 2nd cylinder and 3-cylinder gas injector harness, also observed no abnormalities. Due to the fact fault code retrieval, you can find a fault code around the camshaft timing management solenoid valve malfunction ". Decided to verify the very first cylinder as well as the 2nd cylinder and 3-cylinder camshaft timing management solenoid valve, measuring its resistance. Standard; to open valve chamber protect inspection located that the camshaft timing manage solenoid valve chain tensioner seat of bakelite fracture.
