A mileage of about 73,000 km in the 2011 Audi A6L two.0T sedan. Customers report: Following the automobile speed exceeds 120km / h, the engine appears critical shake phenomenon. Varying degrees of every cylinder are missing cylinder phenomena take place, as well as the frequency jitter of each cylinder is not really very distinctive, no principles to comply with, whilst the engine fault light is lit, but closed again after the ignition switch, the car is usually begun commonly. In case the low velocity (the velocity at 100km / h or much less), all typical car. According for the proprietor described the substantial frequency of automobile failure, you will find 10 high-speed eight instances there are going to be a significant shake phenomenon. This car or truck checked numerous times to verify the end result could be the encouraged replacement turbocharger assembly owners in other repair shop.
Troubleshooting:
1. Diagnostic connection x431 iv. That means fault code is: a turbocharger as well as the throttle connection error, test the environmental circumstances, the speed at 140km / h or so, the engine velocity About 3800r/min, determined by effects of diagnostic tests, inspection from the turbocharger air intake throttle valve to your pipe leaks, and in addition once the car is began, the intake region spray carburetor cleaners, engine speed see Have clear runout improvements.
2. Check for leaks. The writer because of prolonged maintenance of such autos, the turbocharger to test for leaks at the throttle, summed up a set of their very own way, in situation the automobile is started off, clear away the air filter, then hand fully blocked air movement meter inlet, immediately after a while, a feeling in the engine into the vacuum with out improvements, should the vacuum slowly finding smaller, and that is the place there exists a leak inside the middle; If there's no change in the intensity of the vacuum, it shows that there are actually no leaks. Prior process of operation is: prior to getting rid of bars, 1 by one particular to check out the various components, time-consuming, labor intensive and laborious. Just after checking numerous exams and observed the components will not leak. And from the situation on the car start, the carburetor on the consumption region spray cleaners, engine velocity isn't going to change, no leaks also described.
3. At this time, the upkeep impasse, it definitely the owner explained, turbochargers broken and need to be replaced? Substitute the turbocharger is really a fairly substantial servicing tasks. Cautious analysis autel ds708 turbocharger connection standing of every interface: just checked pressurized piping, only a turbocharger connected on the consumption region of your gas procedure, and its purpose is usually to maximize the air pressure. The turbocharger also includes a cylinder head cover by using a relatively modest pipe connected to your cylinder head cover by means of a stress regulating valve linked for the throttle level, the line connection is formed within the intake manifold once the supercharging stress, the pressure regulator valve housing to close the examine valve, a blow-by gas passage in the crankcase by the cylinder head cover is directed to the front from the turbocharger, and once the intake manifold vacuum is present, the blow-by gas is introduced directly into the intake gasoline manifold. This line is adjusted to alter the stress regulating valve within a check valve, a strain regulating valve when the inner injury when traveling at high pace, forming a considerable supercharging the consumption manifold strain, need to be directed towards the turbo forward with the crankcase pressure and also the exhaust gasoline introduced OBDII diagnostic scanner in to the consumption manifold, that is forming the additional intake air. At this time every single cylinder engine will likely be irregular jitter.
4. Just after changing the exhaust valve testing, troubleshooting.
