Audi A6 exhaust black smoke

A mileage of about 10 million km configuration handbook transmission, the displacement of one. 8L Audi A6 sedan. Buyers replicate: a small sum ECU programmerof black smoke coming out the car motor working throughout the exhaust pipe, exhaust odor.

Pick-up after the take a look at, the engine electric power is basically standard. The link execute self-diagnosis, motor system provides a fault code "00561, mixed fuel adjustment over and above the limit. Execute fault codes Apparent fault code is cleared. Evaluate the lead to, there may be terrible oxygen sensor efficiency.KTAG Examine facts stream (the purposeful route 01-08-007), the idle condition with the 007 groups of knowledge block 1, data (combined gas formation regulate benefit) of -25%, two Place facts (oxygen sensor sign voltage) to 0. 809V . Beneath usual circumstances, the gasoline mixture is shaped the command values ?ought to be the choice of 10% -10%, and as the gasoline injection amount correction sum slight fluctuation. -25% Of your data on the motor command module attempts to cut back the gasoline injection quantity, in an effort to management the focus from the gas mixture within the typical variety. The oxygen sensor sign voltage of 0. 809V, mixed gasoline partial focus, in line with the failure phenomenon of black smoke.

Seen through the basic principle of fuel injection, the motor manage module simple gas injection quantity is set according for the engine pace sign, air movement sensor signal, hence the upcoming ought to focus on examining air stream sensor. Collection functionality route 01-08-002 info to determine if the air flow sensor knowledge (zone four). Air targeted traffic idling for seven. 5 kg / s, significantly greater than with normal -4. 0kg / s. Zone 2 details with the idea in the gas injection time (crankshaft revolution), 3-zone information with the motor cycle injection time (real fuel injection time). Actual fuel injection time is corrected over the basis of your theoretical gasoline injection time from two gasoline truck diagnostic toolinjection time should really be twice the theoretical gas injection time six automobile is nearly the exact same as this Description theory injector time is simply too extensive, the modification following the actual injection time turns into brief. When the amount of money of correction from the gasoline injection time exceeds the limit, there will certainly be a fault code 00561. Dependant on the above mentioned exam effects, prognosis purpose would be the air circulation sensor sign is simply too significant 6 to switch the air circulation sensor fault wholly dominated out.
