Change o2 sensors every 60,000 miles and use iridium plugs they will outlast engine.
check engine light will not come on until sensors are completely shot,this also goes for your mass air flow,had same issues with 99 beetle happened at 80,000 miles,changed all three items ended up with 35mpg after getting 24mpg before fix.parts are cheap on ebay.

Does not sometimes O2 sensor give low voltage or fault code on test, and in the same time it didn't give functioning properly? Someone told me that it may be correct. I wish you answer my question.


Hi Faisal
The only way to find the problem on your Audi is with genuine Audi diagnostics software if you have a defective oxygen sensor it will put your engine management light on.

I have Audi A6 gasoline 2.4 liter motor. The fuel consumption is too much. I hope you can give me the solution for this problem.


Likely, it could be the O2 sensor, stuck or debris in an injector, or weak spark. Fuel pressure tests will point you in the right direction

I have 2.4 liter Audi A6 car gasoline. The consumption now is 25 liters per 100 Km which is too much, it must be 15.4 liters per 100 km How can I solve this problem?


Have you changed the plugs, changed the air filter, etc. Many times a clogged air filter will kill the mileage. Have you had a compression test to see if it is just wore out? All sorts of things need to be checked to answer this.

Does the driving on overdrive mode cause high fuel consumption, because the transmission use the first three ratios mostly?


driving in over drive mode actually is what gives the economy as the engine rpms will be around 300 less than direct drive . Lower rpms = fuel savings
OD should come in around 60 klm/hr and drop out at around 50 klm/hr. When you are accelerating hold the pedal in a set position and watch the rev counter (rpms ) and each gear change you will see the rpms drop and then build back up as the vehicle speed increases At 100klm/hr the revs should be around 3200 rpms or less but if over ( say 3500 rpms) then may be the OD is not coming in. One way to test a box operation is to find a speed shop with a dynomometer and test the gear selections against loads and engine rpms

Driving in overdrive, say on a trip where your speeds are over 65 to 70..Actually saves gas, but using overdrive to drive around town not only uses more gas, but can cause damage to your transmission.
