Audi A3 showing yellow indicator lamps 1) engine management system flashing 2) Emission control system 3) diiesel particulate filter whats wrong?

when you turn on your ignition to the point before engaging the starter all your warning lights should light up. The Engine Check Light is very obvious, except they throw convention to the wind and show it as 'Service Engine Soon' lamp 'Malfunction indicator lamp (MIL)'.
Page 63 - Section 2-7 Instruments and controls

Malfunction indicator lamp (MIL) If this indicator lamp comes on steady or blinks while the engine is running, it may indicate a potential emission control malfunction. The malfunction indicator lamp may also come on steady if the fuel filler cap is loose or missing, or if the vehicle runs out of fuel. Check to make sure the fuel filler cap is installed and closed tightly, and that the vehicle has at least three gallons of fuel in the fuel tank. After a few driving trips, the lamp should turn off if no other potential emission control system malfunction exists.

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

My Audi Q7 has an V8 Fsi Engine and the check engine light is turned on ince years. But I cannot pass inspections, so year after year I am hvg those problems. Audi cannot find the problem! Better no more Audi!!!!

OBD2 programs won't normally read Audi's format enough to diagnose the problem or even communicate with the cars control module. may need to hook it to a laptap with Audi program to figure out the problem.

Service reset:

Note: This reset method applies only to vehicles with a fixed maintenance schedule. All other vehicles: reset using special VAG equipment, or similar.


1. Turn the ignition ON.
2. Pull out button [2].
3. "SERVICE IN ???? KM" or "SERVICE !" appears on the display.
4. Pull button [2] until the indicator shows: "----".
5. Press the reset button [1] within 5 seconds.

The system is reset.

ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.
For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.



ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

what ever you do don't go to a audi shop as it will cost you a £1000.00 with out vat and £32.50 for every half hour of there time. try to resync. switch engine on with spare key and remove the remote fob from the key, shut the door and lock the door with the key within 5 seconds press unlock on the first remote to be coded untill the indicators flash once, wait 5 seconds and press unlock again to confirm this memory position. Remove ignition key and test remote if o.k repeat for other remotes adding extra positions by sitting indicators flash. position 2 will be two flashes. if no flashes then get the fault memory read. This may take a few attempts and lots of sweaing. Regards Samantha
