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.

Warning light on audi a4

This is the indicator for ESP (stability control). If you look on your dash, you'll see a button with, you guessed it, ESP written on it. This allows you to turn your stability control on and off. If your light is on constantly, try pushing the ESP button. If it flashes on and off (ie during hard driving) this simply means it is working.

2003 audi a4 1.8t ECU/emission control system warning light flash

No I am a mechanic at Audi. The problem is that the the air flow to the central tappets may be causing the air flow sensor to trip and that is why. Try putting a small amount of WD40 into the petrol and that will work, its a very common problem.

A vehicle's Emission Control Light is a generalized indicator that there is fault or possible malfunction in the vehicle's operating system. In some cases, these warning lights will come on if a gas cap is not fully closed. It could any one of a number of sensors such as the o2 sensor or map sensor. The thing to do is have a reputable mechanic/technician run a diagnostics test on the vehicle.
