Question about 2005 Audi A3

1 Answer

Hi. I have a 2004 Audi A3. PAst number of weeks a light Emission Control System and EPC light come on intermittantly. Sometimes when out for a journey, the car can cut out when stopped at lights and sometimes it runs like a dream. There is 82k on it. Bringing it into a garage tomorrow and would like to know any idea what is causing this and how much on average Id have to pay to get it repaired. Many thanks

Coolant temp sensor or airline.

I had the same problem, replaced the coolant temp sensor for £15 and reset the warning light. 2004 1.6 SE. I'll never go back to Audi for a service. They might as well wear balaclavas.

I still have some problems with the idling but I can live with it (or until I know the real reason) - After £100 diagnostic and me suggesting to them what it might be they said they could do nothing. Surely by the number of comments about the same problem it must be a known fault!

WHAT DOES EPC STAND FOR ?


"Engineering, Procurement, and Construction" (EPC) is a particular form of contracting arrangement used in some industries where the EPC Contractor is made responsible for all the activities from design, procurement, construction, to commissioning and handover of the project to the End-User or Owner.

In case of cars:
The EPC indicator is a standard in Volkswagen and Audi models. These vehicles have drive-by-wire systems that are computer-controlled. When a fault exists with the throttle pedal, throttle body, traction control and cruise control, the EPC warning light illuminates. In many instances, the vehicle's throttle may be limited when this light is illuminated in order to protect the engine. Often, there is just enough power enough to get the vehicle to a service facility for repairs.

Just bought a 2003 Audi A3, the engine light has come on, any idea what this could be for?


First of all you need to access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the ECM. Then the engine light & EPC (Electronic Pedal Control) yellow light will turn OFF.

A3 audi, cutting out while driving, airbag light on always and chugging intermittently at high speed


Hi!

The car may have a problem in the air mass sensor or else in the turbo. The best thing to do is, in first place, to connect a scan tool and check the memory for errors.

The airbag is a independent system. you should also connect a scan tool.

After that, maybe i can help you more.
