EPC warning light!

Question edited for clarity.
Question moved to Audi A6

The most common causes of an EPC light showing up on your Audi or VW are a faulty throttle body, a faulty ABS sensor, a cracked ABS ring, or a faulty brake pedal switch. Here are a few of the issues that could trigger the EPC light.

Computers are taking over everything on your vehicle. Traditionally, components like the steering, the parking brake, and the gas pedal used to require mechanical linkages. Nowadays, computers and electric motors can take care of all of these functions and more.
Electronic Power Control (EPC) is a computerized ignition and engine management system. It is used by other systems on the car such as stability and cruise control. Any faults with the EPC will likely disable other functions on your vehicle so it is important to keep the system maintained and functional. A warning light on the dash will let you know when an issue has been detected in the EPC system.

What the EPC light means

Since the EPC is used on multiple other systems on the vehicle, it is likely that other warning lights will be illuminated on the dash as well. Typically, the stability control and cruise control will be disabled and their respective lights will be illuminated as well. The check engine light may also come on to show that the engine itself isn't operating at normal efficiency. To try and protect the engine, the computer can limit the vehicle's throttle and the car may feel sluggish as a result.
You will need to get the car scanned for trouble codes that can be used to identify the problem. Once repairs have been done and the codes cleared, everything should return to normal.

Is it safe to drive with the EPC light on?

Like the check engine light, the severity of the problem can vary greatly. If this light comes on, you should have the car checked out as soon as possible to prevent any significant damage from occurring. If your vehicle is limiting your throttle to protect the engine, you should only use the vehicle to take it to get repaired.
Common issues with your car's EPC are malfunctioning sensors which just need to be replaced. However, the issue can be more serious so don't hesitate and have your vehicle checked out as soon as possible.

Unless you have a scan tool or have a friend that has one. You will need to send it in for diagnostics. A code reader may provide some information but will not show live data. The EPC warning light, also known as the Electronic Power Control warning light. The PCM has identified a fault with your Volkswagen's throttle system. The throttle pedal, throttle body, traction control, cruise control or wiring could be to blame.

200 RPM are you sure?

That sounds like a bad connection. Check all connections for the EPC system from the accelerator pedal TPS to the throttle body itself. If that fails you could have a wire in the loom that is broken and makes inertmitent contacts.

"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.

Firstly you need to put a diagnostic machine on for a check as the epc light comes on there is a fault

I am having the same problem on my Audi A4 2004 FSI, lose power whilst driving at speed with the EPC light coming on. Looks like a design fault of some kind with Audi petrol engins, have read a few forums about this but no clear straight answer. Check the link below:

electronic pedal control......the sensor in the electronic gas pedal has a fault

change the pedal sensors if fitted ,not sure it has them though i cannot remember everything ,nothing in my alldata book about a fault with this particular model .but this is a common sort of problem with vehicles with pedal sensors
