In this article, we will tackle how to fix your Volkswagen’s EPC warning light in great length, so that you can learn some DIY tips and save on some labour prices, especially during South Africa’s financially tough times. 

Brief Description Of Your Volkswagen’s EPC Warning Light 

Before learning how to fix your Volkswagen’s EPC light, it is important to understand the purpose and the role that this warning light plays in your vehicle’s overall performance. The Electronic Power Control (EPC) warning light of your vehicle is mainly responsible for notifying drivers of any faults within the throttle system. Fault indications on your vehicle’s EPC warning light can be caused by failure from the: pedal, traction control, and cruise/throttle body. If you're now wondering whether a functional EPC light is important, the answer is yes! 

Each of these above-mentioned features individually plays a role of utmost importance when it comes to your vehicle’s overall performance. Therefore, a functional EPC light can greatly improve regular monitoring and maintenance.

Simplified Tutorial: How To Fix Volkswagen Electronic Power Control Warning Light?

Read down below to learn the different methods to fix your vehicle’s EPC warning light. 

Method 1: Reset Your VW’s EPC Warning Light. 

By using your vehicle’s owner manual book, you will be able to locate the engine module unit (EMC). Connect your vehicle’s data link connector to a diagnostic machine (Diagnostic Trouble Codes) output. Refer to the available reading on the diagnostic machine-  this will indicate the exact fault, giving you ample time to diagnose the necessary fault. A bonus feature to pay attention to is the DTC light that only goes off once all faults have been dealt with accordingly. Alternatively, you may also reset your Volkswagen’s ECM using the same diagnostic machine. 

Method 2: OBD2 Scanner. 

If you are in the possession of an OBD2 scanner while currently detecting EPC failure- this device may be one of your favourites going forward! This device does not only read your vehicle’s engine control unit- but the steering, transmission and ABS unit as well. An OBD2 scanner is foolproof, meaning that as long as you are “cell phone literate”  you can read the diagnosis off your cell phone via Bluetooth. This will enable you to properly locate underlying issues and address them before incurring additional failures and expenses. 

Method 3: Fix Your VW’s EPC Without Tools 

When choosing this method you do not require additional tools, therefore, if the first two methods were out of your means and reach, this may help. Start your vehicle’s engine while allowing it to run for a few minutes before switching off. Start your vehicle’s engine once again, while pushing down the accelerator with your foot. If this has not turned off your EPC warning light as yet, now would be a good time to check electrical connections along with the throttle body. 

Why Your Volkswagen’s EPC Warning Light May Be On:

• Throttle body failure.

• Poor electrical connection.

• Power steering failure.

• Malfunctioning ABS sensor.
