00:00If your VW Polo's EPC light suddenly turned on, don't panic.

00:05This is one of the most common problems Polo owners face.

00:09In this video, we'll explain the real reasons behind the EPC warning and the symptoms you should look for.

00:16We'll also show you the quick fixes you can apply before it becomes a costly repair.

00:22A dirty or misaligned throttle body is the number one reason the EPC light appears.

00:28You may notice rough idling, hesitation while accelerating, or reduced engine power.

00:36Quick tip. Cleaning the throttle body and performing a throttle adaptation usually solves the issue.

00:42A faulty brake light switch triggers the EPC warning immediately.

00:47Symptoms include brake lights not responding correctly or jerky gear shifts in automatic variants.

00:53Quick fix. The brake light switch is inexpensive and easy to replace.

00:59When this sensor fails, the ECU receives wrong throttle signal.

01:05Drivers usually experience delayed throttle response or the EPC and check engine lights together.

01:11A diagnostic scan will confirm the fault and replacing the pedal assembly often fixes it.

01:18Dirty or failing sensors confuse the ECU, causing the EPC light to activate.

01:25Symptoms include poor fuel economy, uneven idle, or weak acceleration.

01:30Quick fix. Cleaning the MAF sensor or replacing a damaged sensor restores normal performance.

01:37A bad ignition coil causes misfires, shaking, or low power, along with the EPC light.

01:46You may also see a flashing check engine light.

01:49Quick fix. Replace the faulty ignition coil and inspect spark plugs.

01:54A weak battery can trigger electrical errors, including the EPC warning.

02:01Slow starting, flickering dashboard lights and random sensor faults are common signs.

02:08Test the battery and replace it if voltage is low.

02:12Avoid accelerating hard.

02:15Safely pull over and restart the car.

02:18Check your brake lights.

02:20Don't drive long distances until a scan is done.

02:23Visit a workshop for a quick OBD diagnosis.

02:28The VW Polo EPC light often comes from throttle body issues,

02:33faulty sensors, brake switch problems, or ignition faults.
