2002 VW Polo - EPC Light and Loss of Power

Computers dont show everything. A data stream using a factory scanner wil pinpoint. Go to private shop that has xperienc using it. Car may just need new plug wires and coil..bad burning effects pollution control. Or injection system is off . A tuneup in other areas can help

OD NOT REPLACE THE PEDAL!!!POOR CONNECTION CAUSES THESE FAULTS AND EPC LIGHT ON AND LOSS OF POWER!!REPLACE THE WIRES AT THE PEDAL CONNECTOR.BEWARE THEY MUST NOT BE GOLD PLATED!!

Have the fault codes read and replace faulty sensors

It sounds as if your vehicle may have severe water damage to the engine. The engine sensors on the golf are suseptable to water damage and can result in epc light that you are seeing on your dash, or so i was told by VW. I replaced all the sensors, alternator and the computer on my original engine, but this action didnt fix the problem. So i bit the bullet and replaced the engine, and haven't had a problem since. If you do the labor yourself it can be done as cheap as $4000. I hope this helps mate.

good luck

EPC means Electronic Power Control.

When this light comes on, yopu could have such a sudden power loss.

However, before visiting a workshop for help, do the following basic checks:

No air leak into the intake system.

Ensure that all the electrical socket in the engine management system are well fitted, no loose contacts.

This light can be caused throttle valve malfunction, MAF, brake lights, EVAP , 02 sensor, secondary air pump.

I suggest you visit a competent dealer or independent shop for help. They will scan the EPC and run 'Throttle Body Adaption'. and diagnos the problem. Ask for a garage with a 'Ross Tech VAG-COM' or a ' VW diagnostics scanner.'

please state what year this vehicle is ,52 plate means nothing to me sorry

i lose power with EPC and brake linning warning lights, after break pad service

Check your brake lights.if the bulbs blow this can induce a brake light switch fault,also the switch itself is a very common problem.this will put your EPC light on

The best way to determine the problem is to get the trouble codes read.
The most common issues are the brake switch (actually on your brake pedal) and the MAF (Mass Airflow Sensor). Since you're experiencing a loss of power I would definitely go with the MAF.
If you were having trouble shifting out of park (if you have an auto) I would say brake switch (this switch has been recalled by vw 2x).

Getting the fault codes read would definitely narrow it down, but I'm betting on the MAF.
Please rate/vote! Thanks!

My Polo had a similar problem and the brake light switch at the brake pedal was replaced. Then the computer was reset and the EPC light issue was resolved. It has something to do with the engine management, when sensing the light switsh being activated, retarding the power of the engine.
