Question about Volkswagen Golf

1 Answer

I Have a 2004 Polo Classic 1.6 Petrol. The EPC light came on on the dashboard and the brake lights stopped working. I replaced the brake light switch and the problem still there, I disconnected and reconnected the battery - the problem still there. After about 2 hours with car switched of and keys removed the brake lights came on by itself and will not switch off - any body knows what might be wrong???

The EPC (electronic powertrain control) system deals solely with monitoring the electronic accelerator pedal and moving the throttle body to match positions. Most likely, there is a problem with the accelerator pedal. However this does not explain the brake light situation......sometimes it is due to aftermarket electrical modifications that are added that interfere with the factory wiring and ecu......i would be looking in that dirrection

My Polo Classic 2004 1.6 is misfiring. There is a smell of petrol and the car is not accelerating rapidly.


Check carefully for fuel leak. If it starts well and then gets worse as it warms up, check coolant temp sensor. May be it just smells like fuel because it misses so badly fuel is not being burnt and floods tailpipe. Check spark at plugs with timing light to avoid sparks where fuel may be present. Weak or irratic spark can be coil/module, crank/cam sensor. Remove plugs to see what they look like or which is not firing.

How to replace parklight on polo classic 2006?


i would go to a local trusted garage and have the car scanned. see what dtc codes come up and discuss with the technician.
This may be a sytem glitch which can be cleared or it may indicate a fault.
sure beats guessing or getting a "pals" advise which could be totally wrong and cost you far more.

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

EPC light on my dashboard


Hi Shamiza, I have a Mercedes Diesel Motorhome and I use Bio Diesel, if I don't dilute the fuel with regular diesel a red light comes on EDC (Electronic Diesel Control) I then go into limp mode no more than3,500 rpm this is in case I do damage to high pressure pump. So I am presuming your vehicle is Petrol and possibly requires a service of sorts to the fuel system? Electronic Petrol Control??
It is just a thought and if it were me I would be knocking my Vw dealership for further advice.
I hope this helps

VW POLO-52 plate EPC light on dash


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.
