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.
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
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
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.
2 if all sensors are working good than check your engine firing sequence,some times happens when sequence was wrong,
3 check your exhaust and carborator tuning pin that creates the batter combination for firing in bore for batter performance & less emitions ,so check is it ok or not than go to your nearest service center that havad certified mechanics,
till you read this you had solve this problem definatly,
