Volkswagen gti epc light

After restarting the car I got off the freeway ok did notice a loud blowing sound though and got to a gas station, then I disconnected and reconnected the negative battery terminal to reset the system. Since then it hasn't happened again and my car appears to be running completely fine except for one thing: when I give it a lot of gas and volkswagen gti epc light try to accelerate quickly I hear that same loud blowing or sucking noise coming from the engine.

Volkswagen gti epc light

Some of you may recall my request for opinions on a VW Rabbit with the 2. The other day, it is reported that the car was proceeding down the interstate when the engine suddenly quit running and the tach needle went to zero. Driver reportedly shifted to neutral for an uncertain period of time, after which she re-engaged a gear. Car resumed running, but would not go in excess of 70 mph. EPC light was on. Car falls into my possession. My attempt to pull codes yields zero codes. The light has not come back on, and there are no symptoms, other than perhaps a slightly rough idle. Car drives fine. So, what would cause a complete loss of power presumed lack of ignition spark , then go away spontaneously a few seconds later? Just what I need, a diagnostic mystery on an old VW.

I thought I needed a new battery because I have to jump start my car to get it to run if I don't start it every few hours.

Home » Engine. Seeing this can be somewhat alarming, but what does the EPC light really mean? Continue reading to discover more! It means there is a trouble code stored in the EPC system. The Electronic Power Control system is monitored by the engine control unit , brake control unit, transmission control unit, and steering control unit. The most common causes of an EPC light are a faulty throttle body, a faulty ABS sensor, a cracked ABS ring, a bad brake pressure sensor, or a faulty brake pedal switch. It can also be caused by wiring issues or other electrical issues. The throttle body controls how much air should enter the engine when you press the gas pedal. The EPC system uses the throttle body to control the engine power, and if there is an issue with the throttle body, the EPC system will not be able to function properly.

In a few words: The EPC warning light comes on to indicate that there is a problem with the electronic system that controls the engine. You should take into account that the problem may go from a burnt out headlight bulb to throttle failure. For this reason, trying to find the problem any other way may be a troublesome task. In these cases, the throttle will have a TPS Throttle Position Sensor and an actuator electric engine , that is to say, there are no mechanical connections between the throttle and the engine of the car. As a consequence, the EPC is in charge of the regulation of the throttle body according, mainly, to a signal sent by the throttle sensor. This is how fuel consumption and emissions are decreased. This system is also powered by the signals of auxiliary sensors such as the crankshaft position sensor CKP , the manifold absolute pressure MAP sensor, the mass air flow MAF sensor and the knock sensor, among others. This warning light will turn on briefly when you turn the ignition key and then it will turn off, which indicates that the light works properly. If the warning light is still on even after the car has been started or if it comes on while you are driving, that means that there is a problem with the acceleration system. In addition, your car may jerk, have combustion issues or loss of power.
