In a few words: The EPC warning light comes on to indicate that there is a problem with the electronic system that vw polo epc 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.

I called out VW roadside assistance forgot I had that. The clunk doesn't sound good - something has gone where it shouldn't during the drive, vw polo epc, and depending on how big the pops werea little normal or a lot abnormal unburnt fuel has got through the engine and ignited in the exhaust.

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. Most throttle bodies today are electric, and if there is a problem with it, it will light up a check engine light and an EPC light on your dashboard. The brake pedal switch or brake light switch is used to know when you press the brake pedal, so the car should activate the brake lights.

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.

Have you changed the stock air filter for some oil soaked one? A new car like that if it has a problem now may as well get it out of the way instead of it happening months or years down the line. Turned the car off and back on but the lights are still there and the issue still remains. Post by stuartrendall » Fri Apr 03, pm It sounds like an easy and relatively cheap fix, I would have done the same in regards to accelerating. Follow us on Facebook. It was unscrewed and hanging on the pipe. Flicked it to M and put my foot down in M3 and it hit 5k rpm and I heard a clunk from the engine bay, car lurched forward and I got some pops from the exhaust. Post by monkeyhanger » Fri Apr 03, pm Sounds like the MAF sensor thinks the car is getting more or less air than it actually is and either getting an implausible value and reverting to limp mode if it does that immediately on the fly, that could be your "thump" - massive engine braking effect from a car that is suddenly starved of fuel at rpm in a low gear.

With a bit of knowledge and some troubleshooting tips, you can quickly find out what caused this warning to appear on your vehicle — and more importantly — how to fix it! First things first, what exactly is the EPC light?

Modern cars do not have this failure since they have better systems installed to their computers. 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.

I've been having this problem for weeks: I start the engine and everything works perfectly but, after driving for a while, suddenly the EPC turns on. How loud were the exhaust pops? It was unscrewed and hanging on the pipe. He said if I hadn't done what I had done we may have never have found it, or worse, it could have blown off whilst going down a motorway etc. Car oil was up to temperature, so I popped it into manual. No noticeable issues.
