Turned the car off and back on but the lights are still there and the issue still remains. It was unscrewed and hanging on the pipe.

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.

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.

Tried it back in Sport, but no real power and it revs really slowly. Quick links. The clunk doesn't sound good - something has gone where it shouldn't during the drive, and depending on how big the pops were , a little normal or a lot abnormal unburnt fuel has got through the engine and ignited in the exhaust. Took the dealer 2 goes to decide it was the HPFP and it needed replacing. Louder than normal upshift pops? The severity of the problem and the accompanying symptoms may vary significantly, which is why it is important to scan the car as soon as possible to know its error codes and begin the reparation process. 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. The car is probably in limp mode.

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. Problem solved.

Many Volkswagen owners have encountered this issue, and, at first glance, it can seem fairly daunting.

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. 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.

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. 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. Related guides. All done under warranty luckily.
