Tried it back in Sport, but no real power and it revs really slowly. So I think it must be in some sort of protection mode. Post by monkeyhanger » Fri Apr 03, pm.

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.

Many Volkswagen owners have encountered this issue, and, at first glance, it can seem fairly daunting. 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? In essence, it acts as a safeguard mechanism to prevent further damage or even total engine failure. Ignoring it can lead to more serious and costly issues down the line. Some common causes include:. As you can see, there are a variety of reasons why your EPC light may appear. However, one common theme is faulty sensors. If any of the sensors responsible for monitoring engine performance fail, it can trigger the EPC light. Reason: One of the main reasons why sensors can fail is due to wear and tear over time.

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. Post by Nodster » Mon Aug 31, pm Never fedback what the issue was. 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? I called out VW roadside assistance forgot I had that. Let us know. Louder than normal upshift pops? Quick links. Have you changed the stock air filter for some oil soaked one? If it's literally a tenner and can easily be removed and reinstalled, might be better than trying to put it in the garage at this time. Very thorough examination of everything. Related guides. Felt like I'd hit a wall. Post by Chungster » Fri Apr 03, pm. Help Privacy Terms Feedback Publish with us.

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.

Very thorough examination of everything. Search your problem. 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. 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. So I think it must be in some sort of protection mode. It was unscrewed and hanging on the pipe. Have you found an error in this guide? Taking into account that the electronic acceleration system interacts with other systems of the car, it is possible that other warning lights will come on on the dashboard, such as the check engine light or the electronic stability control light , which appear below:. I wonder what has gone wrong. Happy days.
