Petrol, 2.0 tfsi 211hp. EPC doesn apear every time when i put ignition. It s need to try beteeen 5 and 20-30 time to EPC apear . I noticed that after a longer trip, the EPC no longer appears when I try to restart. and gives me error TPMS, ESP, ABS, gear box and headlight adjustment. I have an error on almost all modules when I scan with VCDS. I'm interested if you experienced something like this, where the problem came from. when the car is started, it runs flawlessly, it doesn't jerk, it doesn't slow me down at speed.

Hey the epc comes on , on my C7 A6. It comes on sometimes when I turn the car on but not every time. Would could it be ? I do feel a slight decrease in power when it is on.

I'm having the exact same issue as you described, mine is a 2014 Audi A4. Took it to a mechanic who said it was the oxygen sensor (also called lambda sensor). Changed the one who was "supposed" to be faulty, only for the light to come ON again about 2 days later. Changed the other sensor (they're 2 lambda sensors), and again, about 2 days later the EPC light came ON again. I'm getting frustrated with this. I'm going to return to them tomorrow and see what they come up with. I'll let you know if I manage to have it sorted out and what they did to sort it out. I haven't taken to my local Audi dealership because they are ridiculously expensive. I once was quoted R32000 (South african Rand) = USD1700, for rear brake calipers, that actually cost R7000 = USD380.

Hello, I recently had a fuel line come off on my car (weird issue) and after reconnecting the line, the epc light is on. Could this turn on simply from air getting into the fuel line/the car failing to start a couple times?

Can bad fuel quality raise epc warning? Im having same with my a5 2012 engine oil consumed very fast

@HonestMechanicChannel 3 ай бұрын

Yes, bad fuel quality can indeed trigger an Electronic Power Control (EPC) warning light on your dashboard because poor fuel can affect the engine's performance and emissions. However, fast oil consumption is typically unrelated to fuel quality and may indicate other issues such as leaks (internal or external), worn piston rings, valve seals, or a problem with the turbocharger. Do you have an OBD scanner?

Been 2 month since i bought my a5 from a friend engine oil was topped up after 2 months ive been unlucky as there was a mixture of diesel in my fuel tank and when i went to a garage he said only 500ml of oil remained in the engine. Could this oil consumption have happened due to the diesel mixed with petrol

With mine if I hard accelerate the EPC light comes on and it shakes bad and misfires, the code I get is for cylinder 2 misfire.. however I can shut the car of and drive fine and the engine doesn’t shake.. it only does this when I put the pedal to the floor. I also replaced that cylinder plug and coil pack and still have the same issue.

@HonestMechanicChannel 2 ай бұрын

Hi, The symptoms you describe suggest there could be an issue beyond just a faulty spark plug or coil pack in cylinder 2. Since replacing these didn't resolve the problem, you might be dealing with fuel delivery issues, a clogged fuel injector, or a more complex electrical or sensor-related problem. Given that the issue occurs under hard acceleration, it could also be related to inadequate fuel pressure or air intake issues. My bet is on a bad fuel injector on that cylinder

@salvatorej.quaglieri7792 2 ай бұрын

@@HonestMechanicChannel ok thank you, I believe it to be a fuel injector as well. It has 112,000 miles.

Hello You can take out the fuel injector from cylinder nr-2 and place that to another cylinder If the error code is on that cylinder then the problem is the fuel injector

I have an Audi s4 b8.5 and was driving home around 75mph. I went to pass a car and didn’t punch it but when my car downshifted is when it threw the code and started to shake. I turned it off and back on and I took it easy home. Any idea on this?

@HonestMechanicChannel 4 ай бұрын

Hi, honestly, it's difficult to determine, but since the code disappeared after turning it off and back on, it might indicate something is starting to fail but hasn't completely gone bad yet, such as the spark plugs. The best approach would be to scan and check the code your S4 stored.

Hello, I have codes p2293, p0343, EPC indication. I checked the camshaft marks, everything is fine. accelerates poorly at low engine speeds, after 2500prm, as if a second wind appears and the car begins to accelerate. Thanks

Hi Piligrim, managed sort it out? these codes can also be caused by the following 1. VVT Solenoid 2. Faulty fuel pressure regulator 3. Clogged fuel filter 4. Malfunctioning camshaft position sensor 5. Wiring issues related to the camshaft position sensor

Thanks a lot. I changed the fuel filter, changed the camshaft sensor, tried the working car, checked the wires, supplied 12 volts to the solenoid, it reacts. ordered another high pressure pump

I had the same thing at first check engine with cylinder miss fire and EPC light I changed fuel injectors and carbon cleaning for the check engine. For EPC I replaced a damaged cable that went to the gas pressure fuel. After that the car felt better but still had EPC going on in the high way. I had done an oil change at home and guessing by lifting the car up it activated the EPC so I did a EPC reset I seen on a website. After that no EPC light hope this helps!
