Audi A4 B5 Avant keeps misfiring

Car won't start

Jerking on acceleration

Stalling while idling

Loss of engine power

Check engine light on

Shaking while idling

Poor fuel economy

Unsteady engine

Black smoke from exhaust on acceleration

Hey guys, have you had any experience with problems with the 2014 Audi A4 gasoline engine? My car has some symptoms: black smoke when accelerating, engine light is on, loss of power, rough engine running, jerking when accelerating, won't start, high fuel consumption, stuttering at idle and vibrations at idle. I suspect that a defective ignition coil or misfiring could be the cause. Can you give me some tips on what I should look out for? How did you get this fixed at your garage and what experiences have you had? Any tips will help me. Thank you!

Hello, I had similar problems with my 2012 Audi A3. Well, I'm not really a car expert, but I've had a few experiences. My garage replaced the engine control unit, which was probably defective. It was quite an expensive undertaking, costing me 1000 euros. However, in order to be able to help you more precisely, it would be good if you could send me some more information about your vehicle. Are there any diagnoses already available from a specialist? Greetings!

- Hey, thanks for the info! I haven't had a diagnosis yet, so I'm a bit unsure. My mileage is now at 223456 km - was recently complained about at the service. Quite expensive, your engine control unit ... I hope it's not that expensive for me. Thanks and best regards!

No problem, you're welcome! Yes, it can be expensive, but as I said, that was the case for me. It could be completely different for you. With these symptoms, it could also be the ignition coil, as you suspected. A defective ignition coil can cause all these symptoms. I would recommend that you have your Audi checked by a specialist. And yes, a lot of driving can of course also lead to some problems. My A3 already had a high mileage at the time of the repair. Stay positive, maybe you'll be lucky and it's something less serious. In any case, you should go to the garage as soon as possible before it gets any worse. Good luck and keep us up to date! Greetings back!

Hello, thank you for your advice and support! I also think that I really need to see a specialist now. It's better to pay something now than possibly more later. I hope it really is just the ignition coil and nothing more. But I'll definitely keep looking into other possible causes and then see what the professional has to say. I'll share my experiences here as soon as I know more. Thanks again and have a great day! See you then!

Misfiring can be caused by a number of issues, but a common cause is a faulty spark plug or ignition coil. Start by checking the spark plugs and ignition coils. If they are worn or damaged, they may need to be replaced. If these parts appear to be in good condition, the problem could be more serious, such as a fuel system issue or a problem with the engine control unit. In this case, it's best to have a professional mechanic diagnose the issue to avoid causing further damage.
