Black smoke and loss of power in the 2018 Audi A1 diesel: Possible defect in the lambda sensor heater?Good afternoon, everyone! My 2018 Audi A1 Diesel with 26,318 km mileage is really causing problems at the moment. I'm getting black smoke coming out of the exhaust, the check engine light is on, I can feel a loss of power, the engine is running rough, it jerks when accelerating and the fuel consumption is catastrophic! I think the problem could be a defect in the lambda probe heater. Have any of you ever had similar problems with your car? What was your experience with the garage after something similar happened to you? Unfortunately, I had a bad experience last time and am therefore skeptical. Thanks in advance for your help!

Hi, sure, I totally understand what you mean. I had almost the same problem with my 2015 Audi A4 petrol engine. I was initially told it was probably a problem with the turbocharger. My garage then ran numerous tests until they luckily found out that it was just the lambda sensor heater. In any case, keep your fingers crossed that it's not the turbo, otherwise it will be expensive. Good luck!
