Poor fuel economy

Hey guys, I have a strange problem with my 2010 VW Passat gasoline engine. When accelerating, black smoke comes out of the exhaust, the engine runs strangely, the car jerks when accelerating, plus high fuel consumption and the engine light is on. Could it be that the lambda sensor heater is faulty? Do any of you have experience of such a situation or any troubleshooting tips? I would be interested to know how your garage solved the problem. Thanks in advance!

Hi mate, this reminds me of a similar problem I had with my 2008 VW Passat gasoline. It was very similar to yours, only it was the model before yours. I'm not a car specialist or anything, but I have some experience as I generally like dealing with cars. When the car showed these symptoms, I took it to my local garage. The diagnosis turned out to be a faulty engine control unit. It was an expensive fix, costing me 1000 euros! But after that my car worked like a dream again. As advice, you could ask a competent mechanic to check your engine control unit as it could be causing you the same problems. Can you maybe give me more info about your car, mileage, condition of the engine, when was the last oil change etc? This will help us to give you better and more detailed advice.

Hey, thanks for your reply. My Passat has already clocked up a whopping 215785 kilometers, but is actually still running well, except for the current problem. I had the last service about 4 months ago. Everything was fine back then. I'll take your idea on board and have the engine control unit checked. Do you have a recommendation for a good and reliable workshop?

Hello again, it's nice that you wrote back! Your Passat has a lot going for it, respect! But of course, with the number of kilometers you've driven, major problems can occur from time to time. It sounds to me like you've always maintained your car well, which is great. With your last service only 4 months ago, perhaps the engine control unit shouldn't be the problem, but it should still be checked to rule it out definitely. Unfortunately, I can't recommend a garage as I don't know which area you're from. It's always best if you can ask someone in your area. Otherwise, the internet can help: search a few review platforms and read testimonials. And if you're unsure, don't be afraid to ask again here. Good luck anyway!

Hi, thanks for your advice to check the engine control unit. I live near Frankfurt, maybe someone there knows a good workshop. Your tips are very helpful and I will follow your advice and look through reviews on the internet to see if I can find a suitable garage. Thank you very much for your support and kind words, I really appreciate it. I hope to find a solution soon.
