Problems with VW Touran 2008: Black smoke and high fuel consumption

Hi, I had a similar problem with my 2010 VW Passat. I'm definitely not an expert, but I do have a bit of experience with cars. In my case it was the lambda sensor that was faulty and was therefore regulating the mixture incorrectly. I had it repaired at my garage and it cost me 375 euros. Are you sure you don't have an error code? That might help to narrow down the problem. It would also be helpful if you could share more vehicle information. Hope this helps you a bit.

Hey, thanks for your answer and help. My mileage is 328147 km and the last service was recently, everything was still ok. With error code... hmm, I don't have a reader to hand. Should I have it read out in a workshop? And yes, I've also heard about the lambda sensor, so it could well be possible. Thanks again, I'll take your advice and have it checked at the garage.

Yes, reading out the error code at a workshop would be a good idea. That should give you more precise information about what the problem might be. It could actually be the lambda sensor, as in my case, or maybe something else. But don't worry, the guys at the garage should be able to find the problem and fix it. And with your improvement buddy! Keep us posted here in the forum on how it goes. Maybe your experience will help someone else. All the best!

Hey, thanks for the tip. I'll go straight to the garage tomorrow and have the error code read out. Maybe it really is the lambda sensor. I'll keep you posted and share my experience as soon as I know more. Keep your fingers crossed that it's nothing serious and can be fixed quickly. Thanks for the support, guys! You guys are great!
