Problems with VW Scirocco 2014: Black smoke, loss of power and difficulty starting

Hey, I once had a similar problem with my 2012 VW Golf. It sounds to me like a defect in the fuel pressure regulator, which I also had at the time. FYI: I already have some experience with cars, but I'm not a professional. In my case, the repair was pretty simple, I went to my regular garage and they were able to find the fault quickly. However, it cost 250 euros because the whole fuel pressure regulator had to be replaced. Something valuable that I learned during this time is that it is important to recognize the earliest signs of car problems. Ultimately, it can save time and money. But to help you more accurately, it's important to know if you've made any modifications to your car? And have you already read a fault memory? Believe me, this could help to better understand your situation.

Hi, thanks for the quick reply! I haven't actually changed anything on my Scirocco, everything is still original, and the last time I was at the garage was a while ago. I haven't read out the fault memory yet, that's a really good idea, I could have figured it out myself! My mileage is 88056 km, if that's important. I hope it won't be too expensive. I guess I really should get it to the garage as soon as possible. Thanks for the tip about the fuel pressure regulator, that makes sense!

Hey, all right! An unchanged car is already good, so you can rule out some problems. Reading out the fault memory is always recommended, and with your mileage it could actually be the fuel pressure regulator. Problems can sometimes show up there. If I were you, I would really visit the garage. Sure, it might cost a bit of money, but better safe than sorry, right? And in the end, it's always cheaper if you recognize a defect early and fix it than if you wait and it gets worse. To be honest, it wasn't cheap with my Golf at the time, but I told myself it was better to invest properly once and then I'd have peace of mind. And it was worth it, after that everything ran like clockwork again. Keep your fingers crossed that it's nothing worse and that the costs are kept within limits. See you around!

Hey, thanks for your tips and opinions. That's exactly how I'm going to go about it. Read out the fault memory and then off to the workshop. The motto now is: "Eyes closed and through!" It's probably true about recognizing and rectifying defects at an early stage. It's better to take precautions than to make up for it. Even if it hurts your wallet at first. I'm keeping my fingers crossed that it won't be too bad and expensive. Thanks again! See you then!

I think it comes from the lambda probe, is it easy to change by myself?

(Translated from French)

It's possible that a faulty lambda (O2) sensor could cause some of the issues you're experiencing. However, changing it yourself depends on your comfort level with car repairs. It's not overly complex but does require some tools and knowledge. You'll need a special O2 sensor socket to remove the old sensor and install the new one. Remember to disconnect the battery before starting. If you're not comfortable doing this, I'd recommend taking it to a professional. Please let us know how it goes or if you have any other questions.
