Engine problems with the Toyota Etios Diesel 2016: black smoke, loss of power and whistling noises

Hey guys, for some time now my 2016 Toyota Etios Diesel with 62,440 km mileage has been having some problems. I get black smoke when accelerating, the check engine light is on continuously and the engine stutters and loses power. Acceleration no longer works properly either, it jerks, makes loud hissing noises and the engine stalls or shudders when idling. I can also hear a whistling noise. I suspect this is due to a malfunction of the boost pressure regulator. I had a bad experience at my last visit to the garage. Now I'm afraid I'll have to go through another odyssey. Have you had similar experiences and could you give me a tip on how best to proceed? Are there any signs that my assumption could be correct? I would be super grateful for your experience and advice!

Hey, of course I know the problem, I had it with my Toyota Corolla 2018 too. It's really annoying when you're so unclear. After my last visit to the workshop, it turned out that the boost pressure regulator was electrically defective - it was really a job for professionals. The symptoms were similar to yours: stuttering, black smoke, the jerking, the engine noises... Everything had to do with the malfunction of the boost pressure regulator. The check engine light was on all the time too. It really wasn't fun, but the problem was fixed and everything has been fine since then. I would advise you to take your car to a garage. A defective boost pressure regulator is not a minor issue that you can solve yourself. I wouldn't fiddle with it myself, that could only make it worse. So, cheer up, take it to the workshop and have it checked out. It's better this way.

Hello, thank you for your reply. It's a real stressful experience to go through all that. Do you happen to remember how much the fun at the garage cost you? And has anything else come up since the repair or is everything running smoothly now?

Hey, yes, I know exactly what you mean. Don't let it discourage you. I had to fork out €1520 to repair the boost pressure regulator, which was electrically defective. The price was pretty steep, but to be honest, it was worth it. Since I had the repair done, the car has been like a new one! No more whistling, no more jerking, no more idling. It was a real relief! So, take a deep breath and off to the garage. Everything will be fine!

Hey, thanks for the encouraging words. It really helps to forget the worries for a bit at the moment. Your positive report gives me hope. It's hard to swallow that it costs so much, but if my car runs smoothly again afterwards, then I'll probably put up with it. It looks like the garage will be my only port of call again. Thanks again for your help. Bye!
