Black smoke and loss of power in Toyota Hiace Diesel 2009: Experience and advice wanted

Hi guys, I drive a 2009 Toyota Hiace Diesel with 218,353 km on the clock. I have recently started having the following problems: When accelerating, black smoke comes out of the exhaust, the check engine light is on, the engine power decreases, the car jerks when accelerating, plus a loud hiss when accelerating, increased fuel consumption, strong exhaust smell and a whistling noise. I suspect that problems with the boost pressure control could be to blame. Have any of you ever experienced similar symptoms and could give me some advice? What was your experience with the workshop in such cases? Are there any tips to avoid nasty surprises at the mechanic? Thanks in advance for your help!

Hi, Ah, that reminds me of the problem I had with my 2006 Toyota Land Cruiser some time ago. It felt similar and you're right, it was actually the boost controller that was electrically faulty. I took the car to the garage because the engine wasn't running properly and the car was jerking and making strange noises when accelerating. They then diagnosed the fault and determined that the boost pressure regulator was the problem. To be honest, it was a serious matter. They had to remove and replace the entire turbo unit because the boost pressure regulator was no longer working properly and this led to increased fuel consumption. As for the black smoke and the whistling, that was also the cause. If I can give you a tip, just go to the garage and have the fault read out. Experience has shown that there's little you can do wrong. The problem with the boost pressure regulator, if that's what it really is, should definitely be rectified so that you don't risk any further damage to the engine compartment. Good luck with that! Hopefully it's not too bad.

Hey, your experience really doesn't sound like fun. And it looks like I'm right in my suspicions about the boost pressure system. I had almost figured that about the garage. Can you remember how deep you had to dig into your pockets for the repairs? And have you had any further problems since then, or was that it for the time being? Thank you very much for your good advice, I will definitely have it checked! Best regards!

Hey, sure, I can remember that. So, I spent €1520 on repairing the boost pressure regulator, which was electrically faulty. That wasn't easy on the wallet, but since then the problem with the deviation in the boost pressure control has been fixed and my car is running like clockwork again. I haven't had any further problems since this repair. And to be honest, it was worth it. It's better to go to the garage once and have the problem fixed by a specialist than to keep driving around with half solutions and run the risk of it getting worse. So, definitely get it checked out so you know what's wrong. Hope you didn't get too scared - cars can be expensive! Best wishes!

Hi, wow, that's quite a lot of money you had to pay. But it's good to know that there were no further problems afterwards. And you're right, it's definitely better to fix it properly and not drive around with half-solutions. You've really helped me, thanks for your input. I'll contact a garage near me and have it checked out. Take care and thanks again!
