Persistent problems with Toyota Yaris Diesel 2015: Pre-glow light, high consumption and black smoke

TOYOTA

Yaris

| 2015 | | Diesel

Longer cold start time

Check engine light on

DPF regeneration failure

Pre-glow light won't turn off

Car won't start

Black smoke from exhaust on acceleration

Poor fuel economy

Hello folks! My 2015 Toyota Yaris Diesel with around 73,000 KM is experiencing strange problems. The preglow light stays on constantly, black smoke comes out of the exhaust when accelerating, the engine starts poorly and consumes more fuel than usual. The check engine light also won't go out and my car occasionally won't start at all. There seems to be a problem with the DPF regeneration. It occurred to me that a glow plug might be faulty? Do any of you have experience with similar symptoms and know what exactly the problem could be? And what was your experience of having this problem fixed by a mechanic? Because unfortunately I've had some bad experiences in the past. Thanks in advance!

Hey, I had a similar problem with my 2012 Toyota Auris Diesel. It was getting harder and harder to start and the engine light was on all the time. I had the same suspicion that a glow plug was broken, due to wear and tear. In the end, my assumption was correct. At the car service center, they determined that not just one, but all of the glow plugs needed to be replaced. The problem was serious because defective glow plugs lead to starting problems that could damage the engine and other parts. That's why the mechanic pressed for an immediate repair. I can well understand that you are worried because you have had bad experiences, but in my case everything was well organized and the repair was carried out professionally. So my advice: don't put it off, go to a garage you trust and have it checked. If it really is the glow plugs, replace them. It's a worthwhile investment in the longevity of your car and in your peace of mind. All the best!

Hey, that doesn't sound great, what happened to your Auris. But it's good to know that in the end it was just the glow plugs. Can you remember how much the whole thing cost? And have you had any problems since then or is your car now running smoothly again?

Hey, yes, after that everything was back to normal for me. After the mechanic fixed the problem with the glow plug, my Auris ran like clockwork again and I had no more problems. And as for the cost: the repair cost me €560. That's not a lot of money, but in my opinion it was a worthwhile investment for the glow plug, which was defective due to wear. My Auris is now purring like a kitten again and there are no more strange symptoms. Hope this helps you. All the best!

Thanks for your quick reply. 560€ sounds like a lot at first, but when I think about it, it's an investment that will pay off for the longevity of my car. It's always good to know what to expect and the fact that your Auris is now running smoothly again gives me some peace of mind. I'll visit the garage tomorrow and hope for such a positive result. I feel a bit better about the whole thing now. Thanks again for your help and I hope your Auris continues to run smoothly. All the best!
