I always refuel at COCO stations in Chandigarh. Highways visits haven't happened in a little while so all legit fuel to the best of my knowledge.

Thanks, will try that. I always refill at BP 21 COCO. After the 2nd DPF issue, refilled at IOC 33 COCO. If going to IOC 28 is what it takes, will do that - it's not COCO though I believe.

Talked to service center guys about adding fuel injector cleaning fluid after a refill and they said I could do that but should only do that at the service center.

Could you share more on the manual regen you're talking about? Pressing the switch never presented an option to regen, it always said not available.

I have not included any additive in the fuel so far. Not sure about the piston ring situation, will bring it up with the service center technician when I go there for the replacement. Yes, I think I will need to take the car out on highways more often, if that is what it takes to keep it healthy. One of the reasons I didn't buy the 4x4 is precisely because of this - to not have to exercise the 4x4 system, low diff, etc. every few days; didn't know then that the same would be required for keeping DPF healthy. Diesels are dead. I'd have gone for a petrol car if the magnitude of the issue was on my radar before the purchase.

The default settings allow manual regeneration only after DPF status bar goes above 4 bars. There is a customized setting that you can enable at the service center. This configuration allows manual regeneration at any time. Toyota recommends doing this before going to high-altitude areas.



In your case, I don't think this will make a difference, because your DPF goes from 3 bars to DPF full immediately ( In just 12 kms as per your images) . That can only be from bad fuel or bad hardware. May be the soot measuring system itself is at fault.

Re: 2021 Toyota Fortuner Legender & Facelift Review

One more hack which I found on the net. After the application of the tint to the Windshield I noticed that the auto headlamps were getting switched on way too frequently. I was looking for ways how the default setting for the light sensors can be adjusted. Manual didnít mention this. I bit of googling helped me. The below video shows how to adjust the sensitivity. I tried the same on my Fortuner and it works like a charm. No more auto switching of headlights unnecessarily.

Re: 2021 Toyota Fortuner Legender & Facelift Review

Got delivery of our Fortuner and Crysta on 25 September.
As compared to our older Fortuner, new one is much more comfortable and Oh boy! the engine. Just wow. I was in eco mode for around 30-40 km and didn't even realise it. This engine's Eco mode seems more powerful than previous engine's Normal mode. Any gripes that I had with previous Fortuner seems to be solved in this version.

It's a keeper, won't be selling this till government forces me to.

So at a couple of service centers here, they mentioned that we could enable via them the option to manually trigger the regen via the button instead of them having to connect the car and doing it. It is called "Custom Regen" and Toyota India also talks about it in their short video Sending the link just in case the service center guys give some excuse.

Am still optimistic about your vehicle and ideally no one should have to take car on highways etc just because it is BS6 diesel. Knowing that it is Aug 2021 vehicle, the Service Center should have changed the redesigned injectors etc. by now considering it is a known issue and it is being performed on cars for past few months + on new cars. What is definitely unknown is if this "fix" by Toyota works long term - hopefully you don't face them.

Tried manual regen many times in these 200 Kms, but always got 'not available' message from the car's system.

Shame on Toyota for not running a voluntary recall on faulty parts that choke the DPF, and not keeping the customers informed on what to expect.

t2k4, I think as padmrajravi said - the issue here is probably within the measurement system - only a faulty sensor there explains your observation. So I have a niggling feeling that these fuel injector replacements are about to be wasted - and be prepared for more issues of the same sort to reccur.

In fact have you asked the service folks why they dont think the soot-measuring-sensor is the cause of the issue as opposed to whatever they have currently assigned blame to? How are they so sure? Have they validated/tested it for normal functioning (in any way)?

You don't need to take the car out on highways for this. Put gearbox in manual mode, and drive in city at 2500 rpm (2nd/3rd gear, maybe 4th) for 15 minutes, that's enough to burn off 1 week worth of deposited soot.

While I suspect there is a faulty part and believe Toyota technicians have done their analysis, quality of diesel is definitely a problem. I see that regen happens at 250-300KM when I fill Xtragreen where as regen happens at 150-200KM with regular diesel. If the issues so far has occured with same diesel in tank, good to clear the diesel in tank, fill diesel from a reputed bunk and give a try.

Congratulations on your purchase! Wish you many more years of happy motoring! Iím in total agreement with you on the eco mode. Just enable iMT with eco mode. Itís a match made in heaven! Keep an eye on the Eco display on the mid when driving. Both the green light as well as the bar available. Kind of gives you a feel of how regined the engine is.

On another side note, the current version of Fortuner comes with lane change indicator function. 3 blinks. Try it out. It was missing in my Gen2 fortuner.

Thanks for your wishes! My Fortuner is Automatic, so no iMT to enable. Lane change indicator was there in my previous one too, but it's missing from my previous gen Innova. Maybe it came with 2016 facelift.

Yes, it wasn't there in Gen2 Fortuner. In fact , for my new Fortuner I have increased the blinks to 6 flashes at the ASC. Find that more practical for visibility.

Re: 2021 Toyota Fortuner Legender & Facelift Review

Took delivery of my Fortuner on the day of Aayudha Pooje.

This car replaces Hexa XTA and the first impressions are great.

I believe the service center is simply going by what they've done in the past for other vehicles in similar situation. They either know to use the scanner to flush the DPF and if the same vehicle comes in one time too many then get the warranty team involved and start the Injection Kit replacement process. They are clueless (tech-wise) as to what's going on & why this is happening. On being asked if this would recur with new injectors, their answer - yes, it's possible.

Diesel in the tank has been from the same BP COCO station for all of 8K KMs on the ODO except for the highway visits.

The first two DPF failures happened with BP COCO fuel. The third one happened with IOC COCO fuel (changed to IOC for the heck of it to see if anything gives). I am by no means an expert in fuel sampling or how the internal combustion takes place across cylinders or how a faulty soot-sensor or a leaky piston could be the culprit, but that's where Toyota needs to step up. Their technicians aren't doing enough to run a root cause analysis. They take the full reading using the scanner, all the data points, send the report to Toyota and get an approval for the next step, which in most cases is Fuel Injection kit replacement.

Does not seem like a fuel issue.
All our cars get refuelled at Sec 33 COCO and have been doing so for years now. So if you are persisting with that pump, I don't think it could be the issue.

Sec 28 is not COCO. Privately owned but with the highest fuel sales in the city, I believe. They don't have the time to mess around with the fuel quality.

Also ensure that those 15 minutes of high rpm driving starts after the engine reaches its normal operating temperature i.e. the temperature needle reaches its full upright position. Driving for 15 minutes at high rpm from cold start will achieve nothing.
