Great explanation.

But this bit... hmm... is it true, almost all diesel cars in Msia have no DPF?

Coz if that's really true, it really wouldn't matter which type of diesel owners of the new Sorento use.

Mazdas have DPF , not sure about other , best to assume that if it is launched after euro 5 was introduced , the DPF filter remains installed , there's no need to remove as using euro 5 is perfect for it .

So chances are the Tucson , maybe f30 320d has DPF installed

Not sure about pickups , jaguar , Land Rover and Audi tdi from grey imports

can name any vehicle selling in malaysia need using Euro5?

hoping for Golf GTD /Passat TDI / audi a5 3.0 tdi to come

Mazda 6 2.2 d, Cx5 diesel, Tucson , Sorrento, range rover ,

The mazda skyactiv diesels and some of the grey imports that didn't undergo the "DPF" delete conversion.

Even in europe with euro 6 fuel (and even higher grade "super diesel"), diesel vehicles still have problems with failing DPFs because most drivers aren't educated on how to properly maintain a DPF. Meaning, need a weekly trip with minimum at least 30 minute highway fast driving, and minimal cold starts/short distance driving/frequent start stop traffic conditions.

As from what I read about how some people maintain their DPF (other than what stated), they underwent a process by a company called Ceramax to "wash" the DPF. Costs around 200 pounds for that, big sum for us, but we can at least expect a minimum of (maybe) RM500 if introduced here. The alternative is to replace the DPF set which easily starts from triple the amount of Ceramax.

But most diesel car owners in the europe are fleet/company cars. Their lease terms are around 3-4 years. So usually near the end of the lease, the DPF almost time liao....just nice to renew lease with facelift/new model. Other than those who thinks of keeping long term, no one cares to properly maintain their cars. For most of us here in malaysia who keeps the car longer, with our traffic condition, the DPF also last at tops 5 years (if you're damn lucky). Most likely 3 years on average from those UK drivers with better engine oil, better fuel quality, and better traffic (on average) than us. Mazda Malaysia is actually hiding a ticking time bomb, but the saving grace is that, due to the lower than average compression ratio of the skyactiv diesel (compared to other diesel peers), the soot produced is lesser.

I have not seen an active regen take place so I think our much hotter temperatures will help maintain cleaner dpf , but we will never know until later

Supposedly mazda had a 2.2 diesel on test for 3 years on euro 2 and had no problems which is why they decided to go ahead and introduce it after euro 5 appeared.

It's the same story as egr , catalyzer, and direct injection , everywhere are 50 percent stories of failure and 50 percent never failed. Just bite the bullet and go for it. In the end when petrol particulate filter also appears , the same story continues.

I'll let everyone know in 5 years time , meantime enjoy the cruising at 160 at 2500rpms

Seems good for you so far. There maybe (can't confirm on this, just my speculation) the possibility that bermaz somehow manage to disable the regen totally, but leave the DPF there as it is an extra job/additional parts for them to refit the exhaust without the DPF. In any case, just check your dipstick bi-weekly to monitor any oil sump buildup.

I understand that anyone has a choice for their cars. Just that there is a need for the car makes (in this case, Bermaz) to educate on some unique peculiarities on diesel cars with DPF. Can pretty much presume that DPF is something totally new to us. Well in your case, hope the warranty also covers this.

Yeah, it's great car you have. Nice choice, enjoy the drive

All diesel can work with conventional euro 2m. It does not mean if you use euro 2m it's a direct death to the engine. My group has a owner who shares the same engine as the new sorento and clocked over 300k with mix fuel both euro 5 and 2m. Engine is still strong pushing out close to 600nm and 230hp. So the myth for instant death is debunked.

Running euro 5 means you will provide a cleaner fuel to minimize clogs on high impedance piezo injectors. The engine for sorento, is same as Santa Fe and same as karnival shares the same design of injector where it is non serviceable. You can try to use those ultrasonic cleaners but most people would recommend a full set change which is costly. Again this can be mitigated by using bluechem injector cleaners. Hyundai is offering this product as base cleaner during each service interval.

For dpf, the carbon sludge is subjected to high heat to be burnt off as carbon powder. You don't need to drive on expressway to flush the clogged dpf. Just rev the car at a high rpm and hold for a few seconds. The high velocity will push the debris out.

Lastly EGR do no operate when the engine is on load. So if you're on idle or cruising and using a cleaner fuel, there is much lesser smog being inhaled back. Ultimately you can reflash to delete egr or use the crude way of blanking off the egr from the intake.

To ts, there is nothing to worry about Diesel engine.

Exactly as above , some have failures , some do not , there's no guarantee of what is what

So up to you to decide

Thanks all for the feedback. Very useful information

I like this thread. I'm also curious/interested in diesel vs hybrid vs full EV in terms of FC vs maintenance.

I don't think they disabled regen , heck they didn't even bother to switch tail lamps leaving it one eyed jack reverse lamp ala euro style.

My train of taught is that our weather is so hot , the engine always reaches operating temperature and exhaust gases temperature also always remains high so the brains says well all is good.

It's true there were many cases of oil level increasing in Mazda but mostly due to too many interrupted active regen. Most of them report the car driven very short distance and seldom reaches operating temperature. It happens quite often in winter , summer is from Monday to Thursday one week a year.

To spot an active regen is easy , your instantaneous fuel consumption read out will jump up , start stop disabled and rpm will raise , just let it finish and you're fine.

To be fair almost no salesman ever says anything about the DPF , they don't even know it's there or what is it.

But if there's is no DPF at all even better , you don't have to worry about anything but if it's there also no big deal

Even worse in Sabah, my area not even had any euro 5 diesel station yet, no choice to driving far away from home to Tuaran is the nearest station got euro 5 diesel, the return trip is 140km journey from K. Marudu, just only shell offer euro 5 diesel in Sabah. luckily my pickup tank can fill up to 100 liter diesel from fuel empty warning sign, plus take additional 6 extra 25L plastic tank to refilled it, I can use for 6-8 weeks straight before next refill. It costs me RM520-550 single refill depends on latest fuel price.

I see. It makes sense as our temperature is too hot. I have been in a 1980s Mercedes at -4C - -12C in winter. Need 20 mins just to warm up car until full operating temp. If driving anything below that the car's temp will drop and the car will stall.

My work daily commute is about 20km in stop-start traffic. Only go back to kampung (500+ km) like 3 times a year. Is it advisable for a diesel?

Idle revving does have the same effect as driving the car high speed. But few seconds really enough? What i read and understand was that it takes time to really burn off the crap in the DPF. And hence an extended drive at least once a week is a good practice.

I'm not sure how much is the bluechem solution cost, but i personally used this before on every 5000km, the cost is reasonable :

Ah i see.....

Diesel engines work best at long distance cruises, and where the fuel economy is better than petrol. In stop/start heavy traffic, there is no significant fuel economy advantages against petrol. And further, there are no small diesel cars in malaysia market, further disadvantaging the fuel economy factor.

If it is the car you like, no harm getting it despite being diesel engined. But if you choose it mainly because of the fuel economy factor, you'll be kind of disappointed with your driving condition.

I see. Thanks. The reason why I am interested in the Sorento is the emergency 3rd row seats. X-trail kind of basic, and does not seem premium. Santa Fe not as big as Sorento. Not interested in MPV looks even though MPV's are big. Not going to using the 3rd row all the time.

Not sure I want to get a 2.4L petrol powered Sorento. Cannot imagine the FC.

Mazda takes longer probably because of all aluminium engine , block and head. For me it takes 20 minutes tp reach operating temp here in Malaysia itself if I get stuck in stop and go traffic add the fact that water temperature is always warmer than oil temperatures, actual engine temperature takes even longer to reach.

It depends on what you want, for me I do 28 km daily only and only one balik kampung trip but I anyways bought the most expensive model possible just because I like diesel and I like torque , but now I find myself looking to do more trips because the car is so capable at long distance cruising , i probably don't need to have spent the extra 10k over the 2.5 but done is done and no turning back

For that range of cars, (bar the grand carnival) the Sorento is the largest of 3 rows SUVs in that price range.

My family owned the sorento equivalent santa fe diesel (albeit previous generation, which actually has slightly larger interior space than the current one), the NVH is half a notch better than counterparts. Car feels rather planted even i reached 170km/h. The new Sorento should have a step up on NVH further.

You can have a perspective from a car blogger here regarding the sorento diesel :
http://kensomuse.com/blog/2017/02/06/new-k...ence-inspiring/

Just that if you get the low spec diesel, the last row has now air conditioning vents like the high spec version.

The HS has the second row curtains, which are quite handy.

When you're driving in jam there is enough heat there to burn. Driving on expressway normally on cruise speed is low rev. That is not enough velocity to formally flush out the debris.

Never tried other cleaner. Sticking to recommended ones. So far so good.
