Check engine Auris 2010 1.4D

[nielske5001]

Good evening Toyota owners!

I hope someone can help me here. I need a second opinion. I have already 2 years problems with the check engine light on my Toyota Auris 2010 1.4 Diesel (110.000 km). The car drives normal with enough power and suddenly the check engine lights comes on. The power is reduced a lot at the moment the light lights up. The local mechanic says it's a problem with the DPF. But the car drives normal with enough torque and power when the light is off? I can't believe that the DPF is defective. It would also cost me a lot of money to replace the DPF. Sometimes the light goes out after 100-200kms of driving. The mechanic cleared the code several times and then I can drive 500 kms normal again and then the lights comes up again. I was driving 300 kms(120-140km/h) at the  motorway  and suddenly the check engine light came up. I created an ideal opportunity for the DPF to clean/regenerate and then it gave me such an error? I hope someone has some suggestions to solve my problem because the car drive drives very odd with the check engine light on..

 

Thanks in advance!

Best regards

Niels

What are the codes being displayed?

Hi Niels,

Welcome to TOC 🙂

The DPF should really be considered as a consumable at at 110,000K it is certainly into the area where potentially you might expect it to possibly need replacing but yes, as Frosty said it really needs code read.

He didn't tell me. He attached his Bosch Diagnostic computer to the car and he said it was related to the DPF and just cleared the error. But it comes back frequently. I will ask him for the exact code.

Thanks Heidifirst, like I said I will ask the mechanic for the codes. But how is it possible that the car drives normal when the light is off? I would think that with a defunct DPF the car has limited power all the time?

Just clearing the error doesn't sound like a very good fault-finding procedure to me. I would try someone specialised in Toyota or a Toyota dealership (although the latter will just shrug and tell you to replace the DPF).

Another option is to remove the DPF entirely. This might get you into trouble depending on where you live (I'm guessing the Netherlands or Belgium).

My mechanic went with the car to the local Toyota dealer. The Toyota dealer said that the error code was related to the DPF but I still don't know the exact error code... The dealer did 2 times a forced regeneration but he said that it was not guaranteed that the problem was solved with this regeneration. He said when the error shows up again I need to replace the DPF. This is a very costly replacement. My mechanic told me that there also "unofficial" DPF's out there. Is this a possible solution to consider because the official Toyota DPF's are very costly? I think it is still weird that the car drives normal without the error and when the error shows up the power is limited. I still think it is a problem with the computer and/or sensor but I'm not a mechanic 😉

Removing the DPF is not an option because in Belgium at the yearly vehicle inspection they are introducing new methods to detect the removal of the DPF.

As I understand it, the car going into a limp mode for certain errors is mandated by government. This is in order to prevent the driver ignoring failing emission control function and driving on, regardless, allowing the car to pollute excessively.  It is natural to think the car loses power directly because of a fault, but this isn't necessarily so, it is written into ECU code to 'strangle' the problem car. The directive came out around 2001, I think, and became more stringent later.

Just to state the obvious, the DPF collects soot, the regeneration burns the soot into ash.  The ash has a much, much reduced volume compared to the soot, but it has nowhere to go; the DPF is an 'overshoot' filter with deliberate 'dead ends'.  On many cars the ECU will calculate (mathematically) the current weight of ash in the filter, and when the DPF has exceeded the design limit of ash (say ~150,000 miles, depends on driving style etc., etc.?) it will post an error.

The DPFs are not designed to be cleaned/emptied, but many independant companies claim they can clean them out, but the exhaust needs dismantling to do so, if I understand this properly. 

HTH.

This is very good information for everybody.

But since pretty much everything regarding DPF will significantly impact owner's wallet thickness, I still can't recommend anything beyond "get the code!"

I can't imagine going to a service shop to simply get a shrug look and "something with DPF replace it mmmkay". OP needs to get the precise code and to do some actual troubleshooting. There are lots of times where car faults have completely unrelated root causes, just search this very forum.

At this point a Toyota specialist "not necessarily dealership" is the best bet, especially if you can find one with original Toyota diagnostic software, although those usually are private guys taking on private customers.

Hi guys I know it isnt relates, but I have a Auris 1.4 D4D 60 000km and when I press hard on the gas in 4th gear or 5th while below 2000rpm, between 1900 and 2100rpms the car vibrates all over and then from 2100 and above it just goes fine! Do you find it normal it normal guys?
Again sorry if this is not the correct thread

Ideally you would create your own thread.

But to quickly answer to your question, you're lugging your engine. RPMs at which you floor the gas are considered low RPMs, especially for your small engine, and since it's turbocharged, it takes higher RPMs for the turbo to start spinning, so to say.

It's the same vibration you experience when you start rolling from a complete stop and apply little to no gas while releasing the clutch quite quickly. The car struggles which can be felt with vibration.

I encourage you to google the term and look at some youtube videos, but generally speaking lugging the engine is very bad. Not only does the fuel economy decrease, but there's a risk of having huge problems with engine bottom end, which for a car like this would mean an engine replacement.

I have the same. Your shifting indicator will tell you to shift down (arrow down). It's normal.

I've found that I can't drive the 1.4 D4D like I would the larger diesel engines - it simply doesn't have the low-end 'oomph' and I have to shift a little more often.

No, I think you’re missing my point. I’ve driven 1.6tdi and 2.0d and 1.2tdi and the 1.2 for example like all I’ve mentioned, pulls through Any gear at full gas whit out vibrating all over at a specific rpm, it’s the Auris d4d that vibrates at 2000 rpm specifically, and 1900rpm isn’t a low rpm to floor it in 5th gear or 4th

Yes it is. It's even low for my 2.0 diesel in 5th gear.

I have the exact same issue. Also 1.4 d4d engine. Dealer told me it was due to clutch being "unbalanced". Since the car is only 90k advised me to live with it and replace when worn.

2000 rpms is the sweet spot for diesels, never had one vibrating at this rpm before, irrespective of the engine syze.
