Toyota Auris Touring Sports - DPF Issue - EML AUris - Harry TT

Hi All , I have a 2014 Auris estate 1.4 Diesel...The Engine light has come on. Got it checked by a mechanic who said it's the DPF and advised to run it hard on the motorway.

(I've noticed much lower MPG and the start stop doesnt work since the light has come on)

I also bought a few bottles of Wynn's DPF cleaner and have tried to do the regen on the motorway but the light is still on.

I have also read online that for the regen to occur, the EML light shouldn't be on? Is this true because if it is then I've just been wasting my time trying to get the regen to occur on the motorway.

Also, I'm not sure if the dash has a DPF light but if it does, why hasn't that come on instead of the engine light.

Thanks

Drive it hard and fast where legal for at least 30 minutes in 3rd gear (motorway blast), then keep it idling for another 15 minutes. What is the mileage?

That will achieve nothing whatsoever. On a modern car all the driver does is make inputs into the Engine Control Module. The ECM decides how to run the engine, and when to initiate the DPF regeneration process. If it does not regenerate then it looks like the OP will be taking a trip to his Toyota dealer.

This is exactly the reason why people are now being advised away from diesels, and more especially if the bulk of your driving is short journeys in which case this problem will happen.

These come with a 5yr 100k manufacturer warranty from new which does cover everything even the DPF if the car has been used correctly and serviced by a Toyota dealer. I’m assuming it has done a big mileage?

I have tried revving it on the motorway at 3000 RPM for half an hour but the light still hasn't disappeared. I have also used Wynns Black DPF cleaner on a full tank. The mileage is 97K but it hasn't been serviced by Toyota since 65K miles.

Thanks for your responses. I will try doing the motorway again on 3rd gear for half an hour. cheers

Quite possibly the DPF is blocked. Which means getting it properly cleaned by the 'ceramex' method or a new DPF.

At almost 100,000 very likely to be a full DPF.

Clean or replace time.

Driving with too many revs is more likely to prevent a regen than assisting one. Fact is the DPF needs to be at 600 degrees or more for a regen to take place and with too many revs the exhaust gas speed is to high to heat up the matrix. Your handbook will tell you the correct revs, on our Kia and BMW it was advised that between 1800 and 2000 rpm were best but obviously other makes may be different. The car ECU controls the regen and not your speed.

On fact that is the same for all brands, stationary at idle and the regen will stop.

Oil of the smake. You have wasted your money.

Drive up long (1 mile+) hills at 40-50mph. Heats engine and exhaust up - very quickly.

Just thought i'd chuck this in here, maybe if enough people demand this type of system on cars and refuse to buy until the maker's do, they might just oblige...

On some of our lorries via the menu you can see on the display the state of the DPF and if necessary start a regen (this make i don't drive regularly so don't know if it's a moving regen or not).

On the new lorry i drive regularly, it will tell you if a regen is required, but you can ask via the menu as well and it will either say 'regen not needed' or if it does require a manual regen the driver's manual says to park in a suitable place (obviously keeping in mind where the exhaust is and where it points) and select regen via the menu.

Now wouldn't something along those lines be much easier for most car owners, you're just setting off on a long journey, so you select dpf on the display and find it needs a regen fairly soon, what better than to be able to perform that regen at the ideal convenient time for both the car and its owner/driver, that's got to be better than the present hit and miss secrecy involved where you haven't a clue what the state of things are on a product you actually own.

I discussed this with the service manager at the Kia dealer back in 2010 after we had bought the Ceed, I asked why there was not a a warning light on the dash telling you when a regen was taking place so that you could avoid stopping until it had finished (and the light went out).

Answer was simple, chap said it was a question that had been raised at various meetings but in truth very few owners acknowledge warning lights and read manuals so why bother.

After a few months it was not an issue for us, we could tell by the siund of the engine and and even the way it responded whan a regen was taking place. For almost 5 years we never missed one (but on occations we still had to stop during one - impossible to carry on driving sometimes).

It does heat it up a bit more than normal but not up to 600 degrees. But if a regen is not needed it will not start one, only the ECU will do that, not a 1 mile hill.

A website has the following recommendations before bringing it to them for a DPF cleanse

1. Make sure that the Engine Management Light is not on and that there is at least a quarter of a tank of fuel.

Which is why I am worries. As the EML is on, im not sure if it will let the regen occur :/

I don't accept their reasoning, and i doubt you do either.

Its another example of lowest common denominator think, because someone clueless buys our vehicles we assume everyone who buys one of our vehicles is as clueless, i cannot stand this modern think.

It would cost pennies i suspect to make information and manual triggering available on the dash, by all means make the display hidden for the plant pot who finds checking the engine oil level too mentally taxing, but as is the case in so many things these days because Clueless can't, they assume no one can.

Lowest Common Denominator think is killing this country.

Nothing to do with this country is it. Cars are made pretty much the same for all markets with the exception of specific extras that are a must in some. But those extras are, to give examples easy to fit ones such as tinted rear windows and parking sensors. Changing the ECU programming especially for the "idiots" in the UK who cannot be bothered to read the manual is pointless. And lets be honest, the UK does not have the international maket in "lowest common denominator" does it, just take the the US president as an example.

Even supposedly clever people don't have a clue. Company I worked at many years ago had a company car policy that basically said that the cost of repairing any damage inflicted through lack of care or missuse would be deducted from the persons wages, seemed fair enough to me. But one director took the urine. He was a serial member of "running the tank dry club", no idea what a fuel gauge was for. Had a new company car and the fleet manager ordered it specially with built in sat nav and set it to show filling stations. Car was delivered to the office and on his way home he drove past 4 filling stations before he ran out despite the fuel light being on and the gauge saying zero.

Before it got to 10,000 miles he had run it dry of oil which did serious damage to the engine. Doubt they deducted a penny from his salary. When I left he had just got his first diesel which being 2011 would have had a DPF, wonder how he got on with that one.

On many modern diesels you can run the dpf regen with a diagnostic unit which unless you wish to purchase your own would mean a visit to a garage.any will do as long as their diagnostics will run the dpf regen program on your car.if it is blocked solid it may need replacement or professional cleaning.(possible terra clean if you have an agent in your area).
