Avensis D4d 2.0 Tr – Slight Loss Of Power, Blowing Black Smoke, Using

Hi all,

I have a 2008 Avensis D4D 2.0 TR with 28500 miles on the clock, the last week or so I’ve noticed a slight loss in power mainly in low gears as far as I can tell… e.g. pulling off while car is moving slowly in second gear power seems to have reduced and when I look in the rear view mirror I see a puff of black smoke.

I’ve dipped the car for oil to find the oil is a ¼ down from the max mark on the dip stick. Now the car is due a full service at 30,000 miles so I’m thinking I’ll send it in nearly and point out all of the above.

Is there anything I should be worried about here do ye guys think? Any one seen this before?

Hi Igor,

Not quite sure what your asking? Do you mean is it jerking if so no only its not as quick to pull off as before.... and its blowing black smoke out the rear as i try to pull off with my boot to the floor.....

any huge vibration when tried to rev under way?

what is going on on 3rd/4th/5th gears?

cheers

No vibrations, as for driving in other gears power seems ok but there is a little more smoke than before but nothing major... cld be just the fact its 1500 miles off a service.... however the oil level kinda worries me... I was driving it hard last weekend for about 3hrs 100MPH at times but still i wouldnt expect a car so new to be burning as much oil

i deem yoou're the first owner

i deem you'd test injectors first.

as to oil consumption -- whether bedding proccess is finished? what MrT said? This car must be still under warranty.

by the way is engine started well? any smoke?

cheers/Igor

Car starts fine with little or no smoke.... would have thought the car wld be well wore in at 28k miles. It was an ex demo model when I got it at 4500 miles

You say you are putting your boot to the floor in second gear at low speeds. What kind of revs are you talking like 1.1-1.4k?

My t180 with a wide open throttle at low revs wouldn't do much and the black smoke is probably a sign of over fueling because it is trying to be loyal to your request for power by injecting a load of fuel that can't be burn't because the turbo doesn't spool up to produce enough air to burn that fuel until 1.8k. Black smoke could just be un-burn't fuel.

The problem could be compounded by old fluids so it might run a bit smoother after your service and it might be wise to do some high load runs (keeping the engine at 3.5k for a while) and see if you can clear out some soot.

As for oil consumption, it is fairly normal to burn oil at that rate.

You know your car so there may be a problem that needs checking out so see how the service guys get on with it.

I would take it in to Toyota for the service and tell them about your worries, also ask them about the engine "Re-map" has it been done at the last service as this can rectify an over fueling problem. Hopefully they changed the air filter at the last service but being in this trade all my life i do know what goes on, if not it will be very dirty by now hence the black smoke.

Sometimes at night with a diesel car the smoke may briefly show up in the headlights of a car behind but in daylight you don't notice it. Like the other post said waiting briefly for the turbo to spool up this is normal from low revs.

When you say 1/4 way down on the dipstick do you mean a 1/4 inch from the top also what was the mileage when you last added oil, Toyota state 1000 kil or 600 mls per ltr of oil used (which i personally think is excessive) after the engine has been "bedded in", but i am quoting from the handbook so it must be correct!?!? My 2.2d4d hasn't used 1/4ltr in the last 1500mls.

Thanks guys for all the comments.... just to answer your question t-spiritpete its 8500 miles since my last oil change and I havent topped it up at all since and yes its a 1/4 down from the max mark on the dip stick.

Whats this engine re-map you mentioned? Sorry kinda new to all this

Just booked it in for a service later in the week will post back here once its serviced hopefully it will sort it.

There have been previous posts on here about the remap and you can look them up but briefly Toyota have modified the program in the ECU which basically controls all of you engine, Toyota say it is to address an over fueling issue whilst the engine is reaching it's normal working temp. This is supposed to reduce carbon build up inside the engine which can lead to trouble later on. I can see the logic in this but others may disagree. I have had mine done and i an happy with it but speak to the Toyota service desk when you book it in.

Your oil situation seems to be very acceptable to me so no worries there then, i always like to keep my oil level on the full mark no matter what car i have as it is also a coolant as well as a lubricant.

Regards Pete.

Hi all,

Had to register to this forum because I have exactly same problems as avensisTR1415 on my 2008 2.0 D-4D Corolla. There are now 44500 kilometers in odometer and the problem started last week.

There are loss of torque in low revs but after 2000 rpm engine pulls normally. It puffs a lot of black smoke just around 2000 rpm but on higher revs the smoke formation is lesser.

I haven´t had it on ECU remap yet but they are doing it on oil change service on next Monday. I also mentioned this smoke / low torque problem and they promised to check it.

I´m very curius to know what they say to avensisTR1415 about this problem so please come and tell us when you have had your car serviced.

Apologize my bad English.

Hi all, Just to update you all on how I got on.... far too many people never come back to post their results:

Dropped the car into the dealer yesterday for its 30k service mentioned to them the very problem in the Original post... picked it up yesterday he told me he did the ECU remap and he cleaned out the EGR valve as it was quite dirty.

As i pulled off from the dealer I could notice the difference right away the car hand much more power in second gear and no sign of smoke from the rear so problem sorted.

Thanks guys for all your help.

Hi mate! Glad you got it sorted out then, great news!

What did they charge for the complete job, hope you don't mind me asking.

Regards Pete.

Im living in the south of ireland it was 225 euro for the 30k mile service details as follows:

- Wheel Balancing

- Oil + Oil Filter change

- Air Filter

- Pollen Filter

- Brake Fluid replaced

- other stuff you'd expect window washer, light levels etc

-ECU remap and EGR valve was not charged as it was done under warranty.

One thing which still bugs me wheel balancing is still a slight bit out, got new R17 tyres a few weeks ago yet to find anyone that can balance them right. Never did any damage to the alloys just since the new tyres went on its a tiny bit out at 70MPH but that bugs me.

Thanks for the reply, the brake fluid change is normally at 20k then 40k etc but maybe it was missed last time. With the wheel balance problem personally i would take it back until they got it right, after all you will have been charged for it, if it was free it's still no excuse for poor workmanship.

:) Glad it got sorted and thanks for concluding the issue, it should help others too

Not sure what distances you do but try to keep the exhaust temps hot enough to prevent soot build up. Don't be afraid to work the engine, don't boot it from low revs, accelerate between max torque, roughly 2k and 2.6k and cruise at 1.5k - 1.8k; i always accelerate quite quickly to get up to speed too, good for economy! Less time spent drinking fuel if you do it quickly. Plus bigger loads, more heat, better economy on shorter journeys. Then take it through the rev range from time to time and maybe once a month run the engine under load at 3.5k or around that for a good few minutes, maybe 10 or so.

If you lug it down low, too low you can get an over rich fuel mixture, normally a lot of soot / un-burn't fuel but having a EGR trapping that and it cloggs right up. If you are a big fan of lugging low and using the rev range between 1k and 2k it will build up for sure. Did you drive a VAG or ford before?
