smoking exhaust

[garc91]

Hi all. I'm hoping somebody can point me in the right direction as to sorting my car out. As of late I am noticing smoke coming from exhaust while the car is driving, only happens when the car is at normal running temperature and when I accelerate above 2500rpm on take off from junction/roundabout but also on motorway. its intermittent and is a blue/grey color. Had car at garage and was told it was dirty fuel. changed fuel filter and still no joy. any info will be much appreciated.

Diesel or petrol?

2.0 diesel

If it's not using oil, there's value in making sure the ECU is updated. You can check the version on Toyota-tech.eu using your vin. An article elsewhere here describes using the ECU for poor cold starting, but one of the benefits I found when I did it was a drastic reduction in smoke. Mine was also only doing it while hot, mine is a 2.0 AD engine.

I'll get onto that right away, cheers pal. Mine is the same, only when its hot and more noticeable in urban areas. Doesn't seem to be losing oil. Also forgot to mention the diagnostics showed no errors with injectors and dpf...

If be interested in your findings, as yours is a T27, later model vehicle, the may be differences to the earlier one, but it would be of interest to many on the forum.

Mine was randomly chucking out clouds of blue smoke unfortunately been a costly experience so far. No fault codes or loosing oil but was the dpf causing it.

Only time I got fault codes was when I unplugged the fifth injector it kept showing a p2002 code and was doing it everyday.

So I’ve had a new dpf but yet to drive it because my turbo packed up. Mines a 2007 t180 I’m not sure if anyone can shed some light on this but Toyota changed the bung size on the small pressure pipe to 16mm according to bm catalysts it’s to do with a back pressure problem.

Sorry for the late reply. Update so far...Garage i bought the car from is saying its normal for the car to do this as its common with the 5th injector and that there is no fault with dpf..have the car booked in for an ecu update tomorrow so hoping it fixes the issue
