So apologies, i own a Ford Smax and a Toyota Avensis.  The question is about the Avensis (i hope thats allowed...)

 

Basically my 2011 Toyota Avensis went into limp mode, i limped it to my garage  with white smoke billowing out of it.  My garage stated it was an injector problem and i got one new injector and 3 reconditioned ones.  The problem seemed to go but then i noticed when under load at low revs with foot to the floor in say 2nd or 3rd gear it would pump out a bit of white smoke in the rear view mirrors.

my mechanic felt it could be unburnt fuel in the exhaust that was heating up and going out the exhaust but after 6 months seemed unlkely.

The smoke never appears when in neutral and idling or neutral and revved.  It only appears when up to temperature and under load.

Sent the injectors off again to be tested and all 4 were shown as staying open / faulty, the company gave me 4 reconditioned ones again (under warranty) after they tried to blame contaminated fuel.

 

Changed the fuel filter and put the new injectors in but once again still white smoke under load. My mechanic thinks that its either unburnt fuel in the exhaust or the injectors need to be programmed on the computer which is being done tomorrow.

Im sceptical as to if this will work.

So given the above does anyone have any idea what the problem could be or where i go from here.....

 

Many thanks

Injectors normally are coded to the car

No. they have to be coded every time you swap 1 or more injectors.

 

White smoke indicates water, fuel is black, oil is blue, brown is carbon deposits burning off under load. take it to a different mechanic.

I'm sure that's what Dave meant.

No, white smoke commonly indicates either a coolant leak or simply water vapour, but it can also be fuel vapour.

Get this. Its Techstream. Toyota diagnostic program like Forscan for Ford. Highly recommended by Lexus and Toyota drivers.
