Hi ... I have read numerous threads but here goes....I have a 2011 d4d avensis.

Car starts and runs perfect but when it gets up on the temp.guage it puts out blue smoke....not all the time though.

No smoke when starting from cold..no smoke when idling  even when it's hot.

Anyone know what's going on?

Local Toyota garage updated the ecu today and seems to have cured the smoke problem.... thank God was a cheap fix

Hi

Am a newbie on here but similar probs with my 2012 Avensis 2.0 d4d (124,000m) over last few weeks.

No smoke on startup but after few hrs on road it starts blowing out white smoke on pulling away in 1st and 2nd gear, bit embarrassing leaving clouds of grey white smoke behind me.

Checked and cleaned EGR and checked injectors and no faults found.

Have read it could be ECU update or 5th injector problem??

Booked into Toyota garage this week, see what they say??

any more info help appreciated as it’s a solid car and was hoping to get a few more years from it.

white smoke could be DPF regenerating (or at least trying). How many miles on the car?

Still the same here with white grey smoke blowing out from accelerating in 1st/ 2nd/ 3rd gears up to 2000 revs. Only happens when been out continuous driving for about 3-4 hours,  so something is blocking up or sticking??

Do the DPF have a life span of so many years and need replacing as could be that it’s not functioning at 100%?.

yes, DPFs have a limited lifespan according to mileage/type of driving/fuel & Oil quality etc. They are classed as consumables.

Some companies claim to be able to clean them though.

Will be checking head gasket to see if that’s gone in few days to narrow it down??
