Avensis 2.0 d4d Tr 2012 excessive white smoke problem

[BigGavensisd4d]

Hi there

Have read through some archives on the forum about this subject but no definitive answers AFAIK??

I use my 2012 d4d tourer as taxi and have now 125,000miles on clock. Great car apart from this recent annoying problem am having!!

Have over the last 3/4 weeks had excessive white gray smoke upon accelerating in 1st / 2nd and 3rd gears ( up to 2000 revs) after the car has been on the road for a few hours and at operating temp.

Been down the routes of adding fuel cleaner to the fuel,tank....Cataclean, Cleaned the EGR out and replaced all filters inc fuel filter.

 DPF and pressure is fine and checked all injectors at fuel injection specialist...no faults shown.

Car was Terracleaned last week with a standard carbon clean....improved slightly and had no smoke for 1 day then back to usual white smoke again in the afternoon, with clouds of while smoke covering the car behind me....bit embarrassing really!!

Just been to local Toyota dealer and had expensive diagnostic check; EGR and DPF not blocked and latest ECU software is up to date too,  no faults shown.

Getting frustrated as still no clue as to what’s causing this?? Seal or pipe leaking somewhere possibly?? EGR not functioning well?? Turbo seals leaking??

Anyone else had this issue and resolved it??

Any help or info much appreciated as tearing my hair out with this??

White smoke? Broken head gasket? Water in the oil?
