2005 Rav4 D4D Turbo Issue

[JZA80]

I have a 2005 Rav4 D4D that has developed an intermittent turbo problem. Pull away in 1st gear and the turbo almost always comes in and it accelerates normally, change up through the gears though and more often than not the turbo doesn't kick in. It is very random though you can be driving along with no turbo boost, then it'll suddenly come in and accelerates, then it'll suddenly stop boosting again.

I've checked all the IC hoses, vacuum lines and can't see anything obvious, there are no dash warning lights but I haven't had it checked for fault codes yet.

Any ideas and help would be much appreciated.

I'm a big fan of running a cleaner like this through the intake system:

Wynn's Egr3 Intake System Cleaner Diesel

Then driving it like I stole it for 5-10 miles. Diesel engines clog up really easily, if not given a good old blast every now and then.

Good shout! Sprayed a couple of bottles through the system whilst idling and it's completely cured the turbo issue.

Cheers for the suggestion.
