Honda CRV 2.2 CDTi 2008 - Turbo fault? fault code P1236 boost pressure high, done 85K #

Year of Manufacture *: 2008
( Optional ) Engine Code or CC: 2.2 cdti

Hi
We have this vehicle going into limp home mode very occassionally when driving very hard .
DTC P1236 [boost pressure high] .
We suspect the variable vanes sticking within the turbo, it's slightly noisy too. We would take any other advice before removing! The book time for the removal and install is 3 hours which looks pretty tight,Is this possible and is there anything we should watch out for !

TIA

Damian

Hi Damian, use mitivac on turbo actuator to pull some vac on and off, check that the linkage moves smooth as you pull vac and does not stick at any point. I have used Innotec turbo clean kits many times on VAG variable turbos and this has always cured dirty and sticking linkages/vanes, hope this helps,
Paul
