I got this code today after a number of times my 2005 s60 d5 is somewhat losing power when trying to accelerate hard in any gear.
6805 Boost Pressure Regulation Incorrect Flow
Intermittent.

Hoping for some help on what to check please.

that is a general code to say the actual flow through the turbo doesn't match what is expected ...
It could be a multitude of things .
first thought is intercooler leaking , any oil around it? Or a split turbo Hose .

Hi Nick, it’s nice to be back here again. I will check the engine around this weekend. It’s doing well now from 1st to 4th gear, but losing power when pushing it hard halfway through the 5th gear. No smoke at all.
