Intermittent P1557 loss of turbo

[CTbora26]

Hi,

I was wondering if anyone can advise on the following:-

I have over the last month or so been experiencing a loss of turbo (usually in 5th or 6th gear and nearly always when engine is cold) and power will come back if I turn the engine off and back on. I have checked the EGR valve for excessive carbon buildup and cleaned (seemed good for a car thats done 102,000 miles) also changed the N75 valve and checked hoses that seemed fine. I am reluctant to take the turbo off and clean, but if its the last option then so be it.

Has anybody had any experience with this that can offer any solutions/advice?

Many thanks

Colin
