This is the fault I have been getting for 1.5 years now and cannot figure.
It is driving me crazy and towards getting rid. So sad I know.
Just today after no issue since the morning of my visit to see Mrc, back it came with avengeance.

Fist issue is really really lumpy idle you can hear the surges of the engine 200 rpm to 800 and back, throbbing.
You look at lambdas they are -25 then up then down the engine responds in almost cutting out.

No fault code though!

I have tried to capture this with some of the logs, some of the logs are jut short blips of throttle when the engine is OK ish to show reading variations.

2nd issue the positive deviation only comes after this idling situation, when the car is then driven under gentle conditions immediately after the erratic running.

3rd The car then throws a code, Positive deviation. All is fine in safe mode boost limited to 5 psi, until you clear the error code then the issue comes back,

Please Please can anyone help or share knowledge of this blatant issue, my car is of no value to me whilst broken and can only be getting worse.

No boost leaks I promise. but both lambdas start to show trimming above the norm, then they get higher and off it goes into free fall.

Fitted new fuel pump, regulator, injectors, dv,s, n75 , n249, non return valves off n80, non return valve up to breather spider, Maf, cam belt.
