Default Re: Turbo surging/cycling

I did have it at the Mercedes dealership for several days where they ran it through their diagnostics, but no codes were found. They also weren't able to determine anything from live data, but I don't know to what extent they did live data monitoring. I have just the scangauge readily available to me, but figured if the dealer isn't coming up with anything then no surprise if my scangauge doesn't either.

Haven't detected any pulsing or roughness at idle. But my detection method was purely by feel.

Haven't check the turbo actuator, I'll give that a look today and check per

Thanks for the quick feedback, I'll give some of those ideas a run through.
