Quman12 No, the check engine light does not come on, no misfires so no check codes, only does it if I have to suddenly give it gas other wise it will get up to 90 pretty quick just need to watch the turbo needle in all gears(even in auto).

DrewP Is the check engine light flashing, and setting misfire or knock codes?

Quman12 I have the same issue. Shudders before red line but when I get off the gas its back to normal, other than that it rides smooth. Anyone know what's going on?

Aero 9-5 Manual shudder when reaching red marker on turbo

Hey guys,

Today my car started shuddering under load (pretty much when the turbo hits high yellow/red. It hasn't happened before and not sure what to look for.

Any tips?
