I’ve seen this bug occuring with single turbo systems when a yellow intake filter is active. The intake pipe is facing the wrong direction, so the pipe doesn’t connect to the turbo and instead points towards the intercooler.
I just checked this bug on my 2.5 litre 4 cylinder and it occurs on all turbocharged carburetted intakes, and Mechanical fuel injection.
The Mechanical fuel injection also has another issue with intakes, where an NA intake appears when using a throttle per cylinder. The yellow filter remains in place and the intake appears as if the engine did not have a turbo.
