Half engine warning light

[greenhorn]

I get a half engine warning light under hard acceleration, with my N54 E90. Warning light goes away after car is restarted. Checked for codes from odb2 and nothing.

I suspect a boost leak, what does the fanatic think ?

Could be heat soak. Did this happen after a long drive?

It was a short drive, about 15 minutes.

Could be a boost leak. There's a few threads on the forum on how to diagnose it. Is the car modified?

The car is still stock. Want to keep the car as stock as possible.

Thinking of putting a charge pipe in. Just got my RB pcv, will install that, not sure if that will help
