If light on during ignition = ECU logged fault but no fault present anymore.
If light on during running = ECU logged fault that's still present.
Now, I had this icon recently, following disconnects and work to Air Filter/Box, Boost Sensor, EGR Valve and Throttle Body. Initially my icon was on all the time but no Fault was logged in the ECU. It turned out the a plug (perhaps all) was not re-connected correctly. The Icon is now only present during ignition, which will clear itself after 'some time'.
Back to your problem; last year I started getting the usual EGR & Boost Sensor issues that plague CDTI models. It manifested itself initially in exactly the same way as you describe. Basically going into Limp Mode periodically, until one day it got stuck there. I put this down to a partial cease of the EGR Solenoid Pin turning into a full cease. Point being no fault code was stored in my ECU until it failed completely. I stripped and cleaned the EGR (and solenoid + pin) and boost sensor and the problem was fixed.
As for your 'Air Hiss' I get this too under the same conditions but I always thought it was a valve on the turbo system. I usually hear it when quickly changing up the gears down our country lanes (rebound of the hedges), in most instances my revs are 2k plus when changing.
2006 CDTi 120bhp BTW
Apologies if this has nothing to do with your issue.
