Yellow engine warning light loss of all power

Just after a few thoughts. I've started to have the yellow engine warning light come on a on a 2007 220d when going above 2000 revs ( almost instantly above 3500 ).

It results in full loss of power.

Removal of key for 10 seconds and a very bouncy restart gets power back.

Garage is thinking a faulty injector as error codes all check out fine etc...

Any input?

are they using a bmw scan tool a half engine light (limp mode) should usually give you a quite clear engine code

Yes they did it came back with a filter error which was replaced but still getting the same code.

They are suspecting a bad injector as apparently this doesn't put out a code? But will cause the engine to stall / loose power

sounds like the right diagnosis if the injector is clogged or faulty and the air/fuel is to lean, the engine wont make enough compression to keep the engine running.
