Default XC 70 ?ECU fault

I have a killer failure with 2006 XC70 2.4D AWD Auto. Basically it stalled while driving and won't run since. No faults displayed, my garage hasn't got a clue what's wrong. Its not a starter or an immobiliser or a battery or a fuel pump. The car will start occasionally and will run as long as you are pressing on the accelerator. Once it is released - the car just stalls.

My mechanic says it might be the engine ECU but he is not sure. There are faults coming up with two injectors but they are not actually faulty. He swapped them around and the issue is still there.

Don't know if this is relevant but about two months ago the car was remapped. It has been running without issues until recently. Also it has got stuck in snow (I know, it is ironic with xc70) and I spent about an hour trying to get it out while revving the motor. Otherwise, I cannot even marginally think of what could trigger the problem.

Any constructive thoughts would be much appreciated. Thanks
