Hi skyman

Disconnect the MAF - Mass AirFlow sensor and report back if the problem has changed and if so, in what way.

Thanks. That should rule out a dirty or malfunctioning MAF.

Next step would be to read codes using a lexia reader. You can find them here on Amazon.

If you don't read the codes, then my first guess would be the turbo electrovalve giving problems, there is some information in this topic (here).

This topic (here) has some screen shots of what lexia can show for turbo faults.
