Default Have you done anything different to the car as of late?

You'l need to vag it to check what codes may hev put you there. Unplugging the ECU and resetting it is the easy way out, but if you have a real problem you'll only go into limp again.

Default Disconnect the negative lead on the battery for 2 - 3 minutes.

That should reset you and get you out of limp. You have a large vacuum leak venting the MBC to atmosphere. Not good. The car will go back into limp mode if you don't fix that problem.
