What do these codes mean?

My 07 D3 TDV6 is showing fault codes P0101 and P0191.

Can anyone tell me what they mean or how to find out?

Could possibly be a faulty air flow meter for P0101, or a split/delaminating turbo hose

P0191 relates to fuel pressure, have you had the high pressure fuel pump recall done? It could be the pump starting to fail if it hasnt been done, or they may have left an electrical or fuel connector loose etc. Is it leaking diesel underneath? Thumbs Up My D3 Build Thread

The fuel pump recall was done about three weeks ago. No sign of leaking fuel. How can I diagnose this further?
