Fault Code Help - Mass Air Flow and Boost Pressure

[LukeRs]

Hi All,

 

Some of you may remember me, but I used to have an Octavia vRS but now have a Seat Leon 2.0 TDI FR PD 170. I have the following faults, but as you guys are so knowledgeable - can you please point me in right direction of presumably what sensors I need?

With those two codes hand in hand id go with a faulty diverter valve, the maf voltage is expected drop then spike when you come off the throttle and the diverter valve lets the boost pressure into the air filter. It won't with a bad diverter valve. Could be wrong though, this is the trouble with online diagnostics, it's all conjecture.
