V40 - Diagnosis of fault codes

[JUDGENINJA]

Had the following:
P0103 - powertrain
Mass or Volume air flow Circuit High input

P0420 - powertrain
Catalyst system efficiency below threhhold(bank 1)

P0243 - powertrain
Turbo/Supercharger Wastegate Solenoid "A"

P0171 - Powertrain
System too lean(Bank 1)

P1513 - Powertrain
(Multiple descriptions)

I'm ignoring the CAT issue as it doesn't have a CAT (sssh) and the reference to Bank 1 as it is a generic reader (Torque APP) and therefore might have a setting for V8s etc.

I'm guessing that P0104 is the MAF playing up. I have now fitted it the right way round and have a spare to try.

I'm not sure of the last three...Any ideas??

I think I need to get my AFR gauge fitted.

Airleak somewhere?where is your lambda is it still plugged in Wayne?

[JUDGENINJA]

Both Lambdas should be plugged in still.

Wastegate solenoid would be the TCV, I have a nearly-new one off a S60 2.0T you can have a play with if you like.

I`ve got a S60R that needs plumbing in :)

Thanks, I have a spare TCV to try later.
