Cleared the codes but the air recirculation just returned after a short play with the control's

I've had a look around some forums and found away to reset the HVAC by going into the basic settings and changing to 001
Now the fault code has changed to:-

-------------------------------------------------------------------------------

00735 - Potentiometer in positioning motor for air recirculation flap (G143)
09-00 - adaption limit surpassed
--------------------------------------------------------------------------------------

If anyone has any info on any of these faults ie: are they common, how to fix, what part and cost etc, please post and let me know
Many Thanks

PS. And where to get cheap parts in the uk from?

Check any boost sensors on the intake side of course & the hvac issues, try testing each feature on the climate & make sure its running when reading it, usually these faults fix themselves & arent an issue

Thanks for you reply
Can i test the intake sensors with vcds? and what am i looking for
in regards to the HVAC, when resetting via the basic settings, there is numbers 12345 and 6. I noticed that numbers 5 and 6 didnt move at all during the test. I think this means a flap or flaps ??? isnt moving at all (can someone confirm this?). 123 and 4 have good movement from about 26 to 220, does that sound normal?

Have you checked in measuring blocks to see if it shows your flaps/sensors names & readings?
