RS2 with a boost leak . . .

[Error404]

MFTS faults will only cause the ECU to cut boost to spring pressure, I. E. no active boost control, it won't cause limited or partial boost. As I said before no point guessing, pull the fault codes.

This is the normal scenario, the MFTS can
A/ fail and reduce boost
B/ fail and show wrong temp
C/ fail and show overheat sign in dash along with beep noise
D/ a combination of any or all of the above..

I second that.
And switch off the A/C accordingly

I should have updated this. I replaced the MFTS sensor but I am only getting 8-10 PSI.
Could it be a broken wire from the plug?
Also, the plug is looking pretty brittle, can this be purchased separately?

Great to see you got your interractive device map up and running again Dave. Good man!

Nik, in your other thread you mentioned all was OK after trimming vacuum line and installing new DV?
