Hi VFX,
I am the newish owner of 2005 987 3.2 and would like to know if you got this sorted?
Was it a catalyst issue that meant a replacement?
Do you happen to know what the error code is for BANK 2?
I have been to 2 garages and i forgot to ask as my motor generated a CEL and i have no scanner but both have said Cat issue and need replacement, but the car seems to be driving fine.
