did you steal a 100PD???

only way to check this is checking the part numbers,,, I use a maf from a PD,,, still don't know which version, it was on a mkIV golf that had N75 and N18 on the bulkhead, so it was either a 115 or an early version 130.
 
it seems at first they shared the same MAF according to ETOS, but later on the ATD engine had a different part number so maybe the non PD wasnt entirely suitable and they had to change.
 
thanks I suppose only way to working it out will be to get both side by side and compare numbers.

havent got it yet but have access to a 100pd passat so hoping to swap over and see if thinsg get better.
