Ive done abit of searching to find the answers im just wondering what input you all have about it.
The other week I put my new downpipe and decat on the golf and to stop the eml coming on because of the decat I left the post cat sensor out and tucked it in the black box where they connect to the loom. The theory was that its looking for clean air after the cats done its job which obviously wouldnt happen with a decat lol alls good in the sense theres no more eml coming on but im now getting the fault code 16523 which has got something to do with it being slow to react!?!? Any ideas ?
