    I think that they are supposed to filter the exhaust gasses and reduce emmissions. Not sure how effective they ever were :confused:

    one line of thought is that they were there to help prevent damage to the cats from the rich / fuel heavy capabilities of the TT. So no cats, no need for AIVs.

     

    I removed mine about 2 years ago on an NA, and it made no difference to the emissions readout at MOT time.

     

    The only difference is to the garage, now got 2 drawers full of pipes and bits.

     

    good luck
