    Default Removing or drilling the DPF, cancelling the EGR fauklt codes with a full blanking plate

    I run an Alfa 159 with the same Fiat 1.9L 16v 150HP as the Vauxhall unit.

    Having had problems with the DPF I decided to drill it. I've discovered that yoiui don't need to drill through it from end to end, but only 10mm into the rear end of it in several places to dramatically improve the flow.

    In the end i got carried away and did drill all the way through. The difference in performance between a partial drilling and a fully drilled DPF are small.

    Once you drill all the way through there is the risk of some smoke during a regen, and if yoiu drill through or fit a bypass pipe a DPF regen is pointless.

    I've designed a small device which monitors for and cancels the regen process.

    I also wanted to block my EGR and have successfully added the fault code switch to the same device which cancels the DPF regens.

    All the details of the project are in this webgroup.

    I also have a ready made device (an ex-prototype) for sale on ebay.

    The ability to switch the EGR and DPF activity on and off is useful. I've been using one of these for thousands of miles now and my only regret is not making it sooner

    I will watch for replies here, but if anyone has any questions perhaps the DPF group is the best place for them.
