    Acid or Coke?

    The car survived a 700k round trip in limp mode with no issues, after the squirt of Wurth's "miracle in a can".

    The car is now up on the ramps and about to have the DPF removed and manually cleaned. On closer inspection, I see that there's a 90 degree elbow on the exit side, so I won't be able to get the pressure washer directly onto the core.

    So it's going to be a chemical wash of some sort. I have on hand a bottle of brick wash ( hydrochloric acid) and a 2 litre bottle of Coca Cola (phosphoric acid plus sugar). I also have some CT18 truck wash.

    Which to use?

    I would buy a radiator flushing gun one with the rubber bit big enough for the exhaust and power flush it with the truck wash.

    Got the bastard device out. You can see my half arsed previous attempt at wrapping it in header bandage to try and keep more heat in it.

    Tomorrowís task will be to strip it down and weigh it before cleaning.

    If I was more confident with my welding of thin material I would do this. However, Iím not. TIG and lessons are on my bucket list.

    Gave it an initial back flush with the garden hose, got a heap of black crap out of it. Currently baking it in the BBQ to dry it out, as it appears to have soaked up 1.5 litres of water.
