From what I can tell from my quick Google search, the 200K's conductor plate simply needs a scanner to clear the code—the one I already have. Does anyone else have any confirmation on this? If that's the case, I'm considering getting a Febi replacement because I don't want to put too much money into my 23-year-old car.
So, say goodbye to a couple curse words, hello to £120 for fluid, filter, and gasket, and £200 for the plate.
