Yes so maybe a second hand one would be the option as brand new ones are quite pricey.
With the re map would that work or would it be to far gone now for that to work? It was over a year ago I had some work done to it and I then managed to clear it and was ok for about 5 months and now it’s back and unless I do a long drive on motorways, which I do quite a bit for work, it will just clog up and the light comes up. Then I do the 20 min driving at 2500 rpm and it clears again but this is becoming a pain having to keep doing it.
