A few quick questions:
1. After clearing fault codes, how long (approx) before they can re-appear, if normal driving is resumed immediately?
2. Can fault codes sometimes appear by mistake? Please give examples.
3. Do you have any other strange experiences with fault codes that you'd like to share?
I'd like this to be a general discussion on the topic of fault codes and your experiences with them.
I've recently had a 'strange' experience myself, and I will write it down in due course.
