About as off topic as they come, this...
The engine management light on my xtrail came on the other day. I have been driving the car since and noticed no performance issues whatsoever, including a trip to the in laws where the engine would have had a good blast and any flat spots or underperforming would have been noticeable. I bit the bullet today and took it to a local garage for a diagnostic. The verdict was the EGR valve.
Anyway, they've cancelled the fault code and the light has gone out. I know a very competent diesel specialist who works for beer money so the car will be going to him for any work.
My daft question is this: How long does the cancellation last before the light comes back on, and if the light doesn't come back does that suggest some kind of glitch as the initial cause rather than a genuine parts fault?
