As far as I'm aware the engine is still ok, nothing feels out of the ordinary; yet. Am very much hoping that nothing has been damaged, but Romain said that running the car for such a short period of time shouldn't have caused anything.
Edit - after seeing RM CYA's post.
The EML came on on the train heading in to France prior to the trip, I kept it out of vtec for about 90 minutes to 2 hours wondering why it was there. It disappeared then came back, but the car seemed to drive the same. Obviously not having a laptop with software etc available I wasn't able to know what the issue was. So I just drove the car as normal for the trip, and then got it seen to as soon as I returned to the UK. Best I could have done considering. It only started failing to engage vtec the day before I took it to Romain (after only having driven it once after the trip).
