It's a pre-facelift with the moustache.

Thanks (again!) for the explanation! I already bought the rotor and dizzycap. It was like £15 for the set (from Nippon parts), now I have finally a "made in Japan" part on the Micra haha 
It was never replaced, for that money I didn't doubt because of it's age. It looked like the rotor is worn out and I have removed the oxidation from the contact points but it was corroded.
Anyhow, I'm going to check the valve/idle waxtat tonight. The sensor is much harder for me then for you because I have a LHD car and there is very little room!
About the "datascan" reading, what tool is that? Is it OBDII, because I have a bluetooth stick for that...
