SE it sounds european to me , rough guess UK... which did have nikasil blocks in the M52 528 motor up till 1998 and definitely was a problem in some cases. I would suggest you dig deeper into the car to find out if it is a nikasil motor or not. There is a fair amount of info on the net concerning m52 single vanos nikasil motors such as here
