Tanx ! and so far everything works great ,.done 1800 km now on new oil.
Not even been over 3500 rpm till at least some were over 800 km.
This weekend flush that oil out and put again some new in incl the oil filter.
That will make sure the engine is totally clean now and then give it its first go to 7000 rpm
Only thing that I lost is the green and red economy lights, not you're worst loss

..but what surprised me was the correct functioning of the oil pressure meter in the dash

It was a gamble to put the old 16V censor on the 20V and plug it in,.was not sure it will work.
