On my 2014 6105D I get two codes: ECU 101.00 and ECU 101.16. I do not have them in my manual but I found them on-line. The first one means "Crankcase pressure high. Engine power limited. Check blow-by filter" and the second code means "Crankcase pressure high. Check blow-by filter".
I am not aware of having a blow-by filter on my 2014 6105D tractor. Is there one?
