Ok I stand corrected the later engines can be effected.
The results from your oil tests show that if you stop the egr working and change the oil you get better results. The aluminium and silicone is still there but at lower levels and and maybe another oil change might reduce that further.
I guess the question to ask is deleting the egr valve control software legal but then is the system causing unnecessary wear on these engines.
