insignia b 2.0 CDTI OIL PROBLEM

[klaudijus]

hello, need some help. Car i have is Insignia b, 2018, 2.0CDTI 125kw. I'm having problem with engine oil pressure control solenoid valve and engine oil pressure sensor. Check engine light comes up once in a while and goes into the limp mode with CEL on.  The faults i have- p0521-00, p06DE-00. Both sensor and solenoid are already changed, oil pressure OK, oil level OK. What else could cause these fault codes?

usually the replacement sensors and valves sort this issue, would be good to ensure that the codes have been deleted from memory and also the oil quality has been reset - even an oil and filter change if it hasn't had one would help I'm sure?
