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?
