Hello. I was wondering if anyone out there could help me . I took my X5 diesel into the local bmw dealer because I was having acceleration issues leaving stop signs . They’re telling me the issue is my exhaust cooler . So I mentioned that I had an EGR cooler replaced last year under recall. They have told me that this is a different exhaust cooler near the intake ? I cannot find pictures or info on this 2nd cooler anywhere. Does anyone know about this?
