On my CX5 2016 2.2 diesel. I VMF light came on my dash, had to get the vaccum pump change. On the motorway engine oil red and check engine amber displayed. The car was driving normal. Once I reached my destination got it diagnosed at Mazda, low oil pressure. Got the strainer changed, injector seal changed to a new one, camshaft didn’t had carbon build up, also got engine flushed and then fresh oil and filter. The pressure parameters was normal during the live test. Drove 100 miles first time saw coolant spray on my engine. This happened once and the same fault code P055F came up. Puzzled now on what to do now. The garage is suggesting next level of elimination to now change the oil pump. Can anyone with similar experience suggest the next line of possible diagnostic. The car is driving normal as earlier. Is there a sensor issue?? Don’t know.. have got drained enough now financially
