E46 m3 code p0128
Ok so the weather as been gettin colder and my check engine light came on and off a couple of time with the code p0128 witch has to do with the cooling system. The light came on then when off for a wile then came back on and off again an hasent done it sense is this just something the weather might be doing. Coolant leave is fine as well. Is this something thats common or has any one had this happen?
