Coolant leak 335d f31
Hi all,
I've come back from 2000 mile round trip to the alps and noticed my breather hose had disintegrated (i'd fixed it twice already), but I also noticed coolant level was lower than when I left. I cannot find any sign of fluid or staining. There's some tarnishing of the oil cooler which has a coolant hose sitting on top of it, but other than that I cannot see anything. I've checked the hose running from the larger coolant hose, across the front of the engine bay and into the coolant reservoir, but other than that I am at a loss. I've had both EGR recalls done. New water pump about a year ago. Any ideas or places that I can dig further? TA |

The rigid plastic coolant pipe above the oil cooler can fail. However this failing usually results in rapid coolant loss.
Do you have a low coolant warning? Any coolant in the oil? The oil cooler gasket can fail too, resulting in either or both the oil and coolant leaking. |

I'll look at the cooler gasket and see if there is any loss. I'll clean it all off and see what happens over the week. |
