Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Well, at first I thought it was the water pump, then after couple minutes of research I found out it is a very common issue. A tip if you want to repair this is, don't go to the dealership, go to a show that knows their way around the engine because they will buy a coolant pipe with seals that can be installed in half the time of the OEM BMW pipe that involves taking apart pretty much everything. These easier to install coolant pipes cost around $250 the install will obviously vary by shop.

Coolant return tube leak through engine valley, under intake manifold. Coolant exits through weep-hole in

water pump. Dealership says it is a 35 hour fix they can do in 25 hours but charge for full 35 hours at $120/hr!
