Noticed an anti-freeze smell and when I popped the hood I saw antifreeze bubbling from the center of the bleed screw, how it came to have a hole in the center I have no idea. What are my options on this? does anyone know the thread size and if I could find a brass plug or something to thread in there?
thanks

 

There's a brass replacement you can purchase at the BMW dealership and the parts guy usually knows what you're talking about or you can scoop it up on eBay if you don't need the vehicle for a few days.

 

Thanks, Do you know what the part number is?

 

Somebody over tightened your bleeder screw. It is a common issue. Stick with the plastic screw, it is much easier and less expensive to change the screw, rather than changing out the combo hose with the t-fitting. If you overtighten the brass screw, it will break or strip out the t-fitting and then things get expensive. The plastic screws are about $4 each, buy two or three and keep the extras in the coin drawer in the dash to the side of the ac controls. Make sure that you bleed the system when you get the new screw. Good luck. Phil

Here is the link to the part, but I paid half this, so I'm sure you can find it cheaper.

Thanks for the replys. I have had the screw out a few times while bleeding system from water pump change. The weird thing it's bubbling from the very center of the screw.

 

mine did the same thing with two different bleed screws. The center area seems to be the week spot on the design. Good luck. Phil

 

Is the plastic bleed screw replacement a dealer only part?

 

It's a dealer part that you have to buy the housing to get or you can get the screw seperatly from a BMW dealer.

 

You have to buy the entire T assembly in order to get the screw from why I gather when i had the same issue.
