COOLANT POURS OUT

I have had to replace my coolant almost every after 2 weeks, before i drive i have to top up the resevoir with water.

The coolant pours out when i stop the engine.
Check coolant level displays
When in heavy traffic, temperatures rise and go down when on high way.

Any help is much appreciated.

The M271 is known for having the plastic/composite coolant pipes cracking. There are 4 pipes in total (that I know of). Changing out all 4 is recommended, as 3 of the 4 in my car broke within 3 months of each other.

More information can be found here. Good luck.
