Hey guys, I have a 2012 135i and my coolant reservoir is leaking. Anyone replaced or fixed this on their car before? I'm wondering what I should expect the repair cost to be. I would appreciate some replies so I know I'm not getting ripped off. Thanks all.
Is there evidence of leaking on the ground?
It could be internal which is expensive, however it may be at the normal/acceptable level which is not full to the brim!
Also, check for cracks in reservoir, where leaking may occur.
