Do not use aftermarket cap. The rear bellhousing coolant pan will be the next leak if you fail to do this. Summertime is hard on these cooling systems and the 29 PSI of pressure. I have been running the 1.4 bar cap for 6 months in Florida with no issues.
Any updates from people who have switched to the 1.4 bar cap from the 2007 BMW 335i bought directly from the BMW dealership?

Considering replacing the cap on my '08 4.8i X5 now that I've had the new collapsible coolant pipe installed and the coolant flushed.
