Bonding Agent Best Before Date:

WARNING: This page is about a different car, the 2003 BMW X5, 2002 BMW X5, 2001 BMW X5, and 2000 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

Repair kit and bonding agent are marked with a date (Best before).

The bonding agent may only be used up to this date (if not already opened previously).
Once it has been opened (locking ring broken), use for 1 week only even if the Best before date has not been reached.

NOTE: Write the date on the bottle when opening the bonding agent for the first time.
Close the bottle immediately after extracting the bonding agent (reaction with air).
