Notice re: Coolant changeover valve
Dear customer,

We are delighted that you have decided to purchase a BMW, ____________________________ Model, and

Vehicle Identification Number: _________________________________

Customer satisfaction is of paramount importance to BMW of North America. To promote this, quality

checks are carried out routinely.

As a result of those efforts, we have become aware that the sealing capacity of some coolant changeover

valves on certain models may be impaired if outside temperatures are low (below approximately -7

degrees Celsius / 19 degrees Fahrenheit) and the vehicle has cooled to very cold temperatures. If issues

arise with your sealing capacity, a very small coolant leakage may occur under certain circumstances,

such as prolonged exposure to temperatures 19 degrees Fahrenheit or lower (for example, overnight

parking outside a garage). If coolant leakage is detected, you will receive a Check Control message in your

vehicle (“Drive. It is possible to continue driving. Must be checked by the Service Partner.”).

In the event that a notice is displayed in your vehicle or you otherwise experience a coolant leakage issue,

please contact an authorized BMW Center immediately for a service appointment to replace the coolant

valve at no charge to you under your BMW New Vehicle Limited Warranty.

For vehicle that do not experience a sealing capacity/coolant leakage issue, during your first regular

service visit, your BMW Service Center will conduct a check to see if any corrective measure is needed.

I confirm that the information above was provided to me:
