SUBJECT:
New DOT 4 ESL Brake Fluid
MODEL:
All
SITUATION:
The DSC pre-pump has been deleted on the new X5 4.6is, and will also be deleted on future models.
This new configuration requires a lower viscosity brake fluid in cold weather applications, which is satisfied by using DOT 4 ESL brake fluid. DOT 4 ESL fluid can be used in all vehicles that require DOT 4 fluid; however, regular DOT 4 fluid must not be used to top up the X5 4.6is as it will reduce the low temperature properties of the DOT 4 ESL fluid.
There is no change to the brake fluid maintenance interval on vehicles equipped with DOT 4 ESL fluid.
PARTS INFORMATION
DOT 4 ESL brake fluid is available under the BMW part numbers are shown.
