BMW Brake Warning on the iDrive: All Four Corners Renewed Plus a Full Service

The BMW's iDrive screen lit up with two alerts: 'Brake system. Drive moderately' and a separate indicator for rear brake pads. On a BMW, an electronic brake wear sensor is embedded in the brake pad and triggers as the pad material wears down to its service limit.

The owner had been in for a wiper replacement a few weeks earlier; the iDrive warning followed a few weeks after that, which prompted the return visit.

The ask was clear: inspect all four corners, replace whatever needed replacing, and sort the car properly so the warning would clear and the brakes would be reliable again.

We pulled all four wheels and inspected the pads and discs front and rear. The front pads were also due, so both axles were done in the same visit.

The discs front and rear were worn and due for renewal with the pads. Replacing pads on discs at the end of their life means the fresh pads bed in against worn surfaces, so the proper repair here was both together.

The owner also had a full major service due, so we recommended doing everything in the same visit.

We renewed the brakes on all four corners and completed the major service in the same visit.

Brakes (all four corners):

• Replaced front brake pads, front brake discs and front brake wear sensor.
• Replaced rear brake pads, rear brake discs and rear brake wear sensor.
• Road tested so the new pads and discs could begin bedding in.

Major service:

• Engine oil change with Shell 5.5L.
• Throttle body clean.
• All four spark plugs replaced.
• Transmission oil change.
• Brake fluid changed.

After all work was completed we road tested the car before handover. The car went home with fully renewed brakes and a fresh service.

This job, done alongside a full major service (engine oil, spark plugs, transmission oil and brake fluid), came to roughly $2,200 before GST in total.

The brake cost itself (pads, discs and sensors for all four corners with labour) was $1,475 before GST. The service items added to that cost but saved a separate visit. BMW brake discs are worn at the same time as the pads on a car where the disc thickness is marginal, because fresh pads on worn discs bed in poorly.

We inspect and quote for exactly what needs replacing before any work begins. You see what we found and decide.
