BMW 740Li Major Service and Brakes: A Flagship 7 Series Looked After Properly

The owner brought in a BMW 740Li, the long-wheelbase 7 Series flagship, for a major service. The car was a higher-mileage example that the owner clearly wanted to keep in good shape. He also asked us to quote for a leaking power steering pump valve and to replace the undercarriage cover.

A 7 Series is a big, heavy car that asks a lot of its brakes and its servicing. On a flagship like this, skipping a service or running brakes down to the metal does not save money, it just turns a planned job into a bigger bill. The owner wanted it inspected properly and a clear quote before anything was done, which is exactly the right way to look after a car like this.

We ran a full inspection before quoting anything. The battery checked out at around 90 percent, still healthy, and all four tyres were in good condition.

The brakes told a clearer story. The front pads were down to about 20 percent and the rear pads to about 25 percent, and on both axles the discs were worn, so pads alone would not have been enough. The leaking power steering pump valve the owner asked about is not sold on its own, so the fix was a whole pump. We also quoted a replacement engine oil sump, which the owner chose not to go ahead with. We listed every item, with the cost of each, and let the owner decide what to proceed with rather than deciding for him.

With the work agreed, we worked through the list properly.

• Major service: replaced the engine oil and oil filter, cleaned the throttle body, and changed the brake fluid.
• Brakes: replaced the front and rear brake pads and discs, with new wear sensors.
• Fitted a replacement undercarriage cover.
• Power steering pump: the first pump from the supplier did not suit the car, so the owner collected the car after the service and brakes and came back a few days later, when we fitted a pump reconditioned from original parts.

We used OEM-grade parts and kept the owner updated with photos as we went. The service, the brakes, the undercarriage cover and the power steering pump came to $3,800 nett. Every line was agreed before we started.

What a 7 Series major service with brakes costs depends on how much the car needs, which is why we quote item by item. A straight major service with one axle of brakes sits lower. This car needed more: a full service, front and rear pads, discs and wear sensors, a replacement undercarriage cover and a power steering pump, which came to $3,800 nett. Before GST that was $218 for the oil and filter, $50 for the throttle body clean, $88 for the brake fluid, $1,725 for the brakes and $225 for the undercarriage cover, plus $1,500 nett for the pump, less a discount. A replacement oil sump was also quoted, but the owner chose not to go ahead with it, so it is not in that figure.

What moves the price is what the inspection finds. A flagship that has been kept up to date might only need the service and one set of brakes. A higher-mileage car that has waited longer picks up extra items like a steering pump or a weeping gasket. This is why we inspect first and quote every line, so you only pay for what the car actually needs and you decide what to proceed with.
