How to Test and Check Mileage on BMW (Using Launch X431Tool)?

This article will show you how the Launch X431 V 8 inch compares to BMW in terms of mileage. The methods and tools are not limited to X431 scan tools, but are also applicable to other scan tools.

Model: F-series M30 2012
Categories
Tool: Launch X431 V

Km on ECM

First we enter scan menu.

Select

System selection>>Drive>>ECM (Engine Control Module – DME/DDE)

Enter “Read Data Stream” “Diagnosis Request” as we need current parameters. Scroll down and check “Kilometre Reading” and “Operating Hour Counter”

Then we have hours and kilometers, but not very informative.

Km on TCM

Now go back and enter “TCM (Transmission Control Module – EGS)” menu.

Also read data stream.

Enter “Operating Variables”.

Check “Mileage/Km Reading”, slightly different from the previous one.

Km on ABS

Back to system selection menu, go to

Chassis>>ABS (Anti-Lock Braking System – DSC)>>Read Data Stream>>Run Flat Indicator

Here we have a great number of options about mileage.

Select all options.

Then we need to go into three blocks: ABS, engine and battery.

Km on Battery

Back to scan menu.

Here is the general scan, what we need is to go into special function and find power supply.

Select

Special Function>>Body>>Register Battery Exchange

Press “F1” to start the procedure.

Before step “F2”, here is the last and last two replacement of batteries.

Km on CBS

Then we want to know where it has the kilometers without driving.

Back to the special functions menu.

Select

Maintenance>>CBS Vehicle Data Correction

See F1-F3, how many times oil and brake changes are.

Km on DTCs

In addition, you should scan all fault codes if you’re wondering about a check car.

Then care the ones that go into modules about mileage.

Enter them to check generally, and details including freeze frame…

Of course sometimes they didn’t work, didn’t show you the real things, but sometimes the hack-work about mileage can be detected.

Km on Freeze Frame

So now we go to read freeze frame.

It gives you another mileage.

On Maintenance, no control messages for BMW.

Control messages depend on RAM, and you should check it if there is an option.

Alright, general scan for mileage is time-consuming work but very useful. This is the first important thing you should look at during diagnosis.

Hope this could help!
