Launch X431 PROS Mini Function:
1. Full System Diagnose:

LAUNCH X431 PROS MINI can establish a data link to all systems and subsystems of the vehicle being serviced to:
1) Retrieve ECU information of the tested control units including unit type, version numbers, and other specifications, etc.
2) Read & erase DTCs to locate problem areas and clear the codes.
3) View Live Data of each parameter item.
This comprehensive scanning process is able to locate the faulty systems and retrieve the DTCs related easily.So you can work on all parts of the vehicle systems to enhance the performance, save energy, reduce emissions, and everything else.

1) Access to Vehicle's All Modules

With all system coverage, you will not have to purchase a separate device to perform different functions.The following is a list of modern vehicle systems that this scan tool can get access to:
* Engines/ Auto Transmission/ Airbags/ Immobilizer/ Key Coding/ ABS/ Cruise Control/ Instruments/ Self Leveling Suspension systems
* Seats/ Doors/ Gateway/ Steering Angle/ Air Suspension/ Body Systems/ Electronic Power Steering & Motor Assisted/ Power Steering/ Tyre Pressure/ Rain Sensors/ 4WD System Stabilizer/ Intelligent Parking Assist/ Door Motors/ Audio Systems/ Air Conditioning/ Tiptronic/ Anti Theft/ Soft Top/ Headlamp Leveling/ Central Locking/ Automatic Clutch/ DPF Reset
* Electric Windows/ Plip Programming/ Heated Rear Window/ Xenon Headlights/ Wash Wipe/ Fuel Burning Heater/ Transfer Box/ Seat Memory/ Oil Life Service Reset/ Sliding Doors/ Electronic Throttle

2) Advanced Bi-Directional Functions
The LAUNCH X431 PROS MINI is actually a bi-directional diagnostic tool, because it can be used to request information or command a module to perform specific tests and functions. Furthermore, you can use it to do some tests like turning the fuel pump on and off, cycling the a/c clutch on and off, even performing an evaporative emissions leak test. When it is properly utilized, bidirectional component and system test can significantly reduce the diagnostic time.

3) ECU Coding for Functionality
Launch X431 Pros Mini offers the ECU Coding feature,which is not available in conventional code readers, to allow you:
* To perform the customer individual customization of the car such setting alarms, doors locking, and outdoor lighting, etc., to improve vehicle performance, or stimulate high-end car functions.
* To alter the configuration when a component is replaced, so the new actuators can be recognized by related vehicle systems.
* To enable multiple car systems to recognize each other, and so the actuators can start to work.

4) Active Test for Effectiveness
With this diagnostic tool's Active Test, you can output the command into the ECU in order to turn on/off actuators, to find faults in the subsystems of your car effortlessly. For example, when you carry out an active test on a radiator fan, if the radiator fan is working then it is fine.But if not, then there might be an issue with the wires, replays or the fan.

5) Record & Playback
Another great feature about this automotive diagnostic scanner is that, it would allow you to view the Live Data Stream, and to record the data in Waveform. This would save you the hassle of reading through and digesting all the information which is being presented to you. You can even playback these data, for better analysis and rectification as well as the future use.

6) Share Report via Wi-Fi
Rather than taking the additional hassle, with this Launch scanner, you would easily be able to share the diagnostics report to your clients or technicians via Wi-Fi. They would take a look at the full, clear and accurate diagnostic report, and then understand about what would need to be done.No more Googling unreliable fixes that would waste your energy.

Launch engineers have been committed to making the modern vehicle routine maintenance as user-friendly as possible. Now with this diagnostic tool, you can easily do functions like:

1) Oil Reset: Close the oil service light and reset service mileage & service interval after replacing the engine oil.
2) Injector Coding: Write the new injector numbers into the ECU for accurate communication and injection control.
3) EPB Reset: Reset the new electronic parking brake for braking wheels safely again.
4) SAS Reset: Clear memories of the previous steering angle sensor and store the replaced one.
5) TPMS Service: Relearn TPMS sensors so that new sensors can be recognized by ECU.
6) ABS Brake Bleeding:Get a firm brake pad after air exhaustion.
7) BMS Service: Perform a reset on the vehicle battery for clearing the fault information and re-match the battery.
8) DPF Service: Clear particulate matter from the DPF filter to stabilize the filter performances
9) Tooth Learning: Finish tooth learning after changing crankshaft in the car engine, so the new part can be used.
10) Throttle Matching: Initialize the throttle actuators to the default state for regulating throttle (or idle engine) operations accurately.
11) Anti-theft Matching: Disable the lost vehicle keys and write the key information into the replacement.

3. Other Functions:

* Data Stream record and playback: Record and playback the data stream help you analyze the trouble when driving and solve it. 
* VINSCAN: Automatic scan (OBD VIN) and manual input (INPUT VIN) are available.
* View History: Generally once a vehicle diagnosis is performed, X-431 PROS MINI will record the every details of diagnostic process. The History function provides a quick access to the tested vehicles and users can resume from the last operation, without the necessity of starting from scratch.

Tech Service

Car model and year: Porsche Cayenne 9Y0 2020 with 30,000 miles


Purpose: to do service reset



Got all the tools. BMW uses those spark plug sockets. Or at least the one I have is the right size.

I have a membership at PIWISTIS so the Porsche instructions with the toque specs will be there.


Just need to confirm the part number. The cheapest tool that will work on a 2020 cayenne in the Launch X431 ProS Mini.


If more the cayenne stores what service was done when. I paid for a brake fluid change and the didn't mark it. I wonder how I can fix that.



Part number is available at FCP for $30/each. X431 ProS Mini Scanner is $750. So for an extra $100 if I can DIY every other one will be $20 for shipping.



Step 1 done. Confirmed the launch x431 Pros Mini was confirmed to work by the company.

Today going or download the instructions. The good news is Of this works I can start to do my own oil changes.


Step 2 failed. There is a new PIWIS TSI site. You have to register, confirm you are a business, and promise not to share. So I applied for access and waiting to hear back.

---Well I am now a Porsche Partner network member. I think that means I can now access all Porsche repair documents. Downside is you have to agree not to share.


What do you need to do to become a Porsche Partner network member?

You have to fill out an application. With a business name and address. Then they review your application and grant you access. You have to swear to not share anything with anyone.

Then to actually see any documents it's $17/hour. Maybe $57/24 hours. And something like $3000 for a full year.

Once you learn to navigate it there is a lot of useful information. I buy an hour when I have a Porsche repair or service and then I print what I need and file it in a binder. The printed pages have a water mark with your name and the date across it so you can't copy and sell it.

I have done all the service on a 997 and a Macan with it. Including the 57 steps to remove the front carrier to change the belt and tensioner. It is very specific with pictures and torque specs.



As our hero continues to respond to himself...


Everything ordered

Launch Pros mini $779 off of

Spark plugs $180

1 hour to download instructions $17 at PPN


So to save $800, I just spent $1040


Will let you know how it goes


The TSI turned into the PPN. But when I put in my VIN all the information including service a s extended warranty come up. Pretty cool. Does not have a parts diagram I can follow.


You may find this to exploded parts diagrams helpful:

Those are the plugs I ordered. $29 each from FCP

Porsche Cayenne 9Y0 2020 service reset (using X431 ProS Mini)


Check out the link I posted. It takes you to the LLL Parts site which contains an expansive library of diagrams for Cayennes:

After selecting the year you will see the page, below. Careful, you can burn lots of time going through the diagrams. Quite educational, though!



Launch Pros mini arrived today. It will communicate with the car. Will see if it resets the intervals when the time comes. Also looking to see if it can add when the service was done to the PCM. They forgot to add the brake fluid change and according to the PCM the final drive fluid has been changed 3 times. Now just waiting on the plugs.


Hope it helps!
