Pros & Cons of the CRP919E BT
CRP919E BT

Like every diagnostic tool, this device also has its pros and cons. In the following list you will find the advantages and disadvantages we think are relevant:

Pros:

Comprehensive vehicle coverage: The CRP919E BT supports over 120 brands and more than 100,000 models worldwide, making it a universal diagnostic tool.
Detailed diagnostic report: As the CRP919EBT accesses almost all control units in the car, it is able to detect even the smallest faults, such as a mini short circuit on the loudspeakers
Bidirectional control: With this function, you can carry out active tests to check the integrity of vehicle systems without using the vehicle control unit.
ECU coding: Allows you to carry out coding on the vehicle, such as canceling the V-Max.
Wireless connection: Thanks to the VCI Bluetooth adapter, there is no need to fiddle with cables.
31+ maintenance functions: These cover almost all maintenance requirements, from oil resets to calibrating the tire pressure sensor.
Android functions: In addition to all the functions for diagnosing and maintaining a vehicle, you also have all the functions of an Android tablet. You can download apps, surf the internet or answer emails with the Launch diagnostic device.

Cons:

Update licenses: After two years of free updates, the updates then cost around €200 per year. However, you can continue to use the device as normal.
ECU coding not universal: Just as with coding apps via the cell phone, not all codings are possible for all vehicles. Mercedes may only have two, while BMW has countless coding options.
Üdoes not translate everything to 100 %: If you want to translate the launch to another language, you must assume that not everything will be translated 100 % correctly, or that it will simply continue to be displayed in English.

Reading Data Stream Test

To measure PID's or to record individual sensor parameters, instead of navigating to the "Health Report" tab go to the tab "System Selection". In this menu, select the tab "Drive" and click through the selections depending on your vehicle data.

"System Selection" menu
Menu path: "System Selection" for live data evaluation
"Drive" menu
Menu path: "Drive" to be able to monitor the motor data & parameters

Once in the menu, click on the button "Data Stream" and select the areas or individual values that you want to view in real time and analyze them.

This live data can also be recorded (log drive) and exported as a CSV file. You will then find the CSV in the following path: Other modules → Folder → "Local - Start directory" tab → CNLAUNCH → CRP919BT → images. However, you can also view the log directly on the diagnostic tool and display it graphically.

Perform DPF regeneration

The DPF regeneration can be found in the same menu as the previous maintenance functions that we have shown you. Under "Special Functions", when you look for "Diesel particulate filter regeneration" you can select whether you want to regenerate the particulate filter while stationary or while driving.

ATTENTION:

During diesel particulate filter regeneration, exhaust gas temperatures can reach up to 700 degrees. Make sure that there are no flammable substances behind the exhaust. In addition, more exhaust gas and black smoke will come out of the exhaust.

Perform DPF reset

The DPF reset is located in the menu "Special Functions"where the DPF regeneration is also located. Navigate to the button "Initialization After Component Replacement".

"DPF reset" menu

Should you only once want to briefly read out the fault memory, this is not the device you need. In this case we recommend something like the MUCAR CS4 or similar devices with a even smaller range of functions. The Launch diagnostic device can do a impressive amount more, but it also costs accordingly more money and may not fall within everyone's budget.

But if you are looking for a diagnostic tool that leaves nothing to be desired, the Launch CRP919E BT is definitely the right investment for you.
