Why Should Buy This Product?
From the comparison table, we can see the LAUNCH V+ 4.0 does almost everything from reading codes to ECU coding and everything in between, featuring far more functions than V 4.0. The likely benefits include some of the following:

  • It skips the frustration of learning a new tool, featuring valuable Guided Functions for VW / Audi / Skoda / Seat.
  • It is compatible with the HD module, thus being able to turn itself into a professional scanner for commercial vehicles, to avoid unnecessary costs for buying heavy-duty scanners.
  • Its enhanced constructions, such as durable LENOVO tablet, advanced 8-core CPU, powerful battery system, bigger & clearer display screen, and more, make sure it is running smoothly and efficiently to catch all of your vehicle’s potential issues.

Even with that high-grade performance, it only costs a few hundred dollars more than V 4.0, while the latter tends to be out of date.

OE-Level Functions Detailed Overview
Made by the LAUNCH technologies, you are bound to see why most people run over heals buying this pro-level scanner.
Loads of OE-Level features are covered as Guided Functions / Online Coding for VW / Audi / Skoda / Seat, Setting & Changeover (adblue reset, unlock the engine after a collision, cancel ABS driving test, and more) for Benz, Modification for BMW, and Offline Coding, Customization / Personalization, for worldwide vehicle brands, and keep growing:

1. Guided Functions for VW, Audi, Skoda, Seat
This is the function that any professionals need, if they want quick and accurate car diagnostics for VW, Audi, Skoda, Seat.

  • Only available in V+ and higher-grade diagnostic tools in LAUNCH;
  • It provides advice and suggestions for carrying out all the diagnostic procedures in a more streamlined way, to help enjoy simple step-by-step procedures at fingertips, without going through a lengthy or complex process;
  • A much more effective and comfortable way to help resolve many tricky issues in various vehicle systems including engine, gearbox, brake, airbag, instrument, air conditioner, and more., than most competitors in the industry.

2. Online Coding for VW, Audi, Mercedes-Benz, BMW, Seat, Porsche, etc.
Car coding is a relatively new thing in the automotive world.
It implies software modifications to a vehicle to allow the use of functions not available in the car when it left the factory for different reasons, mainly local regulations.
Also, if you want to configure a vehicle’s control unit with additional parameters then LAUNCH V+ 4.0 can help you to effectively accomplish the task in compliant vehicles.
Noted that the online coding does not imply changing the software! It only changes preprogrammed options already existent in the software:

  • To perform the customer individual customization of the car such as 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.

3. Bi-directional Control (active test)
Essentially, LAUNCH V+ 4.0 is a professional bidirectional scan tool. The scanner can perform system tests as well as actuate injectors, relays, and coils, etc., by sending and receive commands to and from the system, so as to help you determine the efficiency of that particular system.
So as a user, you can observe how the system parameters change in real-time. That will tell you whether it is performing optimally.
For example, a bi-directional ABS test will allow you to send commands to the ABS system, in the same way, the car’s on-board computer would.
By observing how that system responds to the commands, you can determine whether it would respond to the ECU’s commands as required. If not then it means there’s a problem that needs fixing. If so then your ABS is clean as a whistle.

4. 26 Most-Commonly Used Maintenance Services
LAUNCH engineers have been committed to making the modern vehicle routine maintenance as user-friendly as possible, aiming at giving the users the perfect scan experience with 26 maintenance services in this diagnostic tool:

Superb Constructions to Facilitate Your Work
As a phenomenal diagnostic tool kit, it has literally got everything you want to make sure the maintenance or repairs are going as smoothly as you imagine.

1. Durable LENOVO Tablet
At first sight, the LAUNCH V+ 4.0 looks a whole lot like an ordinary Android pad. It is in fact a LENOVO tablet.
I think many will agree that LENOVO tablets in terms of design almost never surprise. Manufacturers rarely experiment with the appearance, but with materials. So this well-constructed tablet seems to be able to last long, and defy tough conditions around car repair shops.
Also, it fits in a hand as comfortably as any tablet, with a weight of just 2.31 pounds, so carrying it around shouldn’t be a problem.

2. Stable & Smooth Operating System
The scanner runs on an Android OS 9.0, which further optimizes the efficiency of the operating, including the installation, and the running of the software. The fluency problem that Android users are most worried about has been greatly improved. In less than 10 seconds it will be fully powered up and raring to go.
Besides, the system is quite user-friendly. Those who are familiar with Android smartphones or tablets will find this tablet breeze to operate, and even those who are not familiar will find it easy to pick up and use.

3. Amazing Multitasking
The device is designed to provide a space for ideal management of the multiple operations running behind the system, backed by the powerful Qualcomm Snapdragon 450, 8-Core 1.8GHz processor, and 3GB of RAM.
The users can handle more than one function at the same time without messing up with any complex operations, and are at peace in getting fast data coding and repairs.
Multi-tasking also helps to manage the data records and other vehicle info in an organized manner.

4. Display and Interface
Navigating the LAUNCH V+ 4.0 is pretty simple thanks to the touchable screen, which is highly responsive to user input.
The 10-inch screen is pretty large, making it easier to read and allowing more information to be visualized at once.
Also, with a resolution of 1920*1200P, the display boasts of crisp clarity. It is bright and sharp enough to see in any light condition, being definitely one of the clearest diagnostic tablets available on the market today.

5. Useful Cameras
There is a built-in 5MP front camera, and an 8MP rear camera with autofocus capability for taking snapshots for further analysis. Saving that and all the diagnostic data/files are quite easy thanks to the 32GB worth of space (which can be expanded to 128GB) at your disposal.
Whenever you need to record images, its powerful cameras will help you get crystal clear shots. And since the device is Wi-Fi enabled, you can share the pictures online with technicians and other experts or DIYers. They may help with whatever problem you are facing.

Finally, the built-in 7000mAh battery keeps the tablet going even when it’s not connected to a power source.
It allows you up to 8 hours of continuous use without charging, which is a lot more time than you will get in other professional automotive scanners.
This is quite useful when you are using Bluetooth or Wi-Fi to run diagnostics.
