Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

Diagnostics of the most important control units

The biggest advantage of this diagnostic tool is support for the four most important vehicle systems. It can communicate with the engine control unit, automatic transmission, ABS, and the SRS airbag system. This lets it identify most of the common faults that occur during normal vehicle operation.

If the engine, ABS, or airbag warning light comes on, you don’t need to visit a service center right away. The diagnostic tool displays fault codes, their meaning, and allows you to clear them after fixing the problem. Often, you can find out the cause of the issue within a few seconds.

Complete OBD2 functions for modern vehicles

The LAUNCH X431 CRP123E V3.0 OBD2 supports all 10 standard OBD2 diagnostic modes for vehicles manufactured from approximately 1996 up to the latest models. Of course, it includes reading and clearing fault codes, live sensor data display, Freeze Frame data, lambda sensor tests, emissions system readiness, and VIN number display.

A major advantage is the graphical display of live data. The diagnostic tool can display up to four parameters in graphs at once, making it much easier to monitor engine behavior or other systems while driving.

7 service functions for regular maintenance

In addition to classic diagnostics, the device also offers 7 very useful service functions that you can use after repairs or component replacements.

These functions will be appreciated by every vehicle owner who does part of the service themselves or wants to have control over the status of their car without unnecessary service visits.

Automatic vehicle recognition saves time

Modern Auto VIN technology can, in most supported vehicles, automatically recognize the make, model, and year of manufacture. So you don’t need to manually select each item. The diagnostic tool identifies everything itself and can start checking individual systems immediately.

If that specific vehicle doesn’t support automatic recognition, you can still simply select all the data manual directly in the device menu.

Large HD display and Android system

The manufacturer used a high-quality 5-inch touch display with a resolution of 1280 × 720 pixels. The display is sharp, clear, and individual graphs or diagnostic data are very easy to read even while working in the workshop.

Inside, there’s a Android 8.1 system that complements a dual-core setup with 2 GB RAM and 32 GB of internal storage. Power is handled by a built-in battery with a capacity of 6100 mAh, so you can run diagnostics without constantly keeping it connected to a charger.

Lifetime updates—no extra fees

One of the biggest advantages of the LAUNCH X431 CRP123E V3.0 OBD2 model is free lifetime software updates. The manufacturer regularly adds support for new car models as well as new diagnostic features.

The update is easy—via Wi‑Fi directly on the device with a single click. You don’t need to connect the scanner to a computer or download complicated programs.

Wide compatibility with 57+ brands

The device supports more than 57 automotive brands and over 10,000 vehicle models. It handles most European, Asian, and American passenger cars with ease.

However, you should keep in mind that the device is intended for passenger cars with OBD connector voltage of 9 to 18 V. It’s not suitable for trucks or commercial vehicles with higher voltage.
