Konnwei KW850 OBD2 Diagnostic Device

by Dale Philip

The Konnwei KW850 has a similar design to the devices from BGS or Nexpeak. However, the font in the display is quite small, the display should be better. Overall, however, the operation is largely intuitive. When reading out, the Konnwei performs averagely but does not detect the error on the airflow meter of the E-Class as extensively as other devices. In addition, with some errors, the translation is so bad that you can not get ahead without a search query on the Internet.

Also in the menu, some translation errors have crept in, which does not make the operation more difficult but leaves a rather cheap overall impression overall.

Operation: 18/20 pointsFeatures

 

The instructions should gladly contain further safety instructions but are overall very detailed. The illustrations are particularly good, so it is very easy to understand. Although the Ancel device is also a very compact one, the price difference e.B. to the Kungfuren is qualitatively clearly noticeable.

The display is good, the feel is also higher quality than the Kungfuren. However, similar to the Kungfuren, the operation is only possible via four or five buttons. Too bad: The Ancel is the only device that does not display real-time data.

When readout, it reads the AUDI’s ABS error correctly. In addition, it detects the error of the intake manifold pressure sensor. For the other cars, the Ancel EU410, like the other candidates, detects three out of four errors.

The OBD2 diagnosis device from Nexpeak is the screw of the tested products. Not because of the readout speed, but because of the rather delayed operation. You have the feeling that you are sitting in front of a computer with Windows 95: The frames build-up only slowly – this seems cheap and pushes you to the limits of patience. The Nexpeak NX501 OBD2 scanner is the only device that does not read a single error in the Audi.

There is a message “No errors found”. In the T-Cross and E-Class, the device shows a similar performance to the other candidates. The translation of the errors should be a little better, there are sometimes still Internet searches necessary to better understand the meaning.

 

Autophix OM126P

First point of criticism of the device from Autophix: The instructions are only available in English. The actually German menu is full of mistakes. Operation is mainly via four buttons. Similar to the other compact products (e.B. Kungfuren), this is a bit fiddly and only partially intuitive. Practical:

There is a button with which the diagnosis can be initiated immediately. It is the only device that cannot read the vehicle information, such as the chassis numbers, on any of the test cars. Similar to the candidate from Ancel, the Autophix manages to read out two out of four errors in the Audi. With the other test cars, the result is the same as with the other devices: Three out of four errors are found.

 

Konnwei KW850

The Konnwei KW850 shows a solid performance in the test. Externally noticeable: the display is a little dark, in a very bright environment therefore not so easy to read. The instructions do not contain any safety instructions for use. . Practical: The iCarsoft has an extra button to start the diagnostics immediately.  The translation of the codes leaves room for improvement.

 

With a price of around 30 euros, the Kungfuren VP590 is the cheapest diagnostic device in the test. As the only device, it has only a black and white display.  When reading, it emits the same errors as most other devices. So an imprecise error message in the Audi and three errors each in the T-Cross and E-Class. After reading the error codes, the result is listed. The translations of the codes run from top to bottom. Annoying: The speed of the display cannot be influenced. So you may have to read it several times.

 

Compared to the other test equipment, the diagnostic device from Lescars makes the worst impression visually and haptically – but it does not primarily depend on appearances. In terms of operation, the Lescars device makes it quite difficult for users: There are only three buttons, which makes the operation overall quite fiddly and not very intuitive.

Especially annoying:

The enter and exit functions are on one key. Is one of the few, diagnostic devices that does not provide an error code database. When reading out the errors, the candidate performs averagely. ices than the inexpensive universal products. Therefore, it was also tested out of competition.

But the result is clear: If you want the most accurate vehicle diagnosis possible, drive with this candidate correctly. Not only is it the only device that reads out all errors correctly, but it also provides very detailed information on the type of error and the position (e.B. “ABS speed sensor front left”), so that it is very easy to detect the defect. In addition, there is a very intuitive operation and a high-resolution display. Practical: The software updates do not require a detour via the PC, the device can retrieve them itself via WLAN. The only drawback: The instructions are enclosed exclusively in English.
