Here are my first experiences and impressions with the Otofix D1 Lite:
The system was already preset to German when I turned it on for the first time.
After I connected it to my Wi-Fi, the Otofix immediately requested 33 updates, which I was able to download straight away after registering the device with Autel.
The 64GB storage capacity seems sufficient at first. I have all the latest updates installed and there's still 23GB free. Additionally, you could also insert a 32GB SD card.
The Wi-Fi module in the Otofix isn't the fastest. It only runs at up to 5 MB/sec., so you can easily allow 30 minutes for all the updates to be downloaded and installed. When connected to Wi-Fi, it can operate not only in the 2.4 GHz but also in the 5 GHz band. Perhaps it will run faster using the included USB-C/RJ45 network adapter if you connect it to the PC via that. I'll test it next time. I
'll also set up an email account on the tablet so that I can also send error reports as PDFs.
Now for the first time, I got to the car, plugged in the VCI, and... the VCI also wants an update.
Okay, I started that too. However, updating the VCI requires a USB-C to USB-C data cable, which, of course, isn't included in the delivery. :(Luckily, I had one at home and was able to continue with the VCI update without any problems.
Next, it was time to diagnose our T245 (B200). The chassis number was read directly from the vehicle using the "AutoVIN" function. After adding further vehicle information that was requested (year of manufacture, left-hand drive), the diagnosis continued immediately.
The "AutoScan" finds ALL control units installed in the vehicle during the diagnosis; in the case of our B200, that's 22. I compared it 1:1 with an older protocol from a short test of a Mercedes Star Diagnosis, and the control units match 100%. Two errors were found, the exact error codes and texts of which can then be viewed. All in understandable German. I immediately deleted the errors. I've attached the error report, which I sent to myself via email.
I haven't tried the actuator tests on the B200 yet, but I have on my E400 (S212). There, I accessed the front left door control unit and, for example, operated the window regulator via the Otofix and switched the mirror indicator LEDs on and off. It works perfectly.
You can't program/code control units with the Otofix D1 Lite. For that, you would need at least the Otofix D1. The Otofix website has a complete overview via a search mask of what can be done with which device on which vehicle. If you export the lists to Excel, you can also compare the functionality of the individual devices.
Conclusion:
For my purposes, the D1 Lite is absolutely sufficient and, in my opinion, for a multi-brand tool that, in addition to comprehensive error diagnostics, even includes actuator tests and numerous service functions, offers unbeatable value for money in its class. After two years, updates are subject to a charge (119 USD / approx. 150 EUR per year), but as far as I've read, an update isn't absolutely necessary, so you can continue using the Otofix without further updates.
Since Carly had another software bug and was no longer able to detect all the control units in my vehicles (it's since returned to normal), I'll only carry the Carly adapter in my glove compartment for emergencies. For comprehensive troubleshooting, the Otofix is far superior. For diagnostics and other vehicle functions, the Otofix is definitely worth the price.
So, in my opinion, a clear negative point for the Otofix is the rather slow Wi-Fi connection. Luckily, you don't need it too often; only for updates or if you want to send a report via email.
