I bought an Openport clone from AliExpress, but the voltage regulator burned out after just one week of use. Later, I purchased the BENZ VX800 from VXDIAG official, and it works very well with Xentry.
I've successfully flashed the TPCM module on my W212 with no issues at all.
I have genuine Openport and Scanmatik devices, but they don't allow me to flash the instrument cluster. So I did a lot of research and came across the VXDIAG device. At least in the YouTube tutorials I watched, it always worked very well - and in fact, it really does. It can read data from my Mercedes without any issues.
Openport has a power leak issue. I won't be trying that device again. Just got the VXDIAG, and it looks pretty good so far.
VXDIAG BMW is really great for diagnostics, programming, and flashing. Just sharing my experience-hope it helps you guys!
