~ Got the Autel to try to clear the code...Software update download for the device to obtain MB slk320 specific code, has a requirement to create an online account..a Chinese company wanting all kinds of personal info...I am hesitant. I ordered the DIY (850?) model that I had read about in a different thread about the "stuck in park" issue, I received a unit DiagLink EPB/OLS+CAN OBDII...The similarities to the HarborFreight Cen-Tech tool 60694 OBDII/EOBD tool that I already have is obvious right down to the embroidered , zippered case. The update file extension for the HF tool had an (.aut) extension like the Autel file extensions have. Spoof account I guess, unless I find I can clear the code with the HF tool and return the Autel unit.
