Review on Autel MaxiDiag Advanced MD808 Pro: All System OBDII Scanner with Oil & Battery Reset, Brake Pad Relearn, SAS, SRS, ABS, EPB, DPF, BMS by Julian Locklear

I have a general Mercedes transmission problem with the turbo speed sensor code. It got to the point that toggling the key didn't eliminate idle mode. It kept getting stuck in 3rd gear (no reverse). This scanner easily contacted my ECU and got rid of the code. I've been riding for more than a month, the code hasn't come yet. I check regularly, but so far so good. I will eventually replace the gearbox (the previous owner drove it too hard and I think the clutch is worn out) but it drives fine now. The scanner also diagnosed an issue with a missing AC sensor and a few other BCM codes that you can't scan with cheap scanners. The only thing it cannot do (compared to a real Mercedes STAR scanner) is, for example, activate the rain sensor. There are several such things, but overall this is a great bang for the buck.
