Review on 🚗 Autel MD806 Car Diagnostic Tool: Advanced 4 System Scanner for ABS, Engine, Transmission, SRS - Ideal for Mechanics and DIYers by Abaraham Duvernot

I recently bought a 2008 BMW 650i convertible and it had a few minor issues. Finally, an error message came up that the PDC system (Parking Distance Control) had failed. The PDC system is extremely simple - just a couple of small sensors on the front and rear bumpers and a control unit in the trunk. However, since these are non-replaceable electrical parts, you can't just buy a new sensor (they cost over $200 each) and swap out parts until you find the source of the problem. Instead, you must be able to identify the problem FIRST before you can begin troubleshooting. To do this I need a code scanner that can do more than $30 base units. I was watching a YouTube video of a guy diagnosing a BMW PDC fault using a scanner on this particular model, so I decided to pull the trigger and buy it. I was a little nervous because there appear to be two different versions of the MD802 scanner - one is a more limited version that only handles "4 systems" and the other version (which is physically identical) can handle "all systems". " read. This worried me that I would somehow select the wrong block and it wouldn't be able to communicate with my machine's PDC computer. Well luckily everything worked out. My code reader arrived today (VERY fast delivery). I just plugged it into my car's OBDII port and started reading codes (I had LOTS of codes on my car, which apparently isn't uncommon). Anyway, I finally found the menu for the PDC computer, read the codes and indeed it told me exactly which parking sensor on my car was faulty (front, middle, right). I confirmed this by pulling the sensor out, swapping it with one of the other front sensors, clearing the codes and then putting it in gear to trigger another error message. I was very happy to see that my code reader now correctly reports the failure of the other front parking sensor (because I moved the faulty one to this spot). Now it remains to order a new sensor. Once replaced, this code reader pays for itself - I don't even want to think what a BMW dealership would charge for this simple job. So I've only had this device for a day, but so far I'm 100% satisfied with the result.
