Received the new Launch VII+V2.0 code reader Tuesday. Finally got to plug it into the car Wed. evening and though it would not scan Chrysler Crossfire, as suggested in some cases, it would scan using the R 170 /SLK 320 .It found four codes in the antilock and airbag modules. they included c1012 ,terminal 87 overvoltage, c1140, streering angle sensor, c1141, Pressure sensor, c1202, fault can be ignored,??
So, after clearing the codes, I took the car for a drive and found that even after steering wheel reset, the BAS light would not go out. But after reaching highway speed, the spoiler did automatically deploy and then later retract correctly. So, I am going to clean the brake pressure sensor contacts and give it another shot at turning the light off. But I will likely have to order an new sensor, seems that can be a solution to the light , in what I have read.
For $107, shipped from an EBay supplier, I would say the scanner is worth the money. Wish me luck on moving slowly forward toward outing that light!
