Problem((Quote from http://bmwcoders.com/forum/)
I am new to using rheingold 3.43. so im working on a e46 and i discouvered that the dme was burnt
so i got a new one and i want to code it to work with the ews, so when i go onto the coding application on rheingold it says vehicle voltage is under the threshold of 13 volts and it ends the session
so basically i cant code anything . i put in a new battery and its doing the same thing. please help
Solution:
If the voltage is under 13v, coding function not available
Change battery can not solve this problem either
You need to connect external power supply like Automotive Programming Dedicated Power 14V/100A for Audi/VW/Benz/BMW
Or MST-80 Auto Voltage Regulator Diagnostic Tool For GT1/OPS/ICOM Programming User-Friendly
