This thing has potential except I am having an issue with an 08 e2. Car was left in my grandparents garage dead for a year. After I took ownership I Charged each batt individually, replaced speed sensor, tuned and bled brake system, cleaned pin connectors, and seems everything is back up and functioning. Except I can only use low gear max 15mph. I replaced the switch with a brand new one. No difference. High and reverse say code 09 even after replacing. Also is one disc caliper will work but not release quite all the way. I am having a tough time finding answers to either. Thanks
Yes I found this and replaced the switch to no avail.
Not a bad switch. It may be wired wrong or two wires shorted.
Should be 4 wires. B+ and 3 selection wires.
Only one wire at a time must have +72.

I’ll take a look thanks
some gems have their switch wires changed so that they can only go 15mph . Makes them exempt from registration in some states . my guess is the switch wiring
It was indeed. Two wire swaps and it’s high and reverse are fixed. Thanks
