Finally I found bypass valve power wires were crossed, see ruclips.net/video/ErUmGlUafo4/видео.html Crossed power broke valve when ignition was turned on. Also another used one broke before I found crossed wires. No programming needed, just plug in. Usually problem is on faulty K40 relay module that doesn't deliver enough power to supercharger clutch or to bypass valve. Check voltage on K40 fuses F2 and F3, should be around 12 V. K40 middle relay powers those fuses.
I have the same code on mine it started when i accelerated to hard and went into limp mode, my bypass valve only starts closing at around 2100 rpm and thats when the SC engages and closes completly at 3200. Cant push the gas to hard or goes into limp mode , hate it.
What happened did the other bypass valve work or did it need programming if u get n used one also having the same proplem mine is not closing

Limp mode should come only if your transmission slips. First thing is to check transmission oil level (you have to get oil stick or go to MB dealer).
