OEM Euro light switch
Price: $158 (USD in 2014)
Ordered Nov. 18, 2014; Delivered Feb. 14, 2015
Tools required: Hands
Installation time: 30 minutes (with coding)
Grab the right side of the vent* and firmly pull straight out to remove.
Metal tabs hold vent in place.
Note bottom seam of black trim piece is behind top of airbag cover.
Gently pull straight out to remove black trim that surrounds light switch. There are three metal tabs holding trim in place.
Removing switch plug takes some force. There are no metal tabs.
Reinstalled. Four tabs — two on top, two on button — hold the switch inside the black trim. Gently pull away trim from tabs and slide out light switch to remove. (Forgot to photograph.)
After taking delivery of the i3 in November, the first to-do on the farkle list was installing a Euro light switch. I live in a rural, and often foggy, area and having this option brings me peace of mind. The switch arrived on Valentine’s Day, nearly three months later. Waiting** was the most difficult part of this install.
On two previous 3-Series (E46 and E92), the Euro switch was plug-and-play. It activated the rear bulbs and awakened the icon in the instrument display, with no coding required. This isn’t the case with the i3. After plugging it in and pressing the rear-fog button, no lamps illuminated in the rear bumper, and the icon in the instrument remained dark. So I cracked open the world's worst laptop.
Bulb 7 is the rear-fog light, according to the BMW training manual, and their designation trumps all. Forum member PhilH, who is in the U.K., confirmed that bulb 7 is the one linked to the switch from the factory. I hoped coding these settings would illuminate it and the instrument icon:
3068 > NSL_Verbaut Set to: verbaut
3064 > Mapping_Nebelschlussl_L_output Set to: nsl_l
3064 > Mapping_Nebelschlussl_L_Function Set to: nebelschlusslicht
3064 > Mapping_Nebelschlussl_R_output Set to: nsl_r
3064 > Mapping_Nebelschlussl_R_Function Set to: nebelschlusslicht
Coding 3068 NSL_Verbaut activated only the icon in the instrument cluster; all bumper lights remained dark. But adding 3064 > Mapping_Nebelschluss turned on bulb 5, which BMW designates as turn signals. These flash as the emergency lights when the trunk is open. The brightness of bulb 5 is similar to the tail light (1). Until I can figure out how to activate bulb 7, these will do.
Codes from the F30/F32 cheat sheet compiled by Halsifer. Many work well in the i3.
* It’s remarkable how weightless the vent and trim pieces feel. BMW and its vendors sweated over every
gram in the i3.
** As forum user SSi3 noted
, the rear-fog blank in the U.S. light switch might be modified to activate the rear fog. That would have shortened the wait. Trimming the tabs, though, seems tedious. I'd mess it up. But savings galore if you can pull it off.
