Three problems related to wiring have been reported for the 2011 BMW 135. The most recently reported issues are listed below.
The same blower motor wiring issue in the BMW 3 series thats causing them to catch on fire and burn to the ground. I have compared the problem with another 3 series with the same exact issue. Although the wiring part number is different, the plug and where the negative and pos terminals are placed is the same exact spot as the 3 series. The car will shut off from voltage spikes when driving and cause sparks and arching noises where there neg and pos wires meet causing both of the wiring housings to melt and potentially cause a fire. I have taken off the kick panel that covers the wires and noticed the kick panel itself was burnt and melted. I have talked to many other 1 series owners and they also have this issue but it's not on the recall list. I believe it should be because this is a very dangerous problem that can potentially injure or kill someone.
Blower mower wiring overheating and burning/corroding while fan was on low speed.
Sometimes the blower motor will not work at the speed selected. A few times have smelled a odd burnt plastic smell. BMW won't help this issue as there is no recall on this certain model. I have took the time to actually diagnose the issue. Wiring to blower motor resistor module affected. Cannot even unplug the connection. Has brown areas on the resister by ground wire of signs of extreme heat.
