I had to pull the bumper on my 1er last night. It started about a month ago when I washed it and unknowingly dislodged one of the headlight washer covers. A few days later said headlight washer cover flew away to parts unknown leaving an ugly hole in the bumper. I ordered a new cover, but didn't find a good DIY for installation so I broke the washer when trying to get it together. Turns our there is a very easy way to remove the washer nozzle from the pump snap the cover on and re-assemble all of it... who knew.
So yesterday I got the pump and went through bumper disassembly 101.
It took about an hour, but I got everything apart, fixed and back together pretty flawlessly. I was quite pleased with myself.
This morning I started it up to go to work and got a TPMS inactive error. FML, I forgot to reconnect the receiver in the wheel well liner before I screwed it all back together. I guess yesterday was just a practice round
