I have a BMS JB+ for the W204 C250. I had it installed and it works well, the problem is I share my car with my wife and she doesn’t like. It feels to fast for her….go figure. Anyway, I took it out. Had it about 2 weeks. Asking $200 and free shipping. One thing to add is I drilled a little hole in the cover, so I could access the adjustment screw without opening the whole apparatus….way easier! just put a piece of tape over the hole, and good to go



Let me know.



Thanks!
