I retro fitted the auto levelling to my C43 the loom is unavailable from MB I salvaged mine from a scrap 43 together with two suspension sensors, and ECU, I was dreading fitting the loom but to be honest it was quite easy, the hardest part was fitting the brackets on the suspension though in retro spect it was,nt hard took about two hours to fit the suspension sensors and route their cables into the car. Their is a WIS work Instruction specifically on fitting the levelling loom and another for the suspension sensors, you could salvage the loom from a 210 or 208 equipped with Xenons as i don,t see any reason why they would be substantially different, in the case of the 208 one I would think they were the same as a 202.
