The late production of E30 M3 ABS pumps the BOSCH 0 265 200 042 has ditched the redundant ground (pin #8) on the main chassis connector, and again on the solenoid relay which is characterized by 4 pins unlike the 5 pin used on early models. The solenoids on this pump are specific to the 042 series of pumps. Yes they are M3 specific both in part number AND in the size of the flow through orifices inside the solenoids. The M3 solenoids are higher flowing than their non-M counterparts. The upper manifold plate has lost the bosses for top facing ports found on other models and now sports a sleek upper top plate. The primary difference between the late 042 and the mid 042 is the addition of cosmetic sleeves made of aluminum that cover the solenoid frames. These are finished in a brushed texture (pictured) but can be offered in polished. The sleeves are often not salvageable from core pumps due to galvanic corrosion and as such they do carry a modest premium over non sleeved pumps. The cover shroud and chassis wiring hold down are secured with T15 Torx screws
