ABS Control Module - 2011 528i

When harvesting a BMW ABS/DSC module from a 2011 528i in the junkyard, verify the N52B30 engine and confirm the vehicle is rear-wheel drive, as xDrive models use incompatible hardware. The module carries OEM numbers 34526853237 or the later 34526864627, often showing Bosch casting marks like 0 265 250 645 on the aluminum housing. Inspect the hydraulic block for brake fluid contamination or corrosion around the pump motor—these are common failure points on F10 chassis cars. Check the electrical connector for bent pins; the 12-pin variant is specific to 2011-2013 N52 applications before the 2014 LCI facelift introduced updated electronics. Remember that BMW requires ISTA programming to marry the module to the vehicle's VIN; a used module will trigger fault codes and disabled stability control until properly coded. Always remove the entire hydraulic assembly with brake lines capped immediately to prevent internal valve damage.
