Clutch Master Cylinder, URO - E30, E28, E24

This part is listed by BMW as BMW part number 21521156000 (21-52-1-156-000) and is described as the Clutch Master Cylinder for E30 318i/325e/325i/325iX/M3, E28 528e/533i/535i/M5, and E24 633CSi/635CSi/M6 (from 9/82 production date). 

Does your clutch pedal go to the floor, and doesn't come back up? Then you may have suffered a clutch hydraulics failure. If either of the clutch cylinders fail, you likely left a small puddle of brake fluid somewhere, and now your clutch won't engage/disengage, leaving your BMW stuck in gear. On older BMWs like the E24, E28 and E30 this is a very common failure part.

This part is manufactured by an aftermarket supplier of European auto parts, including many hydraulic components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
