Original BMW Multi-Purpose Relay, Zinc Yellow, for BMW 3 Series, 5 Series, 7 Series, 8 Series, M3, M5, and Z3 (1988–2006)

Called the relay in zinc yellow in BMW's parts data, Original BMW part 61-36-1-389-105 is a general-purpose switching relay used across E36, E46 coupe, E34, E32, E31, and Z3 BMWs built between 1988 and 2006. It weighs 30 grams, is made in Portugal, and BMW began producing it in June 1992. A relay lets a small control current from a switch or control unit energize a coil, which closes heavier contacts and powers a high-current circuit without running that load through the switchgear. Because it is a general design, BMW uses this one relay in different positions depending on the chassis, which is why the same number turns up for several different jobs across these cars.

Original BMW Parts carry a 24-month parts warranty.

Because BMW uses this relay in different positions depending on the chassis, confirm the position for your car before you order. BMW applied this relay to an unusually wide range of cars, from the E32 735i and 750iL and the E31 850Ci to the E36 318i, 325i, and 328i, the E46 325Ci, 330Ci, and M3, and the Z3 roadster and coupe. Multi-purpose relays of this type can run fuel pumps, cooling fans, lighting, HVAC components, and wipers, so what this one controls on your car depends on where it sits.
