{"product_id":"bmw-relay-2","title":"Original BMW White Normally Open Relay with Reverse Polarity Protection for BMW 3, 5, and 7 Series, M3, and M5 (1984–2001)","description":"\u003cp\u003eBuilt with a reversed-polarity guard, this Original BMW white normally open relay, part 61-36-1-729-004, switches high-current circuits in BMW 3, 5, and 7 Series cars plus the M3 and M5 from 1984–2001. BMW calls it the relay for NO contact, white, and lists the polarity guard in its description, which protects the relay if voltage is applied the wrong way across it. It is a light unit at 3 g, in production since July 1988, and it supersedes 61-36-1-729-005 with BMW marking the change exchangeable retrospectively. Made in Portugal. In plain terms, a relay lets a small switched current energize a coil that closes contacts for a much larger load, keeping that load off the switch or control module.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eMany BMW owners know this white relay as the DME relay, and the same part also crosses to 12-63-1-711-266, 12-63-1-729-005, and 12-63-1-729-004. BMW's data spans an unusually long run of chassis: E28, E30, E32, E34, E36, and E38, plus the E31 8 Series, Z1, and Z3 M, with engines from the M20 and M30 sixes to the S38, S50, S52, M60, M62, and M70. \u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Genuine), made in Portugal\u003c\/li\u003e\n\u003cli\u003ePart number: 61-36-1-729-004\u003c\/li\u003e\n\u003cli\u003eBMW part name: Relay for NO contact, white, with reversed-polarity guard\u003c\/li\u003e\n\u003cli\u003eWeight: 3 g (0.11 oz)\u003c\/li\u003e\n\u003cli\u003eProduction start: July 1988\u003c\/li\u003e\n\u003cli\u003eSupersedes: 61-36-1-729-005, exchangeable retrospectively\u003c\/li\u003e\n\u003cli\u003eCross numbers: 12-63-1-711-266, 12-63-1-729-005, 12-63-1-729-004\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003cli\u003eWarranty: 24-month parts warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs this the DME relay on my E30 or E34?\u003c\/strong\u003e\u003cbr\u003eIt is commonly sold as the DME relay and crosses to the 12-63 DME relay numbers shown above, though BMW uses this white relay in several positions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow can I tell if mine has failed?\u003c\/strong\u003e\u003cbr\u003eSystems it powers start working intermittently or quit.
