I tried to order a Retarding Relay (13.90 1 311 772) from BMW NA via my dealer. It is backordered without a ship date. Argh.
I'd really like to be able to drive the car home for Christmas. But as of now its a driveway ornament.
Anybody out there have a spare? I don't know where this relay is located in an E30 as my S14 sits in a 74 2002tii.
