Let's Take a Ride
The original BMW Fuel Pump / ECU Combination Relay used on early L-Jetronic BMWs is becoming increasingly difficult to find—and in many cases is no longer available.
Even if you manage to locate a "new" old stock relay, it's still an electronic component that may have been sitting on a shelf for 40+ years. Age alone can affect reliability, leaving you wondering if you've really solved the problem.
When the original relay fails, your car may crank but not start, the fuel pump may not run, the engine may stall intermittently, or you may experience a variety of frustrating fuel injection issues that can be difficult to diagnose.
Satisfied Incorporated has developed a modern conversion kit that replaces the original Bosch combination relay with two common automotive relays while duplicating the function of the factory relay.
Everything you need except solder and heat shrink tubing.
This kit requires cutting the factory relay wiring and soldering the supplied components into your existing wiring harness.
Basic soldering skills are required. If you're not comfortable soldering automotive wiring, installation by a qualified technician is recommended.
Rather than relying on an increasingly rare and expensive combination relay, this conversion uses standard automotive relays that are inexpensive, easy to source, and available almost anywhere.
If one of the relays ever fails years down the road, simply replace it with another off-the-shelf relay instead of searching for a discontinued Bosch combination relay.
This conversion was developed through extensive testing to duplicate the original relay's operation while dramatically improving long-term serviceability and reducing future repair costs.
Compatible with many early BMW L-Jetronic vehicles using Bosch Combination Relays:
Common applications include:
Additional applications may include other early L-Jetronic BMW models. Please verify your Bosch relay number before ordering.
