BMW E30 Gauges & Miscellaneous

What is the Check Engine light trying to tell me? The BMW Check-Engine light can mean any number of things.
Sometimes it's alerting you to the real need for a repair, but most often it is merely indicating one of the many, simple (top off your coolant, loose gas cap or oil cap) type problems. Imagine paying a hundred dollars to a repair shop to tighten your radiator cap and reset the Check Engine light. Without the R5/FCX, you're stuck staring at your Check Engine light until you see the mechanic who can reset it. Routine Maintenance Lights - As an added benefit, the R5/FCX includes the ability to reset the oil service and inspection, routine maintenance lights. Considering that an oil service for a BMW can sometimes equal the price of the R5/FCX, this feature alone is worth the price of the R5/FCX. Manual and Code book included.
No more driving around with those lights on! Do you change your own oil or go to a fast lube? If you do, then the R5 reset tool is made just for you. The R5 gives you the freedom to reset your own Oil service/Inspection lights, allowing you more choices in service. Super easy to use, takes 15 to 20 seconds, and you don't even have to get your hands dirty! Includes Instructions.
