Frequently Asked Questions

Which lights will the R5/FCX tools reset?
The R5/FCX scan tools will reset the check engine, service engine soon, oil service, inspection and maintenance mileage indicator lights; it can often reset other lights by association. What that means is there are other systems in the car that check the health of the main ECU (also called a DME), if the DME's have a problem then the light for the other system also comes on. For instance the automatic transmission light will come on when there is a sudden fault in the DME. Resetting the faults in the DME, which also reset the engine light, will bring the DME back to normal status and all systems monitoring it. The R5/FCX tools will not reset your brake lining light, ABS brake light or the SRS airbag light. We carry the R5/SRS tool for resetting your airbag light.

What is the difference in a Peake R5/FCX and a generic OBD II type tool?
The R5/FCX is not an OBD II device, it is a BMW specific factory-code scanner. Meaning, it reads the full range of detailed BMW factory codes (which are the same codes the dealer has access to.) In contrast, OBD II tools use a government-mandated, generic code language, and do not read any BMW factory codes. OBD II is not inherently bad, but for BMWs and other European makes, OBD II tools suffer significant limitations. The two most common complaints about OBD II are (1.) "unknown code" messages, or misleading codes that prompt unnecessary replacement of perfectly good engine components, (2.) a OBD II device would not reset the service reminder lights.

The R5/FCX resets the BMW oil service and inspection maintenance reminder lights. OBD II tools absolutely will not reset those, as they are manufacturer specific, not generic. Also, if your BMW is a 1995 model or earlier, you will require the R5/FCX II. As OBD II devices are simply not compatible with BMWs of that era.

What tool should I use for my year/model BMW?
We created easy to understand compatibility pages that list all the year/model BMW's for each tool. If your looking for a tool that will scan and reset your check engine light, service engine soon light, oil service - inspection lights & service mileage please visit our FCX Compatibility Page. If your looking for a tool that will scan and reset your SRS airbag light please visit our SRS Compatibility Page.
How do I know what the error codes mean?
We supply a code definition book with each R5/FCX II, R5/SRS and R5/EMX. These products have a small, two-digit display screen that displays the fault codes (example: tool shows "F6", simply look up "F6" in the user manual to see the meaning of the code.)
What is the difference between the R5B and the R5/FCX II?
The R5B only resets the service reminder lights known as oil service and inspection lights. The R5/FCX is much more capable. Of course it will reset the oil service and inspection Lights, but its main strength is its ability to read and display all engine codes, and reset the "Check Engine" and "Service Engine Soon" lights. Visit our Product Info Center for information regarding each product.
Should I buy the R5B oil service tool or the R5/FCX II engine scan tool?
Most people who order the low cost oil service reset tool end up buying the R5/FCX II later. Why? Because check engine lights (also known as the MIL or "service engine soon" light) are simply unavoidable in BMWs. Unless you have the R5/FCX II you are put in the position of relying on or paying a repair shop or local BMW dealer to read the codes, but usually at a cost of about $100, which is the price difference between the R5B oil service tool and the R5/FCX II. Sometimes you find out that the MIL was on for nothing more than a loose gas cap. But, when faced with a large, hard to understand repair bill and overly technical explanation, it becomes clear that the extra money for the R5/FCX II would have been money well spent. Scan tools are popular for a good reason. People who think that code scanning is too technical have not tried the R5/FCX II, using one compares in difficulty to checking your oil or putting gas in you car! And for the shop techs reading this, you probably already know that if you cannot read a customers error codes, they will be forced into your competitor's shop.
