A ‘Service Engine Soon’ light on the dash of your Mini Cooper (and Mini cooper S) can certainly take the fun out of your day. To quickly and accurately diagnose the problem and reset the warning light, you need a code reader that can access the fault codes specific to your Mini. This requires a NON-OBDII tool, such as the low cost R5/EMX from Peake Research, which will read and reset factory “dealer” codes and reset Mini’s unique dash lights, like the Oil service - Inspection and engine lights.

Why is "NON-OBDII" so important?

There is a huge difference between OBDII codes and the highly specific “factory” codes. The R5/EMX accesses Mini’s vast array of “factory” diagnostic, analysis and repair codes enjoyed by Mini dealers, where OBDII tools and the misleadingly named “Manufacturer Specific OBDII” tools simply will not. Keep in mind, BMW/Mini did not go beyond the government’s most narrow and basic legal requirement for OBDII code reading in their cars. Therefore OBDII code readers are of virtually no value outside the realm of smog testing.

If your aim is to reset your Mini’s unique brand of dash lights, repair, pinpoint and analyze, there is no substitute for “factory” capable tools like the R5/EMX made by Peake Research Corporation.
