For 2002-2006 R50 Cooper and R53 Cooper S Hatchbacks, and 2005-2008 R52 Cooper and Cooper S Convertibles...
This procedure is intended for a basic 'reset' of the ECU. It is not for clearing error codes or turning off CEL (check engine lights). Proceed at your own risk.
How to Reset the ECU:
Here is a list of all the tests on your MINI:
1.0 Chassis number
1.1 Kilometer count
1.2 Parts number
1.3 Coding-, Diagnostic- and Bus-index
1.4 Production Date (Calendar week/year)
1.5 Hard- and Software status
1.6 Injector status, Cylinder count, Engine factor.
2.0 Comb system Test
3.0 Service interval counter
4.0 Actual fuel consumption in l/100km. eg.0154 = 15,4 liters/100kms.
4.1 Consumption in liters/100kms.
5.0 Distance consumption in l/100kms.
5.1 Actual rest distance with available fuel in Kms.
6.0 Actual amount of fuel in tank. eg. 123321 =12,3liters left 32,1 liters right
6.1 Total amount of fuel in tank.
6.2 Show value of Fuel gauge.
1= both senders OK, 2= sender failure, 3=ti signal implausible (no reading)
7.0 Actual coolant temp.
7.1 Actual outside temp.
7.2 Actual engine revs.
7.3 Actual speed
8.0 Hexadecimal readings of menu 7.0 to 7.3
9.0 Actual on board voltage (Battery)
10.0 Land codes
11.0 Unit codes
12.0 No function
13.0 Gong test
14.0 - 14.4 On board diagnostic codes. eg 000000 = no failures
15.0 - 18.0 No function
19.0 On/Off for Test menu.
20.0 Correction factor for Fuel consumption Formula for correction:
Shown consumption x 1000 / user defined consumption
Push the trip reset button to begin the correction. Numbers count up from 0-9, when correct number shows push trip reset button.
20.1 Sets 10ths. for consumption factor
20.2 Sets 100ths. and 1000ths. For consumption factor
20.3 saves the new consumption factor and shows new value
21.0 Software reset. (Same as disconnecting battery)

I had some work done and I'm getting a code for a sensor I replaced it now check engine light is on when I use my scanner the light will go off once I drive the car once again the light comes back on any suggestions.
Mini Mania: Sounds like there is an issue with the sensor triggering the check engine light that needs to be corrected...
