For those that have recently done a performance upgrade (i.e. K&N Filter, Iridium Spark Plugs, Exhaust, etc, etc), an ECU reset/reprogram is advisable. 

By performing a reset/reprogram your ECU will self adjust to give the proper air and fuel mixture for your engine which in theroy will give you the best fuel economy based on your upgrades. 

Here is how to do it: 

1. Start up your X-Trail and allow it to warm up to its normal idle. 

2. Next turn off the engine. 

3. Locate the fuse box located under the bonnet and next to the battery. Pull out the 3 fuses: ENG CONT1 (15A), ENG CONT2 (10A), ENG CONT3 (20A). Refer to the pics below. Keep the fuses out for at least 5 minutes. This will cut all power to the ECU. 


4. Plug the fuses back in and close the bonnet. 

5. Start your X-Trail making sure NOT TO TOUCH THE ACCELERATOR WHEN YOU START IT UP. This is very important. 

6. Let the X-Trail idle at its normal idle speed for about 4 minutes, then turn off your engine. 

7. Start your X-Trail again and you're done.

Enquiries regarding this type of repair are welcome.
