Of course you should change the TPS mate!

Your xtrail is now running in limp mode (fail safe mode) and it shouldn't be driven until the throttle position sensor (TPS) is replaced.

You said the ECU gave an error that the TPS is faulty, so if you want to be sure, ask your mechanic to give you the exact error code he's seeing on the scanner when he connects it to the ECU and post the information here.

Just bad luck mate, the TPS has been found faulty on many other xtrails in Australia too.
