I have noticed that this light has popped on for about 1 sec twice in the last week. I have checked the water etc - ok.
Is there anyway I can trace the potential fault or is it better to take it to a garage ?

 

Try this web site:- http://www.geocities.com/subman2001nz/ and goto the "Reading ECU Codes" link.

Check the MRT web site for instructions on how to display & read error messages stored by the ECU.
Basically join the two connectors under the dash near steering column & count the number of flashes, both short and long.
