Your car within warranty? Is your "check engine light" on? Does engine smoke a lot, black or white smoke? Have you checked/replaced your fuel filter?
there is no check engine light. fuel filter was replaced about a year ago when i did my 10k km pms.

This is possible if the fault is intermittent. Fault may not have been active when you visited casa. got it.

Correct, GDS is their scan tool.
