Ummm... I think you have ended up with a duffer mechanic. Xetas have a problem with that Check Engine thing. Two things buddy. One, even if a problem came for a split second that Check Engine will remain. This has been done in recent cars so that people immediately visit the service station and get it checked lest it aggravates. Most of the time they hook up the car with their comp which then starts checking parameters one by one and either oks them or flags any problem. After its through the error has to be explicitly cleared. The system asks whether the logged error should be cleared. If that is not done the car will keep flashing that Check Engine message irrespective of anything else done. So check whether he remembered to clear the error.

Now what could cause a split second problem that causes the flash but later on the computer detects nothing? After talking to a few Xeta specialist (one of my friend's new Xeta was showing this problem once in a while but nothing used to come out when hooked on the system) I realized that to increase the FE Indica runs a real lean mix. ECU and the engine has been tuned accordingly. However because of these it is also very sensitive to fuel adulteration. If any of the injectors feel choked for a split second the ECU flashes the check engine. By the time you reach the service station most often things are back to normal and system does not catch any problems.

My friends problem was solved when he chucked the pump next to his house and shifted allegiance to a well reknowned pump, albeit a bit far from his residence.

P.S. One technician told me that sometimes it can even be caused because a small few microscopic particulate matter entered one of the injectors from the tank. You can not even call that fuel adulteration.
