Hello,

First of all I am sorry for my bad English

I have a strange problem with my "Mazda 3 (2004) 1.6lt. (109hp) diesel hatchbag".

Actually everything is fine but from time to time every 2 or 3 days this Check Engine Light is lighting up. Usually what I do when this happens is just turn off the engine and start it again and everything works just fine the light turns off and the car works fine for few more days but than again the light is coming up. Even when the the light is turned on there is no any problems.

Rarely it isn't happening for week or two but than again. The problem first started about 7 or 8 months ago.

We have tried to read the error with multiple OBD devices but no result, there is only one error and it's related to airbag and nothing related to the engine itself.

Anyone faced similar problem before?

Also I noticed that it is mostly happening when while climbing or when I enter a rough road. This makes me thing it's related to a vibration but don't know.

Thank you in advance.
