Megane II check injection but no error code!

[karllap]

Hi, We have a 2008 1.5 megane that has the check injection error. It comes on as soon as we start the car and doesn't go off. But I have out 2 code readers on it now (only DIY ones, not proper garage ones) and both show that there are no stored codes.
I appreciate that they are only the cheap code readers but I have used them on mulitple cars including previously owned scenic's and megan'es and it always seems to work.

Does any one have any idea's what the issue may be?

I'm afraid that your little OBD reader will be totally useless when it comes to diagnosing Renault injection faults. I discovered this the hard way! luckily I had access to very expensive instruments for without a diagnostic reading, it will be impossible to say what is wrong with your car. Suggest you try your local garage and see if they have a good reader. Most will have at least a Snap-on tool or similar. Even connection via elm327 interface on a laptop is useless.
The subject of code readers has been covered before on this forum (by me and others!)

Thanks for the reply, I had a feeling it would be something like that but the weird thing is I have used that specific code reader on meganes and Scenics before although they where 2003, 2004. This is a 2008.
