Hi all, what is the best diagnostic software for my 04 impreza? I need to diagnose why the engine management light is on.

Thanks

 

elm bluetooth adapter for £7 of ebay. Torque App of Android store £3.

it will read ecu tell you what the fault code is. you can also clear the fault code to see if it returns

from this you can then determine what is potentially causing the fault code to display - for example if it says o2 sensor issue, dont automatically assume its an o2 sensor fault, it could just be reading high to an overfuelling issue etc!

 

I recently had the same question. I bought a decent obd11 on eBay for £30. If your near the north part of London your welcome I can use mine on your car to show the fault code.

 

Ive got an elmscan 5 it's good and you can data log, test quarter mile, dyno etc except you need a laptop

 

The torque app seems good but does it have all the uses of say like vagcom does fo the VAG group as this is what I am used to using on windows.

zorba999 which one did you buy?

Mark7wrx does this eanble all fault code diagnosing and clearing?
