Hi everyone.

i have a Mazda 2 diesel 2008. I got the injector replaced not so long ago as it was in limp mode and wouldn't go over 20mph.

But now turning my car on there's an amber engine warning light on. With no other issues. Drives fine. No smell of diesel literally absolutely fine. I've cleared the code (naughty yes I know) but it's come back. And now I have my MOT in a few days. Again yes I know I've left it late but I read that it could go away.
any help??
thank you!!

Whats the code? Do we just guess?

 

If we have the DTC code, the Mazda workshop manual has a useful diagnostic section that could help you or us narrow it down.

 

Not sure is "narrow it down? is the best phrasing. A single DTC gives you options to start a systematic testing, but you should consider a single DTC and what it basically relates to and know other area's that could have supported the triggering of that single DTC. There is more information in the ECU to help diagnosis a DTC. The FSM (Factory Service manual( does not tell you the other steps because they assume that the person using the FSM is at least trained and educated in Diagnostics servicing.
