Engine Light on 2001 Peugeot 406 2.0 diesel

Post by lveale »

Hi all

I have a 2001 Peugeot 406 2.0 diesel that the engine light is on on. The car drives fine and I have done several hundred miles in it since the light came on so my understanding is that it's likely to be emissions related?

The exhaust has just been replaced on it but there are no sensors on that anyway so that is obviously not the issue. The diagnostics port doesn't work with any readers that I have tried (I guess it needs the peugeot planet software?).

It's up for mot soon and the garage tells me that the engine light being on is a fail.

I wondered if anyone has come across this issue before and if there are any common causes for it that I could check?

Thanks in advance!
