Fault in car emissions systems light on

[Pauld]

Hi

As per the title, the engine light is on, it came on a few days ago and then went off again.

But now it is back on.

Any thoughts.

Thanks

If it's the emissions warning light, then that happened once to me with my p2 V70, and it turned out to be a broken barcket on the exhaust which was allowing it to move more than normal. It was the rear most bracket that had broken. Hope it's something simple like that as you just buy a repair bracket!

Yeah. Get a code reader and read the codes. Note them ALL down. Clear codes and drive for another 50 miles. Re-read codes. Note codes that are now present and address what ever they relate to.

Simples!

Now lets not have any nonsense replies...saying it could be this and it could be that. All you gotta do is what i've just said. Nobody in this forum or any other can say what it might be. It could be hundreds of different things and i ain't kidding!
Let us know after 50 miles what codes were read and then we can start to help you and point you in the right direction, until then we are ALL clueless :)

well?????

Had the codes read a second time, the same fault.

Changed the Fuel pressure sensor, see other post.

I think that has sorted the problem, and it is running better too.

Fingers crossed!
