EGR Valve noise
Probably been covered many times and I should have used the search,but here goes anyway.

I have a noisy EGR valve on shut down, and when touching the throttle at low revs.
My question is, if I change the EGR myself do I need a fault code reader to set up the new valve?
I have not had any MIL light at present and truck driving as it should.(2007 90)

Any help gratefully received .

Nick.

The EGR valve doesn't need any setting up, but there may be stored DTCs even without the MIL illuminated. Clearing the DTCs is not essential but would need a device of some kind.

Thanks for help and quick reply will give the replacement a go myself.
Need a code reader so will purchase a cheap one.

Thanks again

Nick

Nick, I have one that I have spare if you need one. (Cheaper model)
And as Blackwolf mentions, he's hit the nail on the head there.
If your EGR is making noises that weren't through normal running it's likely on its way out, it will flag the MIL eventually if not replaced.
Alternatively you could pop down to mine, I'm not a million miles away.

Thumbs Up

Thanks for the help, just come back from a mates who has a snap on diagnostics kit and he reckons it will do the job.

Going to order a new EGR and have a crack at replacing it before it lets me down.

Cheers

Nick

Same symptons here, been considering replacing the EGR as well.

How good are the ones found on EBay? Most seem to be from the same supplier...

One last note, in my case, it looks like premium fuel with additives make the EGR louder, whereas regular diesel with 2SO helps make it quieter...
