Engine warning light.
« on: April 08, 2019, 10:48:28 AM »
Having problems with the egr valve (juddering at low revs). I read on here that if you unplug the egr valve it helps with the judder. I did and it has.

The yellow engine warning light has since come on. Is this because of the disconnection and will it go out when plugged back in.

Thanks.

Disconnecting the EGR will put the engine management light on because it can no longer see the position sensor in the EGR valve.

If you reconnect the EGR, it should go off after a day or so of normal driving.

I took the egr valve off, hoping to see it carboned up. It didnít seem to be, so I just periodically sprayed egr cleaning spray into it and where it attached to the engine. Had a little play with the valve and sprayed in there too. Left it overnight in a bit of a pool. Refitted with a new gasket and it seems to have cured the judder. Iíll not get too excited as Iíve read that it could soon return.

Iím getting into this diy car repairs.
