Mysterious EGR light ?
 

I know that the D24 in a 1984 Volvo 240 Diesel does not have an EGR so why do I have an EGR light on? When I hit around 91K it came on. I have been driving around with it on for months now and have no idea what the reason for it is . Do any of you have ideas? I have not been able to find any info on line about it either. When I get some spare time I would like to trace the wire that goes to that light and find out why it is on. I did however have some fuel cut out issues today which I'm hoping was just water in the fuel filter , which I have sense drained. If it's not then it must be the solenoid issue in the fuel pump and I will need to source a new solenoid .

I have just bought a 94, 945 d24tic it has an egr

Can you post of a photo of what it looks like on these engines ?

I'm to dumb to upload a picture her. So I made a gallery under my user

So my NA 1984 D24 has nothing like that on the engine .

I'm just going to have to trace the wires when I have enough time .
Thanks for the photo!

Yeah no EGR on any D24 engine, only on D24T.

Some gas 240s had a system called Pulsair that involved EGR and my guess is that yours has that light for use with that system, and something's causing it to illuminate for an unknown reason. IIRC some of those cars had a mileage counter, reading off the speedo, that was set up to turn the light on every 30k miles to remind the owner to get the EGR system serviced. Maybe your car ended up with one of those counters somehow despite being a diesel and not having any EGR?

If you want to check for that, look up under the driver's side of the dash, behind and below the instrument cluster, and see if there's a little black box, about the size of a deck of cards, with both electrical cables and a short mechanical speedo drive cable coming into it. If it's there, unplug and remove it and see if it turns the light off.

If not, you can try to trace whatever's causing it to light, which could be a wiring short to ground somewhere, or a fault in the cluster internal wiring, etc...

Or just remove the bulb for the EGR warning light. ;)
