For months now I have had the EGR blanked off but every week or so it would throw up the EML light! Not a problem but annoying.

Anyway, the light had been on for about 6 weeks before I decided enough was enough and reset it. But about an hour before I did so the light went out itself! I first thought oh dear it's a bulb, but it wasnt as it still illuminates when you first turn the ignition on.
The light has now been off for a few months with no issues at all. So it looks like my ECU has finally taken the hint!

Just tought is share my experience as I know it's a common issue with the mk3 euro IV

Great new stef,
I was going to be the fool and post " aw huh the blubs blown"
But you stole my thunder by confirming the bulb is in blown :)
Good to see its sorted itself out.

You did use a stainless steel blanking plate didn't you?
Aluminium blanking plates break through after a period of time.

Yeah, my car could be the one that never learns - or maybe that's the driver.

Yep Lenny it's 3mm stainless plate without the hole (why do people drill holes in them!)

Good man ;)
Some drill holes to prevent an EML but it defeats the purpose of blanking it,
It needs to be 100% blanked otherwise don't bother your !Removed! :lol:
Especially an aluminum blanking plate with a hole,
The pressure going through the hole will split the plate on the first 30 minute motorway drive.

Never knew an ECU could suffer from depression in the winter months causing it to cut back on potential
