emssions workshop dash message

[JimC64]

Hi guys,
just had a call from the wife on her way home who says as follows......

driving along and EMISSIONS WORKSHOP message displayed on the dash along with ECU light ( reading between the liner here, you all know how they descirbe the orange thingy etc ......doesn't make it easy )

Anyhow I've told her to drive home being careful and we'll see from there....

Having checked....it could be a faulty EGR valve or it needs cleaned possibly?
Lambda probe?

took it for an Italian tune up and booted it up an down a free piece of road and it seems to have cleared for the moment.
I've always said the wife drove like an old woman and this proves it..

Any ideas / suggestions please??

TIA

Jim

A fault code read to see which codes(s) is stored.

I had same about a month ago although I don't remember if the EM light came on. Lots of threads pointed me to the coolant sensor, under a tenner on fleabay and not too bad to fit. Vagcom scan confirmed the fault before I bought the part. All ok now.

Hey there......can anyone help with reading fault codes?

Still have this issue at present. It seems that when allowed to warm up and using the "Italian tune" up method that the light goes away for a short while.
MAF / Coolant sensor likely culprits?

TIA

UPDATE - For what its worth, this is where I'm at......

Had the car serviced in Sept last year by Arnold Clark, but decided to poke around a little on my own today.

Started with the air filter and WOW is all I can say. On opening up the air box there was a fairly hefty amount of leaves / debris / dust etc in there and the filter was awful!!!
The car has probably only done around maybe 5k in that time, if that and mostly motorway, and always driven easily.
Anyway, I removed the filter and thoroughly cleaned the housing removing all the crud and replaced with a new filter.
I also added some Redex to the fuel to help in cleaning the injectors as well as some STP additive into the oil.

Its early days, but after more than a few miles nd several stop / start / stop cycles the warning light has failed to reappear so far

Anyhow, for the moment its running quieter, sweeter and much more smoothly than before with no "EMISSIONS WORKSHOP" warning light........here's hoping.

If there's any change I'll repost of course

Further update >>>> It seems that cleaning the EGR valve on this occasion did not fix the issue as it came back and the dash warning light intermittently appeared, so back to square one!
I certainly believe that cleaning the EGR valve was helpful and a worthwhile exercise for future reference.

Not having VAG-COM I turned to the next most likely culprit ( in fact probably what I should have done first tbh ) and that was the temp coolant sensor. I got it off Ebay for around £6.00 and that included the O ring and the horseshoe retaining clip.
Just outta interest I called the dealer who wanted £34 incl of Vat but that was for the sensor only. The O ring was a further £1.34 + the clip was extra too.

Anyhow the temp sensor was changed by a local mechanic friend of mine......Its located just under the EGR valve but is kinda hard to access.....All in took around 30 mins and £10

Total for the fix was £16.00
I have a funny feeling that the dealership would have been in the region of £250 - £300 to diagnose, then supply + fit incl of labour + vat so I'm well chuffed
