After a flush
That’s poor. It’s not practical due to the labour but it’d be interesting to see inside the cooler after a flush to see how effective it is.
Out of sheer morbid curiosity, I used a chemical cleaner on the old EGR pipe and it got it back to shiny metal again. Was going to clean out the old cooler aswell.

Was it easy to do? Possible to do on the driveway?
I cheated and got @BognorMotors to do it. I guess it’d be possible on the drive. The front needs to come off into the service position and the coolant needs drained. The VW service doc recommends depressurising the fuel system also. There’s a guide on here somewhere. Weirdly just replaced the EGR on the wife’s A4 today, and I did that one on the drive!

Did you get this resolved. Did you have to pay for the new valve and what did it cost in the end?
Yep, That's my experience of VW(UK) also.
; albeit many moons ago.
mine has been into VW several times over the last 18mnth, sometimes for weeks at a time!
this week it's back in for the same issue. However before I put into VW, I got RAC to look at it as the EML issue was annoying, 2 mins under the bonnet at the guy says the EGR link pipe is split which is causing the EML light to come on as it's reducing flow. His words were " why VW mechanics never noticed that I've no idea" it's weird as I've always heard the pluffing of air, but I'm now mechanic.... saying that, maybe I'll get a job as a VW tech!!
After I showed VW the photo they claim It must have just happened, anyway, that's been replaced now. They now say I'm losing coolant, at a rate i should be topping a litre every couple days as the pressure test is below the recommended BarG. Although I've never topped it up, and no warning lights... Oh and it's just been serviced by them..

Interesting. I posed the same question back in June as that was my theory:
EGR flexi-pipe: Exhaust Fumes In Cab, Hissing From Engine Bay.
Well, I've now joined this particular club. Exactly same symptoms as above, first noticed the whooshing air leak sound, slight smell of fumes inside. I'm mainly motorway miles, but am always noticing regens when stopping at home these days, after ten or so miles of town driving. On hold for VW...
My other thought is that this causes a boost leak, which means it runs rich, which will create more soot and more regular regens.
Also, the EGR reduces combustion temperatures which in turn reduces NOx (same pollutant as Adblue reduces), so a poor EGR means the AdBlue has to work harder. My EGR leak used to sometimes manifest itself as an AdBlue fault as the NOx was out of tolerance.
They all seem to be related.
Well got my bus back yesterday. Another egr flush, last one was 26th August. Less than 1500 miles and the light came back on after 7 weeks.
Also they discovered an oil leak from drive shaft seal and some of the trims underneath were smashed (wife likes splashing in the big puddles).
Let's see how long it lasts this time.

Wow that just nonsense ,they either did a piss poor job in the first place or you should have a new egr fitted .its now £300 for a flush imagine if you were paying that every 1500 miles .
Has anyone used carbon clean for this ?they claim to be able to clean the egr as part of a 3 stage flush .

Is there any way you can self clean. An additive or whatever. My dealer told me a i needed a flush when they looked at the fault codes. When I queried it they checked again and said no it was fine but now i'm paranoid.
I may have a skiing trip to Switzerland next week in it and if I can flush it myself then I will.

Dont think so ,you could try an additive but I dont think the VW flush is that good so I doubt a bolt of Forte will clear it
That’s good news. What’s the age/engine in yours? Was this a warranty repair?
