I can’t see what an EGR software update is going to do for an EGR valve that is probably partially seized open and a cooler that is probably heavily fouled.
If anybody knows the reason for software change it would be good to know.
So after applying Google Translate to www.wnwalt…… it seems that the software change is to increase the period the EGR is in operation for legal reasons. Given that most vans on the road over a couple of years old are probably suffering from coked open EGR valves is it going to make a difference.
And indeed, there are fairly recent software updates for CFCA ECU variants
Just to name a few...

The same seems to be true also for the other T5.1 engine variants CAAA, CAAB, CAAC, CAAD, CCHA.
Watched from the window, van was up in the air and the cover was off, sump plug out......drained from belowWill ATS be pulling the sump cover off and drain plug out to get the last 0.5- 1L? Somehow I doubt it, just vacuum pumped out from the dipstick port to save time.
I was a bit worried but now after reading the translation of this, I am really crapping it!

I certainly wouldn’t be making this change to my van, even more soot re-entering the engine causing contamination and wear.
I just did mine today and it was a massive pain in the a. Right pipe took 10mins, the left took 3 hours. Someone must have changed the egr cooler under warranty as the left top and bottom screws nearest the radiator were cross-threaded. Managed to sort the top but the bottom was wrecked as the thread in the aluminium egr cooler were stripped. Luckily, the thread goes deeper than the screw so made up a longer one with a nut and washer for tightening. Test drive for 45miles was fine; the van even feels more responsive now. Can't say as its exactly discreet though as you can't hide all the cabling to the Tafmet.I had a lot of trouble fitting the blanking plate on the left hand pipe, the one with the awkward to access screw. There is little to no give in the pipe and I really struggled to open up a gap large enough between the pipe and the EGR cooler to fit the plate. Did you experience the same problem? Maybe I missed loosening something somewhere
Have you removed the flexi pipes to the egr then?I have installed the engine and battery covers. If the mot tester knows what he’s looking for he may spot two link pipes missing.
Yes. The Darkside Dev blanking plates were too thick to slide in and retain the pipes. I’ve considered getting the pipes welded/blocked off and refitting them so it looks OEM. Just not gotten round to it. Mot due September. So times ticking.Have you removed the flexi pipes to the egr then?
You can make it discreet with careful routing and use of alternative matching harness tape.Can't say as its exactly discreet though as you can't hide all the cabling to the Tafmet.
Plenty of stainless steel shim and gasket sheet available on ebay, very easy to make your own.Yes. The Darkside Dev blanking plates were too thick to slide in and retain the pipes.

My advice is once you see oil consumption the wear has already started so fit a Tafmet kit now. No need to map anything.I have a 2016 180 biturbo DSG has covered 66k I have annual service and oil change, the van does not use any oil to speak of and have only topped up once when near it's service.
I have checked the label on the EGR cooler and it is the revised one but from the horror stories here it would seem so far I have been lucky, I am now thinking to get the egr blanked off will this have any issues regarding MOT just had an MOT and the readings were low. I will need to get someone to delete the EGR from the ECU correct?
My van is Euro 5 and was a month out from being a Euro 6 which never bothered me but Mr Khan's expansion of the ULEZ is going to be a factor soon as I am sure other cities will follow. I did hear somewhere that it could be possible to get the van recalibrated through DVLA (is that Bullshit) The Mot tester said the emissions from my van were the same as the allowance on some Euro 6 .
The van is due it's annual service now, should I get the garage to give me some of the old oil to get an analysis, how much do you need?
Thanks
I don't believe the CFCA was ever a Euro 6 and ever had AdBlue did it? So regardless of dates, your vehicle wouldn't/couldn't be EU6 at a later date.I have a 2016 180 biturbo DSG has covered 66k I have annual service and oil change, the van does not use any oil to speak of and have only topped up once when near it's service.

Order a Millers kit direct from them. Put in 75-100ml of old oil and post it off. You'll get a report back within 5 days usually with the state of health of the engine. Key watch out is high aluminium content which will trigger concerns that the EGR cooler is breaking down and ally oxide is entering the engine. Regardless, I would recommend having the EGR blanked off at both ends and use piggy back Tafmet solution as DXX proposes. Other route is mapping out, but needs a specialist which is the route I took. Tafmet is DIY and overall cheaper to do.
Your recent MOT and emissions readings have nothing to do with the EGR degrading. That's unless the engine wear and oil burning was at such a level litres of oil are being burned through the exhaust pipe.
Fingers crossed all remains good for us all.
I followed the general advice above. The oil change had been done and the van driven 315miles before I fitted the EGR blanking and the Tafmet. I've now done 897 miles since the oil change and EGR blanking so I took a sample today and sent it off to Millers for analysis. They ask you to fill the bottle which is 80ml. You will get the results back via email. Hopefully, I will get good news......The van is due it's annual service now, should I get the garage to give me some of the old oil to get an analysis, how much do you need?
Have you blanked the EGR now? If this is the first oil analysis then 3k should be plenty to give you a baseline of wear and possible EGR failure. Your oil consumption may be down to other reasons such as turbo seals.At 3k on the current oil I will do the same. Its had three oil and filter changes in less thn 3k miles, and I have to top up quite a bit when driving loaded. I have a oil analysis kit here so might do it after the summer of big trips.
I am deciding on either cut-and-run next spring and add a further £20-25k and buy a ULEZ 2016+ or go new VW create engine with Retro Resus for £10k in my great condition 2014 van. My other concern is I want another Caravelle dsg 4motion so its going to be another BiTDI (204) that might have the same issues...
