EGR blocked again

[JDC]

VW will not replace an egr until they have done 5 flushes, I’ve just had my second flush in 2 years (2018 65k miles), I’d try the flush route first and see how long that lasts

Is that via the Vw warranty. Mine went in March and i got it replaced. I wasn't offered it to be flushed. It's a 16plate.

It’s the extended warranty, first time they flushed it back in 2022 they changed the front pipe to a new design and flushed it on good will, this time yhey said VW wouldn’t do it for nothing but where helping out with a good will contribution. I know many feel dealers have them over but I’ve generally had good service from VW Croydon, the service manager is pretty open with me and I guess being in London they are seeing a lot of commercially owned vans doing short journeys so egr problems

Also, you guys who have had deletes. How long have you had the mod for? Euro 6 engine? Any dpf issues since?

Cheers

You might find the two posts I’ve attached useful….

Please bear with me on this, I know it looks a bit long-winded, but I think it’s worth having a bit of background detail….

My van is the EU6 102 engine with adblue.

Sometime in June the dreaded flashing coil light made an appearance one afternoon when I’d just started the van and I was leaving work! During that journey to drop something off the van was running on limited power. When I restarted the van, the fault had disappeared and all was back to normal for my journey home…. and to be fair, I’ve had no faults since, but after reading the endless nightmare stories on this forum + previous personal experience with a blocked/failed EGR valve, this got me worried that it might be EGR problems?

I contacted @Dav-Tec (Chris) who by now had done a number of very successful jobs/upgrade’s on my van to see if he could work his magic with a possible EGR delete? Unbeknown to me, @Texxaco (Pete) had been having similar issues with his stunner of a T6 and had already had the @Dav-Tec treatment in the way of a EGR and ADBLUE ‘solution’!

At the T6Forum summer camp meet in July, Chris kindly scanned my van and found that the fault was actually with the adblue system and not the devil’s work EGR as I’d suspected…. either way, I wanted the EGR sorting! So I got booked in with Chris to have a custom remap which would include the same EGR and adblue ‘solution’ as Pete’s van.

On the day of the remap, Chris did a scan as he always does prior to any work…. goes through any fault codes with me and when looking back at previous scan’s, Chris discovered that this adblue fault had history and was showing up on most of the previous scan’s. I told Chris as well that I’d very recently noticed the smell of diesel fumes on startup…. not necessarily in the cab, just in general around the van and when we went out on the first data logging run it was clear that something wasn’t quite right?

When we got back to Dav-Tec HQ, Chris found that the rear EGR pipe was split and exhaust gases were p#ssing out into the engine bay and this was causing the boost pressure problem. No problem for Chris, he removed the split pipe, fabricated a couple of ‘delete’ plates from some sheet steel, refitted the lot and we went out on another data logging run. Much better (near perfect) results meant that a new custom map could be written to include the EGR ‘solution’ and away I went.

I’ve been driving around with the new map now for a week…. to and from work and the usual runs and roads so that I could get a comparison with what I had before (which by the way was a generic Pendle map installed by Leighton Vans). Don’t get me wrong, I had no complaints or issues with the previous map…. I’d had it on there for over two years, but because of the running issues, I needed a ‘solution’ and Chris’s custom remap ticked all my boxes.

I couldn’t be happier with the results of the custom map supplied by Chris…. the engine runs free and smooth even from a cold start up and pulls progressively, purposely and smoothly throughout.

I want to thank Chris for going above and beyond as he always does…. and also his very patient wife Tracy for putting up with me on that Saturday!

Cheers, Matt

Just wanted to give a quick update on this previous post….

Recently I took my van for a service and MOT (this being it’s first MOT since the above EGR and ADBLUE ‘solution’) and I’m happy to say it sailed through the MOT with no advisories at all…. just a nice compliment on my van from the MOT inspector.

I’m so happy with the work that Chris carried out with this remap…. my van is running the strongest and best it ever has…. and another massive plus is that the MPG is definitely much improved! Not that I have any scientific calculations or figures for you, but just to say that my ‘miles per tank’ are always very close to 500 miles per tank now where as before it was always nearer to the 400 miles.

Thanks Matt, I’ll check the posts

I think I’ll go for the swap. Use an additive. And if the the Egr fails again after 14k miles I’ll map it out. and probably not go for the upgrade in torque.

I would definitely get it mapped out…. you know for sure it will fail again…. look at your thread title!

I also use the Millers Diesel Power Ecomax additive in every fill up…. I have done for years, on this van and a previous pickup truck.
