Viable way to do EGR delete?

I purchased the van new in 2016 when I retired, mainly to carry my dirtbikes, but also as a daily driver when my wife is using the car. It has full VW main dealer service but has only covered 32000 miles to date.

Unfortunately, it has been used for lots of short journeys (but also lots of longer ones as well) and I now have a EML on, flashing coil light and van is in limp mode. I have taken it to a large reputable indy who has run the diagnostics and said the EGR is sooted up and needs replacing at a cost of £1268. They wont do the EGR delete.

There is a smaller, more local garage to me who has said they can do an EGR delete by re-mapping the electronics and then unplugging the connection to the EGR when the valve is in the closed position thus negating the need for blanking plates - cost £180. If I have the cheaper delete option done, will the rest of the exhaust functions still operate as normal ie. regen and dpf cleaning cycle?

I don't know much about how it all works but have a rough idea and I'm thinking that if the EGR is all sooted up, will it close off properly and stop any exhaust gas being recirculated through the engine when unplugged?
If I wanted them to blank it off physically, does it need to be removed to fit the blanking plates or can they be fitted relatively easily?

I believe that it's very difficult to work on the EGR due to its location - two other garages that I've tried wont tackle it so getting someone who knows what they're doing and is actually willing to work on it is a nightmare.

I had a Toyota HiAce prior to this T6 - bought new, had it for 13 years and 160000 miles and had one repair in all that time, a replacement radiator. Everything else was just normal service items. They don't make 'em like they used to.....

Thanks fo any info

@tr7dan what’s your location…. @Dav-Tec sorted my EGR and he’s based in Chesterfield if that’s any good to you?
 
Where does the soot go when not recirculated by the EGR? Through the DPF, that's where. We all know what's in store next store, don't we?

My Son found this out on his Audi A5, so fitted a Darkside DPF delete pipe as well. Obviously doing this has MOT implications, but we all know a man...
 
The soot goes to the DPF regardless.

The EGR lowers NOx gas emissions by lowering combustion temperatures. If anything that increases the propensity for an engine to emit soot. EGR deletion does nothing to adversely affect the DPF as far as soot is concerned.
 
A related question regarding EGR removal...

What you read most is fitting blanking plates and code the EGR out to avoid the error messages. My question is, coding out the EGR doesn't change the fuel maps and AFAIK the required changes from removing the EGR are outside the compensation range of the MAP sensor alone? Doesn't the engine need a remap as well?
 
Have you had the EGR flushed by VW?
While I'll admit I'm not a fan of what sounds like a bit of farting around and hoping but I had the EGR flushed under warranty within the year when I first got the camper back in 2019 (used 2017 van conversion).
At that point it had done about 38k miles, this year it was done again with the mileage at 58k, each time they removed the EGR for the cleaning and fitted a new corrugated pipe, like you I probably haven't run the van enough, in our case basically just holidays however five years and 20k miles wasn't horrendous for the first flush.

Give us a ring bit concerned with some of the advice you where given regarding unplugging the egr. How you getting that past an eagle eyed mot tester?

Ok, will do, thanks for the reply - who do i ask for?

Wish you were a bit closer tbh but I'm near Wigan so about 70 miles away....

70 miles isn't very far to get the job done properly. Mine was done about 2 years ago by Dav-Tec, maybe longer and I've had no issues. Regens still occur at similar mileage intervals and it's been through a couple of MOT's without issue.

I agree.... and if I knew I could get the job done properly I would be there in a heartbeat.... but the van is now permanently in limp mode with the coil light flashing every time I start the engine so a bit worried about whether it would get me there in one piece.

The indy who did the diagnostics said the only advice he could give would be to not use the van until the fault is fixed, but that may be just standard rhetoric, so it's currently sitting on my drive out of action. Unfortunately they can't do the repair for 4-6 weeks and will only replace and not delete anyway.
 
I’m also curious on this. Have a 2019 T28 stage 1 remap so not sure if my EGR is already done and if it’s worth getting ad blu deleted etc.
