EGR Delete 180bhp

I did try using the search function but couldn’t find exactly what I was looking for, so hopefully someone can help.

I own a 2016 T32 4Motion 180 BHP, currently on around 100k miles. I’m the second owner and it has a full, comprehensive service history.

The van has the uprated oil cooler, which I believe it’s had since new, but I’m wondering whether I should be considering an EGR delete.

If it’s worth doing, what’s the best option to go for? Is it a case of fitting a specific kit, or is it more software/electronic based? I seem to remember hearing about some sort of electronic device, but I’m not entirely sure.

Also, could someone explain exactly what the EGR valve does? I understand it has something to do with exhaust gases and emissions, but I’m not 100% clear on its role. If the EGR is deleted or disabled, are there any possible knock-on effects or risks to other engine components, or is it purely emissions-related?

Just trying to understand whether removing it could potentially cause problems elsewhere before making any decisions.
 
If you want to give us a call I'll go through it bud. Happy for a call any day even today if your in need matey 07823449588

Its recirculates a minor volume of exhaust gases back into the combustion chamber to re-burned. It brings a very significant reduction in NOx emissions, which are a serious risk to human respiratory health (in short it kills people, particularly children and the elderly) and is category of minor greenhouse gases.

It has a secondary effect, probably unintended when they were invented, of lowering combustion temperatures and reducing the speed of the flame front which allows more complete combustion. This is actually beneficial in a very minor for both economy and performance if its working properly.

Why? I resume your van is running well in your daily motoring as you make no mention of any problems. If thats the case theres no benefit to be gained at this point from fiddling with it. If/when it acts up is the time to be addressing any problems.

Removing it is unlikely to cause mechanical problems if its done well.
 
Can someone clarify if deleting the EGR means that the vehicle becomes non-roadworthy (illegal to use on the public highway)? I know that is the case with Adblue/DPF systems.
Cheers

Technically, yes, and now DavTec knows you're using it on the road he commits an offence as well - some things are best not intimated on a public forum. Signed disclaimers etc count for nothing in court when the customer drives to and from the workshop, and may even be construed as an attempt to pervert the course of justice.

That said, the odds of being caught at the moment are minimal so the risk to you is low. Mind you, if you are caught you're looking a £2.5k fine, a prohibition notice on the van so it cant be driven until repaired and inspected, even potential forfeiture of the vehicle if you decide to instead argue it in court, so in in that scenario it would have been less expensive to repair a vehicle properly.

Im of the view that if a person cant afford to maintain or repair a vehicle properly they should be driving something else. But thats my personal perspective. You do as your conscience dictates, I shan't preach, but those are the risks if it goes south on you. In short it is unlawful, but plenty of folk do it anyway.

There’s no reason to fit an aftermarket oil cooler to the CFCA, the OEM does a perfectly good job. The CFCA engine has a combined oil filter, oil cooler and EGR.
I suspect if your van is now at 100K miles somebody has already made some modifications to deal with the problematic CFCA EGR. The Tafmet kit is not obvious unless you know what you are looking for.

The problems with the EGR on the 180 are nothing to do with being able to afford to maintain the vehicle or any concerns about emissions positive or negative. Whether you have the first iteration or the latest, the EGR will kill your engine eventually, the only way to run a 180 long term is to blank it. It's that or a £12k bill unfortunately.
 
At that age a 180 would have been supplied with the revision D cooler, supposedly fitted from July 2015 onwards, so - theoretically at least - that aspect shouldn't be a consideration. That the vehicle has made it to 100k without symptoms suggests either this is the case, or its been fitted with the revised item fairly early in its life.

That leaves the other considerations that concern diesel owners with EGR equipped motors, and my comments apply there.

Ues that is what i meant. It had the D cooler, i have loads of historyvand stacks of recipts and it looks like it was on from new, yhe previous owner certainly didnt ever change it to his knowledge.

The D cooler doesn't resolve the issue, that's the point I'm making. It also breaks down internally and releases aluminium into the cylinders the same as the old revisions just potentially at a slower rate or it takes longer before the same happens. Ultimately, same difference it will write off the engine in the end.

To make 100k without issues would suggest the owner has been very lucky or as has been suggested previously, the EGR is already blanked off.

Hi pal sorry to bother you. I've been looking all over the place for the full kit from tafmet to compleatly bypass the cooler but im struggling, I've even sent them an email. You wouldnt know a link would you? I was going to dm you but cant

Thanks for that, i still need to reserch as i would of thought it needs a pipe bypassing the cooler no?

Get the EGR blanked off and emulated and then you can deal with the coolant, that's the most serious and imminent threat. I've had mine blanked for a number of years and just getting around to sorting the coolant pipes - it does need doing as they will apparently go through eventually.
