The ultimate EGR delete yes or no?!

Personally I fitted an EGR delete and took it off after a few months because I felt it was pointless!

So I want to find out everyone's opinion on having an EGR Delete as there are a LOT of posts about it! I think it will be about fifty fifty!

Vote YES if you think an EGR Delete is worth it, or NO if it isnt!

Yes!!!

Out of interest why did you remove it mate? As in what made it pointless.

I don't think it does much in the way of performance. I think people do it more to prevent the build up of gunk from the exhaust particles mixing with the oil vapours from the crank case breather.

 

For that alone it could be worth doing to help keep things clean, performance wise not so much.

I removed it because the lack of ASV that goes with removing the EGR on the ASZ engine. Felt it could be lessening the life on the engine mounts. Also the fact I'd have to spend more cash mapping it out. There is also a lot of stuff on this forum about the good points on having one.

No. No worth it.

ECU requires updating to remove cel

Loss of ASV

Reduced mpg

Potential MOT failure in the future

Anecdotal evidence suggests that engine is slower to warm up

The elephant mod is more beneficial.

SWMBO has a BMW 320d mSport, at 75k I took the egr valve off to clean it; very badly clogged up with oily gunge. It took about 2 hours of soaking in egr cleaner and judicious scrubbing with old tooth brushes to get it clean.

If that answers the question, in an oblique manner, then yes, I'd remove it....

No, leave the EGR alone.  Do the elephant mod to stop oily crap getting into the intake and that stops the build up of gunge.

1.9TDi PD 100, 133K miles, no EGR problems. I cleaned it at ~ 110K. Car makes more than stock, no engine mods. No turbo problems either. Just regular mantenence and the correct oil.

Higher combustion temperatures will ultimately lead to reduction in component life. This is the laws of thermodynamics; this is fact.

Do VW higher idiots, no. The EGR Valve is there for a reason, it reduces combustion temp and as a result prevents NOx emissions by recirculating air and fuel. I was on the fence with an egr delete but who am I to essentially claim I know more about the combustion engine than world wide manufacturers.

I vote NO

No, the elephant mod and correct care and maintenance will suffice.

Yes delete the hell out of it!! You know it makes sense

if VW werent bound by the EU emissions laws would they have fit an EGR system?.... No

I'm inclined to disagree as environmental marketing makes their companies look great and who wouldn't want to help preserve this planet

Even if they didn't fit this I'm sure a similar device would be implemented to ensure combustion temperatures don't exceed the threshold to ensure maximum component life and hence the great reliability we have all grown to love?

The PD lump is the reliable bit.. the EGR/ EGR Cooler (later models) DPF (again later models) + all the added on emissions stuff is where the reliability issues are.. the pre PD diesels from VW were alot more reliable + also better on fuel than the PDs.. the only downside was they were less refined.. noisier + produced more smoke..

Without the EGR you have better non restrictive air flow on the inlet side + without the CAT you have better less restrictive flow on the exhaust side.. better without both in terms of performance + MPG.

both the EGR + CAT were added for emmisions only. They dont prolong the life of the engine + the EGR just pumps crap back throught the inlet which is worse than no crap going in. The theory for the EGR is good theory.. but the reality of the gunk/ carbon it brings with the hot air is where the problem lies..

i wouldnt think of doing the "elephant mod" either without a catch can. Any risk of oily residue ending up on the road isnt worth the hazard to all the 2 wheeled comuters out there. And thats where all the oil that would normally be in the IC pipework will end up.

If the only issue was the carbon gunk, I'd maybe say leave it and just do the Elephant mod to help prevent build up.. But since it fundamentally ruins the driving experience of a BLT vRS I had it mapped out..

I've had mine mapped out but it's all still in place I've not touched it. Was it worth it? It was free with the remap so can't see it doing any harm. Would I of paid to do it specifically? Nah

I changed/deleted mine after the EGR started leaking oil and it was recommended to me by a Skoda tech, who also did the work for me.

 Mapped my own out using VAG EDC15P software. It is just a case of flattening the map, meaning that the hardware stays in place. Certainly pulls harder from cold at low revs, it always felt like a petrol car with choke on the first climb of the day.

Just do elephant mod
