Does the egr not warm the engine up quicker too so increases MPG theoretically.

The elephant mod is a bodge in my eyes,ask anyone that rides a motorbike what they think of you dropping oil from a open breather onto the road surface!!!!

 

 

How have you found your car without the anti-shudder valve fitted?

 

Only thing that worries me about fitting a EGR delete,don't want the car to sound like a old Sherpa van when you turn the engine off!!!!

 

There is a very slight shudder, would be lying if I said there wasn't, and this coming from someone very picky about how there car performs, if something not perfect then I would NOT live with it just because its safe and MOT passable, if something out there can make my car perform or feel better than I want it and its only a matter of given time to save the cash up until I get it, I want and demand and am willing to spend thousands in time to upgrade and maintain my car to the standard I want.

 

So as for the slight shudder when u turn the engine off, coming from me who demands the standards above from my car, it does not bother me at all,. its there but its only very slight and barely noticeable, in fact I doubt I would notice it at all if I had inherited the EGR delete when buying the car and thought noting of it, only able to notice because was used to driving with the EGR value before hand so saw the difference, even with it only been a slight difference.

 

tbh had not made the car feel any different, engine seems to run about 5-10 degrees cooler, usually ran at about 90% beforehand, never seen it go over 90% since the delete not ever, 80 to 85ish seems to be the normal now, not sure if its just the weather been cooler, only brought the car end of this summer. thats about all, car has always been in excellent health tho from the day of purchase, seemed to run fine even with the EGR leaking oil, thats why I deleted. runs fine still without it no better or worse really.

 

If I drive like a granddad then I can achieve on average up to 56 MPG, normal for me before the delete was around 48 now its more like 49-50 to not a big turn on there also, in fact 48 is still not that uncommon.

Ok nice one thanks

 

Will get one at some time.

Im still guna put a egr delete in mine as the oil is leaking out of mine atm. And i think i will still do the elephant mod as well as clean eberything out. That way it should be alot cleaner :-D and the elepehant mod dosnt chuck oil out so isnt that bad for bikers its just a vapour.

You can always use one of these for the Elephant mod, thinking I may gap one of these for myself even, not a bad price and much more tidy than just running a pipe out down the bottom of the car, comes in different colours too.

I think you need a 19mm inlet as that is the size of the CCV hose, otherwise it may cause unwanted pressure but using a vented catch can is the way I'll be going.

So what is vapour then if its not a light film of oil?

 

Its a bodge,end of!

 

That's why you can buy products to the job properly,oil seperators.

I think you will do well to get 19mm hose on the cam cover breather outlet,recently fitted a oil separator to mine and the cam cover outlet is circa 21mm,I couldn't find oil resistant hose in 21mm so used 22mm

Thank you for clarifying

Yea i do like the look of them.

My BLT with Allard EGR delete and Shark stage1 remap with EGR mapped out, catch tank is no longer fitted. Now vented to atmosphere beside N/S console bush.

How are you finding this set up? I'll be getting a shark map next year and I'm not sure wether to do the egr delete or not. Ben at shark said it's not really beneficial and doesn't really make a difference in power/economy.

I have done the elephant mod so it should be ok in terms of staying clean.

If anything the EGR delete cured the flat spot at 1800 rpm

More likely cured by the good clean you gave it when you removed the gunked up sticking EGR valve from the gunked up sticky plenum.

It had only covered around 30k miles at the time so it wasn't too bad.

how about getting off your high horse and actually giving everyone some real proof of what you keep preaching then?

In my book adding 10% of exhaust gasses to the inlet stream is never ever going to benefit anyone looking to keep the engine healthy and is only done to lower NOX particulates so manufactures have less tax to pay on new car sales.

even vw admitted the egr causes a shudder on the 130pd at 1800rpm otherwise they wouldn't have made and sold a gasket wit the 9mm hole in.

ask any vauxhall dealer about egr faults and they will tell you that vauxhall themselves supply an updated firmware for the ecu that deletes the egr (certainly on the petrol engines anyway)..

yes maybe the engine runs lean when the egr is activated but it's diesel so not really such a thing as  too lean as having no throttle valve it will only produce the amount of power for the amount of fuel injected and no amount of sooty exhaust fumes recycled is going to gain power..

I think you may have misunderstood my intention and misconstrued my response. Bad day?

 

A high standard of technical education and years of experience isn't a 'high horse', years of study was hard work, being a junior engineer was hard work, being an engineer is hard work so I think I've served my time and earned the right to assert some authority, the people who pay me certainly think so anyway.

 

Look, even Shark say that deleting the EGR doesn't really achieve anything, I've always maintained that reducing emissions and increasing fuel economy are important but the EGT issue affects turbo reliability and is a really big deal, especially if the stupid mod being done DOESN'T increase power but DOES increase fuel consumption, DOES raise EGT and DOES increase emissions.

 

That's an awful lot of con's and no pro's.

 

Is that clear enough for you?

Do you have any hard evidence that you can reference that shows that the egr valve doesn't reduce power and decreases fuel economy?

I don't mean website links I mean proper journal articles etc as every single one I've read for my diss says quite the opposite of what you're suggesting!

To be fair Dave ( it is Dave is it) you are coming across as a bit of a billy know it all if you read your replys back , I've had a very good day thanks ,(my birthday) but I just thought as your replys tend to suggest you know better then it wouldn't hurt to give a proper answer. I would like to know why vw make the egr reducing gasket tho if it causes no issue?.

Just my 2p worth tho and I know nothing about anything so the more I'm told the more I learn..

EGR in any engine will of course reduce power and efficiency if it's done while the engine is under heavy load, this is why it is mapped to take place when the engine is under a light load during cruise or at idle when you don't need the power.

 

On a turbodiesel EGR allows the ECU to lean off the fuel trim without raising EGT, this leaning increases fuel economy at idle and during cruise allowing for better headline figures and lower emissions at the steady state test speeds. As soon as you put your foot down the valve shuts and you get pure air. When you delete the EGR system without correctly remapping to compensate then you are subjecting your turbo to higher EGT, and variable nozzle turbos really don't like high EGT.

 

In a petrol engine it's function is markedly different because EGR is active far more to help reduce the pumping losses associated with having a throttle plate.

 

To be honest the latest and greatest EGR systems are really giving you something for nothing and you're going to see even more of it, particularly on petrol engines.

 

I'm not a green nutter by any stretch of the imagination but diesel exhaust emissions are becoming quite a concern due to the serious long-term health implications which are only now really becoming apparent. I can tell you that major manufacturers are putting far more R&D money into clever petrol engines because they believe diesels for passenger cars are going to go the way of the two-stroke engine and the dinosaurs.

See you could have said all that a few replies ago instead of giving one line replys...

Almost all the hgv manufacturers are doing away with egr now in favour of scr. High egt is not going to make any difference if as you said it it at idle or very light throttle tho.. Btw egr is switched off after 1 min at idle on vw stuff, still not answered my question on the reduction gasket tho....

High EGT overheats the turbo causing damage, at idle a higher EGT isn't going to do that but at 70 mph on a motorway for an hour or two it can and will.

 

The reduction gasket simply reduces EGR flow as a quick fix because the EGR valve on the PD engine is simply a switch, whereas on a petrol engine the valve flow is variable and uses a PWM signal from the ECU so you can change the EGR flow in the map.

Correct so vw think it is ok to reduce reg egr flow by 70% or so...

Had first hand experience on HGV EGR and it causes nothing but problems, as does SCR. I removed my EGR and did the ccv mod to cut down on carbon build up and remove the notorious flat spot at 1800 rpm.

Interesting read! To be honest I'm not better off because I still don't have a definitive answer as to which method is best, taking it out or leaving it in. -.-
