Has Anyone Disabled Egr?

[qettyz]

Hi,

I tried to google this around and didn't find any information about this.

I have located egr pipe from my aygo, but has anydone done that?

What i need to know, that is ECU with on this, or can this pipe just be disabled without any errors by ECU?

Car is model 2010 Aygo 1.0

Don't know on an Aygo but here's my 2p worth.

My father has a Hyundai Tucson Diesel.

He drives it slowly & carefully, then tows a caravan down the motorway a couple of times a year.

This baked the Diesel soot deposits hard & jammed the EGR valve.

It shows up on the dashboard as an engine fault.

After some research......

The EGR must remain connected or an engine fault will show.

It can be prevented from sooting up by......

Remove the EGR, cut out a very thin piece of metal to fill the port hole.

eg, a beer can.

Refit the EGR.

It will then open & close and the engine management is happy,

but there will be no exhaust soot / gasses passing through it.

The engine will warm up quicker & be less dirty inside.

Perhaps you could investigate if it will have similar benefits for the petrol engine?

Hi and thanks for you post!

I have once before blocked EGR off, car was Skoda Fabia 1.9SDI (year 2001) and i blocked egr just because i didnt want to spoil my intage and so on, so no problems were from EGR. And with that car it just worked fine when fitted "blind" metalplate between EGR. So no ECU problems there.

(some cars ECu will sniff intake air via MAF and know if there is not coming any air(dirt) from EGR).

But there was a big downside, at the winter (up here at Finland) car didn't warm up, took forever to get it to blow warm air :(

But, i want some experience with Aygo anyone?

Do Aygos HAVE EGRs??

AFAIK the sole purpose of an EGR is to reduce NOX emissions (At the expense of worse MPG, increased particulates, engine wear etc.) and that isn't generally a problem in petrol cars...

It'd really suck if petrol cars have to have these money-wasting pieces of crap fitted to their cars too :(

EGR valves where first fitted to petrol engines many moons ago. I distinctly remember a 1995 Corrola having one.

Many, many petrol engines have them but they just don't cause the same problems as diesels.

Guh! These things are a disease I tell you!

The benefit on a diesel is limited to cutting down NOX emissions... what the heck do they do on petrols given that petrols don't have high NOX emissions?!

Hmm, I wonder if you could co-opt all that extra pipework to power a turbo charger...

em i dont think the tiny 1.0lrt aygo has an egr and blocking one off on a petrol car has no real advantages

I know this is an old thread but I have a 2012 1L Aygo, I was just looking at the schematic for the engine and noticed an EGR valve on the engine... I inspected the engine because I didn't think the car had an EGR valve... I found a flat surface in the shape of the 1KRs EGR valve in the position the schematic states but none of the holes have been drilled out to fit one. So I'm guessing some cars that use the same engine have the surface machined out to fit an EGR.

No EGR on the Mk1 Aygo with the 1KR

Mk2 Aygo 2014-2021, Yaris with the 1KR from 11/2008 and IQ with the 1KR* all have an EGR

 

* 1KR in the IQ uses a different engine block as the drive shafts are at the front, starter motor location and a big difference in the transmission
