Egr kits?

[RTP]

Can someone explain what the pros/cons of fitting an egr kit?

Is it a mod worth doing? I have a mapped pd100 tdi polo sport..

Hi mate,

I am led to believe from reading up on them that you are likely to get an improovement in ecconomy and throttle response. Most kits also come with a take off for a boost gauge which makes installing one a bit easier.

The downsides that i am aware of are engine shudder when you switch the engine off (this doesnt damage the engine mind) and the engine warning light being thrown up in most cases.

I will be getting an egr delete kit for my remaped gt soon though as I recently cleaned out the egr valve and intake manifold on my audi and it took me three hours to scrape all the crap out caused by the exhaust gases.

Hope this helps

Thanks for the info mate

I looked into it and thought while I was messing about with the car today I would clean the EGR and inlet pipe out..
There's a few videos on YouTube that I followed.. Wasn't to bad really.
Anyway the polos done 98k so thought it would be worth cleaning. When I got it off.. Yes the valve was clogged up, about 3-4mm of carbon all round.. So I scraped it out the valve and de-greased it.. Then I scraped the inlet pipe out with a spoon! did the job and then put it back together..

Seems to pull abit harder now, guessing because of less restriction.. Well worth doing

Here's a pic after I cleaned out the EGR valve

Hello and welcome to the forum!

Another thing worth doing for engine cleanliness/reliability is to do the Elephant Mod, which basically consists of a metre of 19mm ID silicone tube and a 25mm rubber cap (I bought a rubber end cap for the bottom of a walking stick!) Which basically stops oil vapour from the crankcase from being recirculated into the intake, which was put in place by the manufacturers for some emissions law.

A borrowed image from google:


This stops oil from building up in the intercooler pipes, keep heat transfer efficiency up in the intercooler, and stops the recirculated oil combining with the soot from the EGR to form the crap that you're all too familiar with cleaning out You'll still get some soot, but in most cases it will burn itself off.

I haven't removed the EGR as it increases engine warm-up times.

Not heard of that elephant mod before, i'll look into doing that on mine.

Couple of questions, do you need a meter of that pipe? It only looks like a a few inches on the pic.

Instead of a bung can you use a mini K&N style crankcase breather?

From the pic it seems different from mine..? Is there a link to the mod more in depth?

Cheers! Liam

The engine is slightly different but the principle is the same. There are guides on Briskoda, they're much more into the pd diesel engines as their VRSs have the same ones.

Here's the link to the guide, as you can see there are tons of people who have fitted it in different ways, loads of ideas.

In response to Benmeister, the few inches of hose you see in the pic is the bunged end, that's the intake pipe and you don't want a hole in there, it needs to be sealed. I just took off the existing 90degree pipe you'll see on a stock install and stuck a 25mm walking stick rubber over the end which sealed beautifully, some people even use corks, plastic bottlecaps, and those orange flask bungs you stole from science class at school! Pikey modding at its best.

The pipe below is a metre of silicone pipe attached to the CCV (top of the engine block) and the pipe runs down the side of the engine to the back behind the bulkhead and under the car, all that comes out of here is steam and a small amount of oil vapour. It gathers up to a lot though, I had a catch can fitted until recently and it gathered something like 50ml of water every 400 miles and a lump of oily emulsion, better off out than being redirected into the intake!

Awesome stuff I get how it all works now.

Cheers for that buddy i'll be doing this mod in the near future.
