EGR should we all be more concerned

[gldgti]

It's pretty simple to justify the hassle, for once the price of fuel gets ludicrous, given the depression delay in oil and fuel infrastructure at present, and the massive demand spike that will happen in a year or so time when things recover, everyone will be wanting to get as many km's out of each $2.50 per litre they can. My money is on the fact petrol will go over $2 early next year, and keep climbing. In the 2-4 years most people keep newer cars, fuel is going to become a major cost component.

I figure the hassle with a Provent vs preparing for "mad max" times is worthwhile. Heck, come armageddon, you can make your own diesel from the zombies you catch.

yeah, animal fats work OK.. just not so good in the high country

Okay, thanks for that.
I had a read through the whole thread and the only solutions seem to be the VAGCOM setting and ProVent fitting.

I realise this takes a while to build up in engines (somewhere around 150k - 200k) but i would still look at fitting a ProVent system as soon as i could if i got the diesel Tig.

The main reason i was asking is that i have to justify the extra 3k in the RRP and then extra if i needed to do work on the EGR to get the TDi over the petrol.

It depends how do you drive. If you drive gently (normally) than petrol engine would still return good fuel economy. But should the fuel prices move sharply up, than even 2 liters difference in fuel economy would be a big amount over longer period of time. I prefer diesel you can still push engine hard, have a little bit of fun and fuel consumption is still good.

These were not my pictures, I found that website.
Some posters there soak it in the brake fluid for 3 days and than wash it of with degreaser. Some use kerosene and hot soapy water. Of course parts removed from engine. These were very high mileage engines with + 170,000 km.

I used to deal with similar carbon build-ups in the aircraft industry.

We had a 2000L tank of heated >brain faid< (some type of drain cleaner that came in flakes & stunk). The heat was quite high - maybe 10c below boiling. We would throw the parts in overnight and close the lid. Take it out the next day & blast it with a steam cleaner. Repeat the process until most of it was gone & give it to the bead blasters to finish it off.

So who sells the Provent, I think i'll have to have one on the MkV and plum it to the exhaust seems to be a good idea.

the answer to that is covered in another thread called "the tinkering begins"

Hi,
Yes, the amount of black greasy 'soot' in the egr system which eventually finds it's way into the turbo can cause a few problems.
Some of you might know when I return later in the year I will be offering a remapping (reflash) service.

I wondered if your cars are under warranty and the turbo fails if the dealer is accepting to replace for free.

The company that is supporting me offers an egr blanking kit and I am considering selling this kit. This problem is widely reported on my forums in UK including seatcupra.net, (golf) mkiv and others.
I wondered if many members here would be interested in purchasing a kit and I could supply either on an individual basis or offer a group buy?

I have 2 pictures of the egr blanking kit for your information:

I managed to get into EGR valve and EGR motor flap section and nearly had heart attack when I saw amount of black sht inside. The car was regularly serviced and clocked 65K in 4years. I cleaned it, but motor was damaged already so the car is back to the dealer.. it must have a catch can otherwise this will happen again. The deposits were 3-4 mm thick and some could only be removed with metal brush. I am considering fixing it and getting the magic catch can or sell the car. It took 2 hours to remove all bolts as two of them were completely inaccessible.

As far as blanking kit is concerned I thought it would only be applicable to mkIV or CR generation. mkV with Pump Duze system cannot be by-passed and this I discovered from UK forum as well. I guess ECU remapping won't solve our problem unless you have something to show here..

Ok the remap sounds good BUT, what are the changes you propose and how's it done? How much $? Where?

a guy in the polo forum [decat] with a pd130 turbo [96kw za polo tdi] has had it turned down via a tune. i'm gonna be looking to do the same once i sort some other stuff out.

What are the chemical cleaning options available to clean the intake manifold and egr when still on the car? I dont want to dismantle the intake system and turbo. Just want to spray something in and clean most of the junk out including the soot buildup on the variable vanes of the turbo.

Does the Interject stuff work? Is the Wynns stuff available here?
