Decided to blank off my egr intake with a plate replacing the metal gasket in the pipe connecting the down pipe to the underside of the egr valve
The engine check light comes on for about 50 miles and then goes out again comes on and then goes out again, this I can live with.
Car now goes better uses less fuel and feels alot smoother
I will keep posting in the event the ecu learns that the car is running cleaner and as such the light may not come back on.
I know its easier to block the pipe with a screw, I just fancied having a proper go at stopping the bloody thing working with the light off

There's a thread somewhere on SCN where the gasket can be replaced with one with a smaller diameter hole in it. So this doesn't completely blank off the intake but reduces it to a minimum. Standard part available from Skoda dealers for around £2.
 
Has anyone used this gasket mod on here? What about the sludge issue?

Have done same mod to my Toledo 110 tdi and do not get engine light come on. Do not understand why it should come on, is there a sensor monitoring the inlet?
I used a piece of 2mm ally plate that I had around, which works well.
 
The system used on the later pd engines is pretty hi tec. I honestly thought that the light would not have come on but that was wishful thinking. It does however go off and then come come back on again.
 
the 110 uses the EDC15 ecu, the newer pd's [2004 onwards IIRC] use the EDC16 ecu which lights up the engine check light if it senses the EGR isn't working properly.

this has been discussed many times, I guess the only way to get rid of the damn light is getting the ecu mapped.
 
sweet! guess what im doing next weekend :)

just out of interest have the people whove done this also done the crankcase ventilation mod as well? i dont suppose there is any need if the egr is blanked off as both the exhaust and crankase crud cant mix in the inlet manifold any more after the blanking cap is fitted? :headhurt:
 
If you completely blank off the EGR or block the vacuum pipe with EDC16 ECUs (~2004-onwards cars) then you'll probably get an error light. In which case, the best compromise would be to fit the blanking plate that has a small hole in it (as discussed above).

If you have an earlier EDC15 ECU you should be fine, easiest method is to bung something up the vacuum pipe to block it, 2 minute job.

You can reduce the EGR function with vag-com, but that won't stop it completely.

Or you can get a remap and at the same time get the person doing the map to map out the EGR function.
 
ill try the plate with a small hole route i think, ill make when when im back at work.

could possibly try the vag-com as we have the whole software for vw/audi at work, but my computer skils are poor at best so i think ill try the mechanical route!

but im just thinking that the egr 'removal' is enough to stop the crud developing in the inlet manifold as the positive crankcase ventilation gases have no exhaust to mix with from the egr, therefore no more gunk should build up right?

On my 2004 TopSport I got this Check Engine light come on. Made some adjustments via VAG-COM entering maximal posible value in Addaption chanel 3. But still time after time got this error:
EGR system limitation limit exeeded.

So after some time I put that EGR vacum hose back. And still thinking, that driving in the city with original system gave me more miles per gallon.
 
are we talking the small vacumm hose on top of the egr?goes into the flat plate like thing on the top?
 
Yes the hose going into EGR. Disconect that hose and block it with some proper size screw.
But also what I have heard from diesel specialists, that disabling EGR causes quicker CAT clogment...

Can't understand why that should happen.
By disabling the EGR, the engine will get more fresh air (instead of being partly mixed with exhaust gas), therefore more oxygen to cleanly burn the fuel, and therefore less smoke :shrug: Although I suspect the amounts are comparitively tiny and the EGR only works under certain circumstances anyway.
