EGR should we all be more concerned

[greymad]

Quite an impressive collection of the automobiles you have there.
It must be the recall for the EGR in your T5.

Yes - as I stated, it's for the EGR, but do you have any idea what the recall's about ... ie why it is necessary?

Well, here I am answering(?) my own post.
The best I could get out of the collar & tie on the front desk is that the EGR valve spindle (or whatever its real title is) tends to stick.
Not good.
I asked - "will the replacement unit do the same?"

...Of course not, sir.

Yeah, right.

Of course it will, when it gets older (used). Cleaning the t/b as a part of your 30,000km service should prevent that. Do nothing and you will have one expensive part to replace down the track.

Well what is confusing here for me is that this work (whatever it really was) was carried out within 2000km's of the vehicle's first (15,000k) service.
If the "cleaning" is a regular requirement then it should have been done at 15k.
And how long does cleaning an EGR take anyway ... they had the car for a day and a half. At least I got a loan car (even if it was a crappy well-used Caddy).

Update. Clouds of black smoke under hard takeoffs again. Only about about 20000ks since all was cleaned. Has had a restrictor in EGR cooler intake flange with a 10mm hole in it. Took it out yesterday and put in one with a 5.5mm hole. No fault code came up, so probably should have experimented a bit last time. I guess I will still have to make some some time to clean things up again and check the EGR valve is not leaking or jamming. Bloody thing.

Yesterday when driving on the freeway ENGINE EMISSIONS code came up, for first time. Then went away. Should I worry about it or continue to ignore it?

That would be due to the car registering too little EGR I reckon, 7mm seems to be the minimum hole size of choice.

Its just an annoying light, nothing to do with fuelling etc, I drove with that on and off for years.

Can some help with the location of the EGR in my 6r polo TDI and can a blank it off?

Sure, but you will then be stuck with errors and a permanent dash error light. EGR cannot be blanked totally off on most current cars, even via a tune, only reduced. Most current cars must see at least some EGR, and a final kicker is blanking it off messes up your DPF regen cycle.

[Johnnojack]

Since blanking off a greater proportion of EGR the engine seems to be idling faster, (1000rpm) I think it used to be about 900rpm. (1.9TDI)
Are the two related?
