EGR error code - simple fix?

[C64]

My engine management light came on today and I ran Vauxcheck on it.

It gave me an error code telling me that the EGR was causing the problem.

Does it need to be replaced or can it be fixed, my bro-in-law says it's an easy fix, all I need to do is remove it and clean it, is this true?

I cleared the error code and took the car for a spin around town and it hasn't returned, it's an Astra G 1.7 CDTI, engine model Z17DTL.

Well 1st get some carb cleaner, give it a good clean put it back in and try it, if the code come back again then replace it

[z786]

yes mate, cleaning it shud do the trick
dont just spray it with carb cleaner, theres a guide somewer on the net to properly clean it, if you have trouble let me knw and i'l post a link

[C64]

Thanks guys.

If it is ~~~~ed......how much would I expect to pay for a replacement from a motor factors?

[z786]

i think they are about the ?150 mark

[C64]

~~~~, only just discovered that my EGR cannot be opened and cleaned so I need to replace it. :(

It's an 53 plate Astra 1.7 CDTI , fitted with the Z17DTL engine.

Will any EGR for the Z17DTL engine work or do I need s specific unit for my model?

Part numbers I've found so far are 98060795 and 98060796, both claim to fit the Z17DTL, but how can they if they have different part numbers?

there a right pig to change aswell m8 Vauxhall EGR Valve,98060795,Astra G,Corsa C,Meriva,1.7 | eBay UK (http://cgi.ebay.co.uk/Vauxhall-EGR-Valve-98060795-Astra-G-Corsa-C-Meriva-1-7-/190500648083) the last one l did was full off crap and the exhaust tube was well blocked too , it might only be that ?

[C64]

What about part 98060796, that fits a Z17DTL too.

I've found one considerably cheaper than the 98060795

[smirnoff_rules]

not to sure if u can swap ? just used the one for the car didnt look into it m8

[smirnoff_rules]

they are different if u look at both pictures tho Vauxhall Astra H 2005 + EGR Valve 98060796 / 97358613 | eBay UK (http://cgi.ebay.co.uk/Vauxhall-Astra-H-2005-EGR-Valve-98060796-97358613-/230501506163?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item35aaf5dc73)

[C64]

The only difference I can see is that the electric socket is pointing in a different direction.

What do I need to strip out to access it Paul?

[smirnoff_rules]

if it was my car l would clean it out there lots of channels in that hosing that can block up easy , its just not a fast fix like the older egr valves . the one l changed was blocked up but its wasnt my car and the customer money so l just changed it because it comes back on me if l clean it and charge 2 hours and its back in a week

I've just had a look under the bonnet, I can't fit the 96 model even if I wanted to as the area where the electronics connect on the 96 model is taken up by another electrical connector for something else. :(

I'll have a look at your tutorial and try a clean before I splash the cash.

cheers mate.

[C64]

I should maybe mention that this error appeared 1 week after I had change my oil, oil filter and air filter.

Could it be related in any way - particularly to the air filter?

[smirnoff_rules]

no m8 wouldnt of made a difference

[C64]

Cheers mate.

I've got a 'bloke' coming to have a look at it today, he said he'll give it a scrub with carb cleaner fluid. If that fails then I just need to find a cheap replacement and he'll fit it for me. :)

Is it worth trying a local breakers yard, or should I really just replace it with a new unit?

[grinovsky]

why you don't upload the dump from your ecu?
may be it can be desabled
and for sure it can be programmed to keep it closed

Yes but if I remove the functions of the EGR, won't I fail my next MOT?

How would I dump my ECU anyway? I only have a basic OBD II unit and Vauxcheck.

[grinovsky]

if you remove the functions of the EGR your engine wil breathe freach air

Don't go there m8 it's another world lol just get it cleaned these lads think your a mechanic m8

Yes but doesn't the EGR help burn off extra Nitrous Oxide in the exhaust gas by recycling it back to the combustion chamber?

I'm not a mechanic mate, so excuse me if I'm talking rubbish. :)

@ smirnoff..

So is the EGR essential or not mate?

I've got a mate with a Tech 2 clone, so dumping the ECU would be no problem, plus I can get a EGR blanking plate for 50p, much cheaper than the ?230 most places are wanting. :)

Paul, you seem convinced that it can be cleaned. Is it simply a matter of sticking a toothbrush into every orifice I can find and squirting in some turps or Carb cleaner?

What about the throttle body, should that be cleaned at the same time?

The last one l did was coked up very bad m8 so lm sure that a clean would of done the trick

Yes but what is involved in the cleaning?

Remember. I have a 53 plate 1.7 CDTI with a Z17DTL engine. Everywhere I've looked on the Net tells me that the EGR on this model can not be dismantled.

It can still be partially cleaned inside but many parts are simply unreachable.

I've read lots of posts on other forums from people claiming that they tried to clean this exact EGR unit and failed, simply because they cannot get full access.

I just want to verify that we are both talking about the same EGR unit.

:)

[grinovsky]

EGR does not fouled with exhaust
when an engine was watching the exhaust contains much more, there are oils, as unburned fuel and chemical reaction of any such product gives birth to a black tab that locks the egr and mouth while the induction of air engine, while the engine is choking for what it is best to disable the egr

[C64]

Won't my fuel consumption increase mate?

Also, what tool do i need to dump my ECU?

I have a OBD II unit, will this do it or will i need something like a Tech 2?

[briandsl]

hi m8 it may be worth reading link to get the facts on egr
it is fitted for a pupose but at the moment i don't uk or eurozone are testing for nox gases .hth

http://en.wikipedia.org/wiki/Exhaust_gas_recirculation

regards

[grinovsky]

your fuel consumption will decrease(you can notice your consumption before and after flashed the mode file)
you can flash your ecu with the original (backup) if you are not satisfed
i think your ecu is ecd15 ,mpps,galetto(maybe) can do it

Witchy (http://www.digital-kaos.co.uk/forums/members/196-witchy/), I may be wrong but it looks like the solenoid in your pictures could just be unscrewed & turned so your wiring will then fit (try it on your old one), also I was told by midland turbo that a malfunctioning (or disabled by software) egr valve will increase exhaust gas temperatures resulting in more heat being transferred to the turbo which in turn can cause the lubricating oil in the turbo to boil and therefore cause turbo failure, they advise checking egr valves when turbos have failed. I have no experience of disabling them so cannot say if it will cause turbo failure or not

So if it can be disconnected doesn't that mean I'll have access to the workings so I should be able to clean it out afterall?

No harm in trying, I have also had the solenoids sieze up so may not just be sooted up, but costs nothing to try
