Location of the EGR valve

[fbarcode]

Does anyone have a picture of EGR valve on 1.9JTD engine? I did look at the "Clean EGR valve" guide, but I can't recognize the part on the engine.

I am trying to diagnose if it is working properly, so some info about how to temporary disable it would be nice. I know that someone did say put ball bearing into the 'whatever' but I don't now where and what that 'whatever' is. A pic would be great.

Thank you in advance

This is what it looks like,

as for where it is i wouldnt know dont have a Diesel. but it is somewhere linked to the exhaust close to the engine.

There are two types which JTD engine do you have? The 105 or 100?

The above picture shown is for the 100 and is located near the rear of the engine.

The other EGR valve on the 105 is found under the plastic cover, right at the front of the engine.

I advise you not to disable it. See google for answers why not.

According to fiateper, it is a 110 version,
manufactured february 2001.

I do not want't to disable it permanently, i've read about everything I could find regarding EGR valves, just want to determine if it is functioning properly, as I am expiriencing problems in low rews, and when cruising at constant speeds.
Black smoke from exhaust and loss of power. When I put it in lower gear and then back up, problems disappear. So, based on those symptoms, it should be EGR.
I already cleaned the MAF, so it isn't causing problems.

I cleaned my MAF, nothing. Fitted a NEW one and wow what a difference. Ok the 110, so you must have a Marea yes? Only the Marea came with a 110 engine and a 130. Bravo/a came with 100 and 105.

If its the EGR you will either experience a bad knocking sound, rough idle, hesitation and possible stalling.

If your problem is your car wont go beyond 3500rpms or struggles to go pass this then its the MAF sensor.

Thank you for your reply.

It is marea, sorry, I didn't mention it, weekend actually.

When I cruise for a while at 2000RPM in 5th gear, I notice black smoke from the exhaust at irregular intervals (like: smoke, nothing, smoke,nothing,nothing,smoke, you get the idea). And I can push the pedal to the floor, and nothing happens, just more black smoke. Then i put it back to 4th, go to 3000-3500, back in the 5th and problem is solved (for a while).
Also, on a very cold morning, in 1st gear, it just does not want to accelerate, and lots of black smoke. Then I push it to 3500 in 1st gear and problem is gone. Really weird.

I tought that it would be EGR related, since it sort of 'cleans' itself in high revs, but maybe I'm wrong. Garage supposedly cleaned the EGR, but symptoms remain.

I don't drive my engine beyond 3500 often, so I can't say if it is struggling to go past 3500.

And another thing. Before I cleaned the MAF, the symptoms were noticable all the time (lousy acceleration, and when I cleaned MAF, in a day or two it began to jump a bit (lousy and then great acceleration), and now it accelerates fine (until problem with smoke occurs).

Try taking your car above 3500rpms, see if you can redline the car. If it wont pass further than 3500rpms or wont redline full stop, then its the MAF.

EGR and MAF are related but it sounds like an air restriction. MAF is for the air flow. EGR just recirculates the exhaust gases.

I mean you could replace both with new parts. Will probably solve the problem but will probably cost you around £250 in parts. Not cheap items i know.

Some people have had joy cleaning them and i personally have not.

Thanks Joske

Its the EGR valve that is open all the time - not full but 1% is inough to cause the smoke. It lets the turbo presure in the exhaust and the car dont run well.

I did a EGR cleaning and it worked some time - after ca. 4000 km it started smoking again so I blocked it off total.

All is ok, no problems and it wont afect your engine, its only for reducing exhaust fumes to the EURO norm.

But then I have a vacuume tipe.

Thank you

It can go over 3500, without any hesitation, just smokes a lot. So it could be EGR after all.

Can't I just disconnect some hose to disable it temporarily?

 

[Sven]

If its open its open - cleaning can get it working again, but it can/cant be permanent. If its a vacuume one, you can disconnect the pipe to it, but if its electric dunno

Dont forget the EGR if it is the problem will also cause the car to idle roughly and perhaps stall the car. You only seem to have the black smoke symptom. Not sure but a Fiat Diagnostic may tell you the exact problem, but then again it may not. If you feel comfident its the EGR then get it cleaned or replaced. It could be your injectors, air filter requires changing etc.

Take a picture of your engine and we can tell you where your EGR is.

No errors showed on diagnostics, no injector light, nothing.

I am at work now, so can't take the engine cover off, but could this be the EGR valve? It is between the engine and diesel filter. It has two pipes connected to it.

This photo is taken from the windshield direction.

Thanks.

Yeah thats it. I dont think that type can be cleaned i know sven shows a guide how to clean the other type of EGR valve.

But yeah thats it. If you can remove and fit another yourself it would save on labour costs.

You could try cleaning it or buy a new one from either...

Thanks.

Garage claims that they have cleaned it...And the mechanic said something like :
"Well, we cleaned it, but... try for yourself.."

I tried it, and it was OK, but as I already said, it doesn't cause problems all the time...

So can I disable it by blocking one of the pipes? Just to try if it helps?
One of the pipes(the one which could be seen on the above picture), surounded by 'shiny metal thingy' goes into a wide rubber hose.
The other one goes down to something I can't see with engine cover on.

Maybe it's stuck open a bit, so I don't have problems when running idle.

I do not wan't to spend 200 EUR on a hunch, and that's why I am boring you to death with my problem

 

[Sven]

Only way of blocking would be to insert a metal plate on the incoming exhaust pipe to it.

And it can be cleaned, just needs to be taken apart

I dont advise blocking the EGR valve at all as it will result in problems. Not to begin with but will cause more problems later on than you started with, which in end will cost you more. But so will a faulty EGR especially to the cars Turbo if the exhaust gases are high.

Hence i cant help you really. I think the EGR valve we have on our cars are part electrically operated. But the EGR must have a Vacuum pipe on it to lift the diaphram or whatever is in there to open and close the valve. I assume you block the vacuum pipe and the valve will stay as it is, which pipe it is i dont know. Again i dont recommend it.

Joske

 

[fbarcode]

Yes, I could block vacuum pipe (if I knew which one it is ) but if valve is just stuck open a bit, it won't do any good, since it will still be open even when nothing is 'trying to open it'

And regarding MAF, I remember, on a cold day, when it began to smoke like crazy upon strarting (it was before I cleaned the MAF), I disconnected the MAF, and nothing changed....

 

[Sven]

Joske, nothing will hapen if you block the EGR. It only sends the exhaust gases to be recirculated so they can coply with the EURO norm.

Blocking it will raise the exhaust emissions and no more then that. The ECU will give a EGR fault code (like mine does) and nothing more - Fiat advised me to block it, or replace it.

Guess what I did considdering it coasts 300 euro here

Sven what do you use to pull all this info from with these pictures and guides?
