Does anyone cleaned or repaired the EGS or ECG valve by him or herself? I mean the valve that gets stuck or really dirty and then your JTD has less power. I think this recycles the exhaust gasses.
I have seen some topic about it I remember?
I've been doing some DIY on old renault 4 but the Doblo engine looks a 'little bit' more high tech. I'm wondering if it's an easy fix? Thanks!

I renew the EGR not clean it.

The EGR valve on our 1.9 JTD was removed from the vehicle and cleaned by our local independant garage when it stuck open earlier this year. It has performed ok ever since - approx 70,000 miles ago.

Hope a clean works for you as well. Obviously if you're paying 'top dollar' at an expensive dealer then it may be more efficient to have a replacement fitted.

Thanks for your fast answers! If its a job any garage can do I will go to a local garage. Fiats' gonna cost me probably. Neither of you did it yourself? Maybe Ozzie? He's got a manual? :yum:

I think T14086 is a mechanic and so has to weigh up the value of parts against time taken to 'service/repair' a faulty/dirty part. Obviously new parts will come with some form of warranty.

In my case I am lucky to have found and very good independant garage that charge a very fair price for their time/skill but also take the time and effort to think about a problem before throwing new parts at a problem.

Having looked at the egr valve I suspect most well equiped home mechanics could remove and clean the egr valve.

Maus,

I did fully dismantle and repair the EGR valve on my JTD Doblo. It was stuck solid and required more than cleaning in my case. Cleaning and decoking the valve is quite easily done if that is all that is required. The trick is knowing how to dismantle the solenoid assembly and free a stuck solenoid.
If you do want to strip down the valve and solenoid than you will need to be well equipped with tools. In my case I removed the metal plug preventing access to the solenoid plunger by drilling and tapping two 5mm holes 10mm deep on either side of the plug. I ran 5mm studding into the holes lightly drilled out the peening used to retain the plug and then pulled the plug out using the 5mm studding. I then had sufficient access to get a heavy drill chuck to grip the solenoid plunger spindle and remove it after a good soaking in Plus gas. The plunger was quite pitted but it polished up OK. The EGR was reassembled and has worked without problem for 10K miles.

It would never be economic for a Garage to undertake this repair and I'm sure it won't be endorsed by Fiat. I decided I had nothing to loose! If anyone decides to have a go at this method to free a stuck EGR solenoid then you will need Hex keys (and patience) to remove the EGR valve. Torx keys to split the solenoid and other bits and pieces as detailed.

Sorry guys a bit late on this one

It's cheaper and easier to replace the EGR valve (if you don't have the time and tools to do it) but as has now been proved you can repair them if you do!

Fixing like this is too much for me I think but maybe replacing. I also need a dictionary for your 'tutorial' for all the tech English but thanks anyway.

As mentioned for garages is more efficent to renew EGR,thing is what if you remove/clean then replace it and its still faulty,you cant charge the customer for that so its better all round to renew.However be careful as air flow meter faults are very similar to EGR faults.

Saying that my FIAT dealer was tight enough to do this to mine rather than replace it. Cleaning it lasted for about 5 miles! It would have been more cost effective for them to have just replaced it as it was under warranty anyway.
