This happens only when engine is fully warmed up. Actually, the warmer it is outside the faster it shows the message (message doesn't appear right away...I have to feather the throttle for about 100-200 meters, then it shows the message.)

Also i've noticed, that sometimes when i'm accelerating more easily, there is a bit of twitching or how should I describe it... I'm getting really frustrated with this car :-(

it really seems an injector fault, i know that you already changed one but im 99% convinced that there is at least another one wrecked...make a bench test to all of them, or you already did it?

I'M GOING TO WRITE IN CAPITALS. EACH INJECTOR SHOULD BE CODED TO THE ECU. If it isn't, you're in for trouble.

Injectors are coded. I didn't put it in myself-my mechanic did, and I'm quite sure he had coded it.

I'm also suspecting another injectior... :-(

Will get it sorted as soon as my wallet lets me... I'll post news.

PS: Is there any chance that injectior will cause other problems...I've read there is a chance injectiors can damage other parts of the engine....something doing with letting to much diesel in the cylinders.

its a possibility but you have to live with that until the problem isnt solved... :(

Without reading the entire thread again, I would suggest going back to basics - get scanner codes, read the manuals, and think. Do this before disturbing the injector pipework - this is something Renault insist you replace if disturbed. That isn't cheap, neither is a properly coded injector - this is not DIY work - and the injector coding, I believe, is owing to its delivery rate, so unless I'm proven wrong, a backstreet garage won't have this facility.

Dave is right. I read again all posts by Pirmoz and found two issues that need to be clarified. The first is the glow plug testing procedure. It is not clear whether the battery voltage is present on then at the right time only or always. Furthermore, the plugs themselves were not tested. The second is the EGR vlave. It looks like a second-hand valve is installed, and it was not tested. The connections to the valve were not tested as well.

Apart from the above issues I find it strange that althoug this thread is going on since January, no proper OBD test was conducted. I don't see the lists of codes and plots of live parameters under the fault conditions. Just plug the OBD interface into the car, pair it to a laptop or mobile phone and drive. It makes sense to to this once a year regardless of faults - just to have reference data for comparison in case a fault occurrs in future.

Pirmoz, If you want to start enjoying your car again, please introduce more structure into your actions and this discussion.

Hey!

Yes I know...sorry for making a mess from everything... Thread is going on from january, because back then it was a different problem...I didn't want to open a new topic so I continued this one....
If anything is confusing about my english, I'm apologizing... I am not British =)

So...The plugs WERE tested and everything is alright.
The first error was on the no.1 injectior which was then changed. This led to another problem that is metnioned a few posts back. (getting the "message" which then dissapears on it's own.)
Connecting it to a computer now showed a faulty no.2 injector :-( . No other errors were found.

I'm asking you now (new question =P)...is there any point changing them one by one...it looks like the are all faulty.
Another question... If a connecting rod bearing is faulty...when does the sound appear (cold or warm?)

Again sorry for all the inconvenience...

Cheers :)

change one at the time, but, and this is very important, assure that youre using injectors with the proper I2C code. Im assuming that you swapped the injector with a reburb one, its a lot cheaper and its worth. The refurbished ones NEED, REALLY NEED, to have a new I2C code created, that code is the one with 16 digits (0 to 1 and A to F) that is attached to the injector that Dave told before that must be coded on the ECU. If the injector comes with a code that doesnt match its characteristics you may have problems like youre having now, so be sure the code is brand new for that injector.

One other thing, dont mix up injectors EJBR 3201 (delphi reference) and EJBR 1001 or whatever, they can be for the same engine code but once you use EJBR 1001 on one engine they must be all EJBR 1001, if you use EJBR 3201 they must be all EJBR 3201, i think you get the idea. If you cannot find the one you need you should (expensive) swap all the injectors.

good luck

Woow...complycated. My mechanic does all the work and basicaly I have no idea what he's doing.

Can I find this numbers without taking the injectors out?

The first injector was replaced with a new one... which he got for me...

If I am getting the point...not all the injectors ment for 1.5 60kW dCi engines are the same? I know that injectiors for 60 and 74 kW engines are different, but is there any difference of the ones for 60 kW?

Thanks for that info...I Will take a closer look.

Cheers!

I don't know, Pirmoz. One can find all part numbers and options in Dialogys system, which dealers have and which is available cheap from ebay.

All together it is strange if more than one injector fail at the same time. This may be an indication of a different problem (e.g. fuel system contamination) or a error in the diagnosis.

Thanks AlexB for ALL you help!

I've decided I'm going to visit a different mechanic...this one is suspicious.

Again thanks! And I will get back to you.

Cheers!

Makes sense. Please come back after this. Even if you stay with the same mechanic, still show the car to somebody else. We are stuck without new information.
