Fit it and see ..................:surprise:




THIS is exactly why I commented to use a broad fan spray pattern at low pressure - you used a needle pattern there https://www.renaultforums.co.uk/4211357-post23.html

 

[eoptio]

yes, I recalled your comment re the spray pattern on the pressure washer too late. I used the garden hose only for the rinsing after the engine cleaner but damage done by then. Can it do any harm in this state, I don't want to create more issues with the car...

If all the broken pieces are out of the flow path, then mechanically I doubt it will cause you drama. If you check and confirm the pressure sensor port/tube/pipes and actual sensor is clean and ok, then chances are it will still work - you will have a reduced efficiency/capacity of the cat though. Id say assemble and test - DPF part is bound to be sorted - at worst you are now at the point where the garage was initially............... iow to replce the dpf.


This experience will be very good reference for future readers - would appreciate your further feedback if you do fit and try it

So you have DECaTTED it then, just fit knowing you are never gone to have the problem again.
but dont tell MOTer,, LOL

Watch the horde of new threads appearing here now on THAT subject!:laugh:

Well he has not cut it open, no obvious markings on the outside..

Good to go..

I can see a certain Irishman asking if he can gain more power by modding his exhaust this way [emoji1]

Who are you blubing about now,

How’s baby matey?
Seen you twice out in the gold meg, looks nice with the back door painted. Beeped the horn to you yesterday morning as you were pulling up at your house. [emoji1]

Its a silver tailgate with top opening window, ( 20£ taken off for him ) Its not me you see, its the lad driving it,. I am clean shaven again, kids bought me a beard trimmer, not got used to it yet, and put a stripe down the side of my face..
I used the Astra , when mine was off the road.(had to get mine sorted, would end up with a driving ban, cars should not be allowed to be that fast , )
Mine is all up and running again, done 10 miles in it, I know, I drive too much ..
But today, it went back up to 22.4 mpg, how good is that..

Must get my glasses checked or at least take them out of the drawer. [emoji1]
Thought it was you on the newspaper run buddy.
My old man asked me two weeks ago if you’d service his shogun in March (2010 model with 7k on the clock), good job I didn’t rush though, the mad bugger showed up on Thursday in a brand new outlander phev [emoji1]
Glad baby is fixed, look on the brighter side, you’ll be able to carry more tools...

Hi all

I have put it all back together today and cleared the fault codes. Took the car for a test drive, got 'stop' message and fault code for the temp sensor within 500 mtrs, cleared that as I thought perhaps there is still some liquid in the dpf that may affect sensor readings and trigger fault codes. Drove 15 miles or so in 4th gear keeping the revs around 2500/3000, fault code did not come back and it attempted two dpf regenerations which both failed. Then did a forced dpf regeneration to see if that would work, it took approx 15 mins and the diagnostic software said completed successfuIly.

The soot level before the dpf cleaning was around 60g, after I put it back together it (oddly?) still read 60g, after the initial test drive but before the forced regen it read 18g (maybe the ecu needs some time to recalculate things). After the forced regen it stil read 18g.

Drove another 30 or so miles, according to the diagnostic sw it did not attempt further regenerations but oddly it alo does not list any successful regeneration, should it not at least list one, the forced regeneration?

The temp. sensor fault code has not come back yet, but there is a fault dtc02033a on injector 3, this has been there in the past and was put down previously by renault to a an issue with the injector connector.

So in summary, the cleaning seems to have lowered the level of soot, it seemingly did a forced regeneration successfully, but this could just be down to the dpf having been cleaned and the ecu 'thinking' it has successfully completed a regeneration. I have not yet seen a successful other regeneration. I guess I'll just have to drive it to see what happens. All sensors seem to provide data, attached a snapshot taken at engine idle. Any feedback on the sensor data welcome, ie does that look 'normal'.

thanks all

particle filter differential pressure ..................... down from 55 to 5 .................nice!:grin2:


Drive the thing and see - dont expect a regen every trip.


Sort the injector ................... its going to possibly again clog the dpf and prevent the start of auto regens and even prevent manual regens.:frown2:


Regen WILL NOT happen with most ECU errors present

got 'stop' message and fault code for the temp sensor within 500 mtrs

? .............. which temp sensor what exact code? ........... you may be right - some moisture still needed to get burned out of a hidden pocket somewhere


You need new oil!

 

[eoptio]

the temp sensor in the dpf, code 'dtc0200292, turbine downstream temperature regulation'. Yes I'll probably change the injector and i'll change the oil and filter again, just changed it after the previous forced regen...

 

[ours2012]

Would leave the oil for a few weeks ,,
Make sure everything else is ok first..
Missed something here in 12 pages, what injector?

 

[eoptio]

yes I may leave the oil until we've driven the car some more, re injector bit of a long story..after putting the dpf back on, and after the test drive, I got error code DTC02033a for cylinder 3. This error has been there in the past several times. The 'stop' light and 'engine damage risk' warning would normally (although not this time) come on, but would disappear after a few moments, normally after restarting the car. Renault has looked at this previously and said it was the connector of the injector, not the injector itself. Their suggested official repair was to change the engine wiring loom....although it was suggested it was also possible to change the connector itself, but Renault could not supply this. The advice at the time was not to worry about it, there was no problem driving the car. There is an issue with the connector on this injector in sofar that the locking mechanism of the connector has been broken somewhere in the past and the connector is held on to the injector with a cable tie instead, can't see that being an issue though.

The error came back recently at the same time as the error relating to the dpf being blocked. At that point Renault suggested that the injector needed changing. When I asked if they were sure about it being the injector and not the connector they said it could still be the connector...slowly losing faith in what I was being told by Renault I decided to not change the injector at that point. There also was no suggestion the blocked dpf and the injector fault could be related, although we did ask what could cause the dpf to block.

I don't know if the two issues are related, they may be, but as this error is coming back regularly I thought it best to change the injector, so it's known good. NB I changed the injector on cylinder 4 recently as that was broken.

 

[ours2012]

Right 0203.. 3a..

That makes more sense..
0203, = electrical fault on injector 3, 3a is the actual type of fault..

 

[eoptio]

thanks, 3a indicating what type of fault?
