this got an ad blue system on it, has this been checked

 

No, don't think so. They are talking about checking ERG and ECU now. Another scan being done this morning.

 

Should be able to see Soot Content In DPF and see if it has accumulated that much soot in 600 miles to trigger a fault .

 

Update this morning after another scan.
Scan has shown a particle filter fault (for the first time) with soot readings at 28.9g. My mechanic is now suggesting removal of DPF for a professional clean with print out after. That way we see if it is knackered or not.

 

Scan has shown a particle filter fault (for the first time)

?

What is that?

soot readings at 28.9g. My mechanic is now suggesting removal of DPF for a professional clean

Sorry but 29g in the DPF is nothing ...................... cannot see how a mechanic can possibly try to motivate a removal and cleaning action................ especially since you say its already been done.

He needs to start doing his job - he needs a scanner that can speak real-time live data on a Renault and inspect the DPF related parameters and progression of DPF content management during a trip.

 

these were the latest scan results

 

As a mere user of vehicles and not a mechanic I find it very difficult to distinguish between mechanics who know what they are talking about and those that don't. Seems like everyone is trawling through you tube desperately trying to find a fix as it is all computer driven these days. Every single time we have had a sensor changed or clean done different fault codes come up after a 100 miles ish. So fault codes cleared, forced regen, noc sensor replaced, dpf clean at side of road, soot sensor replaced and still the lights come on. FFS

 

I would start here:

If the engine is or has been running at the time of the scan, then you would expect temperatures in the order of 100s of C upstream of the DPF .....................

As long as this temperature is reported so low (for whatever reason) the auto regen of the DPF will NEVER either start or complete and will cause your miseries

 

Thanks, will investigate futher

 

I would say the best you can do now is to help yourself rather than rely on a bunch of yahoos taking your money for chasing codes only.

If you have access to a scanner, go drive the thing till nice and toasty, get somebody to capture ALL the ECU parameter values while you are doing constant around 50mph on a flat road.


When (time and distance covered since) was your last proper oil change ?

DPF regen will not happen with rubbish oil (safety issue) ............................ and if you have been struggling with DPF complaints for a while it may also be as simple as just changing the oil in addition to checking on that exhaust temperature

 

It needs properly scanned with Renault Clip Diagnostics as most generic scanners dont display codes properly or dont read them all.

 

Also get Renault to check your van details on there system as i think its due a software update for the inj system which is a live service bulletin at the moment.

 

Thank you for this. This sounds correct for software update BUT current wait for an appointment with my local Renault commercial is around 3 MONTHS !!! And their service is atrocious. Last time i went to main dealer (Portsmouth) we booked it in for the day having driven 50 miles. At 3.30 they said they couldn't guarantee it would be done that day. 50 miles from home with no way of getting home !! I had no choice but to take it home without them doing their diagnostic scan which is all it was in for.

 

Renault Car dealers can do updates to as the clip diagnostic is the same for all renault, but not under warranty if its a truck bought van.

 

Irrespective of the possible offer by Renault of an improved ( ) software update, the basic design/operation of the DPF stays the same and I will bet the prerequisite of edequate safe CAT/DPF temperature and oil quality cannot be addressed via a software update ...................

IMO - it's fix what is already known to be an/the identified issue and then start grasping at straws by trying to chase codes only.

Snap-on makes quality scanners in my experience .................. CLIP is not necessarily going to do any better at all .................. its the scan-tool operator that is IMO screwing the pooch here.

 

There is known technical solutions and bulletins on the Renault systems depending on what codes are logged or messages/warning lights on dash. As you can see ,the snap on scanner is showing a fault code which it says refer to manufacturer, ie it is always best to use genuine diagnostic equipment.

 

UPDATE.
Having found a mechanic who seems knowledgeable on all things DPF he recommended an off vehicle clean. We have done this and it needed to be soaked overnight twice due to build up.
The problem was AD BLUE build up ! As this vehicle was driven very short distances for it's first 3 years it seems this is where the build up started.
All seems OK now, lights are off and performance improved. 🤞

 

Ich habe dieses Problem ebenfalls, dürfte ich fragen was genau sie meinen, mit einer Reinigung außerhalb des Fahrzeugs? Ich habe bereits den Partikelfilter gewechselt und das Problem bleibt bestehen.

 

So great

Question for reference .............. what is the upstream of DPF temp now?
