Re: Particulate filter error resulting in MIL light


Read the error code when you get your scanner. Log it and then reset it if your scanner allows it. More likely the EGR - how dirty was it ?

posticon Re: Particulate filter error resulting in MIL light


Interesting thread. My 2009 T-31 has just over 50,000 km (bought second hand). The DPF light came on a month ago and I went on a drive and it cleared.

Then late last week the DPF light came on again. I guess I didn't get a chance to clear it and then the MIL light came on.

Had the car serviced at my mechanic yesterday he cleared the DPF but couldn't clear the MIL. Of course I have just had the oil and filter replaced.

Now booked in to Nissan tomorrow.

As I said interesting reading this thread - thanks!

Re:


Glenn,

Well done on your wise purchase of a diesel Exy. The diesel engine is the pick of the bunch and as you've already discovered, is GREAT on fuel and has plenty of get up and go when you need it.

Simple answer to your light issue: Whenever the it comes on, go to a NISSAN dealer. If there are ever any signs of the engine running roughly or "not right," switch it off and get a tow to the closest dealer.

There are lots of mechanics out there with PDA'a (who don't properly understand the M9R) who can clear fault codes and reset the light for you, which is a VERY BAD idea, as there are a number of faults which can trigger a several codes, which trigger the light. Without properly investigating the code, resetting the light only could see your engine become a grenade.

Unlike a tractor/truck diesel engine, the M9R regularly needs few revs and highway speeds to keep it running smoothly.

It's a fantastic little motor, which will give excellent service if understood and treated properly. The vast majority of problems arise from driving it like a 1980's truck engine, crap fuel liked you get from Woolworths Petrol, or poor maintenance.

ALWAYS GET YOUR SERVICES DONE ON TIME!

I've driven AugustusXTrail which has close to 120,000km on the clock and it still runs like the proverbial "Swiss Watch." Darren has maintained it well and most importantly has not driven it like a tractor.

If you do mainly stop start, city driving, or don't not give it any revs, then you should change your oil & filter on the 5,000 km in between services. Many of us get mid service oil changes anyway, because fresh oil can't hurt a motor.

Hopefully the code is simply a dirty EGR.

Thanks Charlie250!

Nissan performed a regen today and all seems OK. Apparently the fuel around this part of the world is not the best so will try to buy reputable fuel in future also.

No more tractor driving for me. Also love the advise re the between service oil and filter change.

Thanks and regards

Glenn

Re: Particulate filter error resulting in MIL light


Great to hear the positive outcome with the regen.

Make that diesel siiiiiiinnnnngggg! She loves a good rev every so often, and if it's a manual TS/TL, stay out of 6th gear until you reach at least 110. This helps keep the exhaust gas temp up and you'll get a better DPF regen when it occurs.

My automatic TL hardly ever makes 6th gear - it doesn't change to 6th until about 112-114 on the dial, and even then the engine needs to be at low load to kick up to 6th. So she spends most of her life running around in 5th and I still get 7.2l/100km. And I've never had a DPF light.

The M9R is a great donk...but like all things French, she's fussy and unforgiving if not treated right!

Re: Particulate filter error resulting in MIL light


Hi

I have a 2008-model T31 with 145.000km on the meter.
I've had the ordinary DFP-light coming on every once in a while, but have taken care of it with the "go for a long ride"-procedure. A few years back the Nissan-dealer carried out a forced regeneration after a "stuck" DPF-light, but that was well inside the warranty.

Well, last week I experienced the DPF-light coming on and shortly after the MEF-light as well.
I did try to take a long ride to burn of the DPF, but with no luck. Later on I've realized that the regeneration will not take place as long as the MEF-light is illuminated.

One strategy I've tried is to get rid of the MEF and then go for a long ride to regenerate, but the methods I've tried to reset MEF haven't worked (3s+pump accelerator 5x-7s-10s, and removal of the 20A-fuse in the "secret" fusebox).
Reading that stuck EGR-valve could be the cause, I did a cleaning of it like described in the DIY-guide. The valve was quite dirty, but not as bad as in the pics posted on this forum. Anyway, both the DPF and MEF lights are still on.

Next strategy I thought going to the dealer and have them try the forced regeneration.
The only issue I have with his is that they want AUD680-950 for this operation (1 or 2 times) and the oil-change and filter on top of that. Considering this process i more or less just to start a program on the computer and leave it for 40 mins I find this "a bit" pricey. And of course they can't guarantee this will work, and then we're probably end up with a new DPF. Haven't asked for a quote on this, but it will probably be in the AUD4500-6000-area.

My thoughts is then;
a) Am I on the wrong track here with my thoughts on what could be wrong? Could defect sensors on one/both sides of the DPF be the cause? The car runs very well, and I can't sense any difference in the engines behavour.
b) Should I consider buying a china-copy-consult-unit to read codes and is it possible to do forced regeneration with these units. According to the service-manual this procedure doesn't seem to complicated. .
c) Is there something else I should try.

Best regards
Espen
