T180 Embarassing Regenerations - Anyway Of Reducing Or Stopping Them

[Steve Hebby]

Is there anyway you can reduce or stop them. It is now getting very embarrassing. While on my way to work today where due to roadworks on the motorway I'm driving at 50Mph for about 20 miles at 2000ish RPM (on cruise control), the car did 3 regenerations that ran for about 10 seconds each time which seemed like an eternity when traffic around me are flashing their lights or blowing their horns.

I have seen a fuel additive on that auction site which apparently creates a catalyst that wraps around the soot deposits to reduce the need for a regeneration to burn off the soot deposits. Has anyone tried this?

Is it possible to block off the 5th injector without causing problems elsewhere?

Is it using oil?

Have you given it a good caning recently?

Have you tried a tin of BG244?

Hi Anchorman hope your keeping ok! I knew you would come to the rescue mate as you have helped me a couple of times in the past.

I'm always caning it pal i've got the Lindop chip fitted too the cars a beast.

It's not using any oil. I check the oil weekly as I average approx. 500 miles a week mainly motorway miles.

What's BG244? Is this a DPF cleaner as I've also seen on that auction site, Would that improve things.

Hello Steve,

I have used this: http://www.ebay.co.uk/sch/i.html?_nkw=Forte+DPF+cleaner&_sacat=0&_odkw=Forte&_osacat=0&_from=R40

Good additive.

After this: http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_738851_langId_-1_categoryId_255221

It also help a lot.

The BG244 is a good additive.

EGR valve you yourself can easily clean up.

How do you know when to run the regeneration?

What are the symptomps?

[Jozsef]

One more thing.

Use premium diesel fuel (Shell V-Power diesel or BP Ultimate diesel).

Will not be disappointed!

Hi Jozsef,

Thanks for the help. I clean the EGR valve regularly.

I will give the BG244 a go.

The regeneration can not be just run it runs automatically every now and then (I think it's when you get a build up of soot in the Deisel Particulate Filter (if not someone will correct me)). The symtoms are clouds of smoke coming from the exhaust and the smell of burning deisel which usually occurs for me when stood in traffic or moving slowly in traffic

Yes, I know the problem. White/grey smoke and a bad smell. It's quite uncomfortable when a Toyota smokes under a person's backside. I understand you.

The stuff above helped me (all the additives) and it got a refreshed ECU too.

From then on, I only put premium diesel in it and there is no problem.

Good luck

A full diesel regeneration should only occur every 300 miles or more at speeds above 40mph taking approx 20 mins to complete.

A dealer can initiate a `static` regeneration.

300 Miles ?? is that a typo?

Deffo not :D in fact my DPF equipped 2.7d Jag was closer to 500 using V-Power

So you are saying that on a DPF equipped vehicle, you can expect to see clouds of white smoke coming out the exhaust for 20 minues at least every tankful of fuel??

I was under the impression that regeneration was only actually occurring if the car was generally not ever going fast - so maybe used primarily in town - and if the vehicle was a 'country car' and frequently driven at 50+MPH, then regeneration was essentially not needed due to other factors keeping the bits clean.

I am simplyfing the words & process there as I don't know the details of this, but the principle of what I have put I am sure I have read as being the case.

I just think I would have notice 20 minutes of 'regeneration' every tankful, but have only noticed something similar on one occasion (just possibly twice) on about 5,000 miles of motoring in the SR

Yeah a DPF does have a `passive` regeneration burning off soot etc during normal hot running but still needs to have a full regen. when the sensors detect its nearly full.

All regenerations don`t have plumes of smoke, my Jag didn`t.

I think you should spend little time on Google instead of arguing the toss with me Hoovie.

[anchorman]

The system measures back pressure in the exhaust so is more likely when the DPF is clogged or you are revving the engine more. So, purging is likely to be a result of either. If the system is clogged then it would normally be oil or fuel deposits hence the questions. No doubt high grade fuel will help keep it clean. The other possible effect is driving style so changing up earlier may reduce the likelihood of it purging.

I'm not arguimg the toss with you, I am having a conversation and making a comment about being mightily surprised that the car does a FULL Regeneration EVERY 300 miles and TBH, don't quite believe it.

Not going to Google about it as it really doesn't matter if it does or or doesn't as I can't change what it does, so why should I bother looking it up and finding information that agrees with you and information that disagrees with you (you can always find the answer that matches what you want it to be on the internet if you look long enough)

[Jozsef]

This can happen too:

Meaning what.... either I`m wrong or lying ?

It obviously matters enough to you the have a `conversation` so why not Google to prove or disprove to yourself ?

And ffs lighten up, gord your so !Removed! serious

[Hoovie]

Meaning that there is so much crap on the Internet I have no doubt I could find an article tha says regeneration is done by hamsters on crack, so there is no point in me googling about this as I dont know enough to know who is right and who is wrong.

I still don't believe that there is a FULL regeneration every 300 miles in the way I understand what a FULL regeneration to be.

[Jamesbelfast]

The DPF regeneration is not time or distance related.

There are two sensors - one before the filter and one after which monitor the differences in pressure. When the pressure differential goes outside the programmed paramaters regeneration will occur.

Will you believe the AA Hoovie ?

[Cyker]

My vote goes to the crack hamsters!!!

But yeah, it depends on a lot of stuff; If you're driving around slow traffic a lot with occasional motorway runs then you'll always get regens, but if you're doing mostly high-rev/motorway then the regens should be fewer.

I'd try the V-Power for a bit if you can; It has much lower soot emissions.

Is the smoking normal? I'm sure the exhaust should not smoke that noticeably during generations?!

I'm wondering if you've got some sort of leak or contamination somewhere along the line which is fouling the filter...

[Hoovie]

So I read the article and I see that AA say that there is SOME regeneration occurring around every 300 miles in SOME circumstances with SOME systems.

I also happened to ask about DPF generation today in a Vauxhall dealership and in a Mercedes Dealership whle checking out new vehicles and they both indicated that as long as you spend at least 20 mins at a reasonably fast speed/rpm each week (e.g. Pretty typical driving for most car drivers who are not in a city 100%) then the DPF gets cleaned up and doesn't need to go through a FULL regeneration process.

I think I am going to market the Crack Hamsters (and maybe Gerbils on Speed for the city motors).

[Steve Hebby]

Thanks all for the info. Ordered some BG244 and waiting for it to be delivered but in the meantime I have put a bottle of Wynns DPF cleaner in the tank yesterday morning and done 220 miles now which included stuck in the usual M62 traffic jams and 50 MPH stretches with no sign of any smoke so fingers crossed I'm wondering if the DPF was blocked which was causing the over smoking. I'll keep you posted.

Might be a good idea to do a bit more beta testing first Hoovie

[Hoovie]

:D

The last few seconds was just the final regeneration I think, after the SMF (Single Mouse Flywheel) slowed down
