I only offer opinion but I would expect you will be fine. I can get a regen out the way in 5 minutes and certainly less than 4 miles. When you know the signs of a regen starting you can temporarily alter your driving style for 5 mins. I just drop a gear and keep the revs 2000 to 2500. Economy doesnt suffer and its all over and done with in no time at all. Alternatively do nothing and it will probably regen fine anyway. Mine takes a couple of miles more and a little longer if I am in 5th at say 1700 rpm.

The CR can regen even when idling. I would expect the regen to be shorter and better managed than mine as the CR system lends itself to better post fuel control.

Thanks for the comments and based on this

On mine once the blue temp light goes out it can start. The blue light even in winter goes out after about 1 mile. I like it when it starts a regen straight away as the car warms up quicker and I get all toasty as the heater works better sooner than it otherwise would do.

Normally the car isnt properly warmed up until several miles has passed. With the regen kicking in it gets warm really quick. The blue light to me doesnt mean its properly warm, just not so cold your going to damage anything by revving it

I think I should be OK.

Going to work a regen would probably only start near the end of 60-70mph part but coming home engine should be at operating temperature, particularly if it does a fast warm up routine, with 4 - 5 miles dual carriageway to go. If I am aware it is doing a regen I can drop to 4th and can carry on for a couple miles to next junction so it ought to complete plus if regen can carry on at lower revs still 2 miles of 30mph to home roads where I can keep in 3rd to keeps revs up a bit.

Time will tell.

If I am every lucky to get a more local job TDI will turn out to be the wrong choice.

Oddly enough mine started a regen tonight 4 miles from home. It was on a slow B road. I dropped to 3rd and kept the revs around 2000 ish at about 40mph sometimes a bit more. It was all done and dusted within just a few miles and 5 mins. Its very bizarre. My MPG is fantastic when it regens. No idea why other than the fact the EGR valve closes for regen. It would appear holding revs is more important than speed or load.

This mpg thing is strange. 3rd gear over 2000 rpm and it showed 98 mpg on the flat.........maybe the trip gets all confused during regen. Its one of the ways I know regen has started.....the mpg gets better.

My car did a regen the other night and for the second time only (both with the new engine and injector remap) I noticed it happening The car did not go into stop start and hunted at idel between 1000 and 1100 rpm.

By the time I was home about 3-4 miles the regen had finished.

It seems to me that the Greenline is able to regen a lot quicker, I wonder as Raisbeck has said the Greenline's regen process is more frequent?

I have a feeling the Greenline DPF is smaller than many other cars. I will have to check but if I recall the DPF on my Greenline is like a round canister as opposed to the oval section CANISTER you often see on larger cars. May explain why it fills sooner and is quicker to clear. When I get the chance I will have a closer peek. Its really hard to see as the back of the engine is shrouded in all sorts of gubbins. My mpg has been mediocre for the last few tankfuls .......low to mid sixties at best. I changed the fuel I use today. Up to now its always been Esso. I filled with Shell today (only 1 bar showing on the fuel level!). Same journey home, same route, same outside air temp. It did 69 mpg....... I think I will be using Shell now. Maybe their winter diesel has a bit more oomph in it.

I have a Octy VRS CR & have never seen the 'regen' light despite some fairly short trips. I've tried to run the car on V-Power diesel as much as possible which I think may have helped as it's not meant to produce any soot as it's made from compressed natural gas AFAIAA

I've done 13,000 miles in it now (it's nealy 1 year old) and the econ. just keeps getting better & better...very easy 46-47mpg without being careful & I've even had 64mpg on a m'way run at 60-65mph. I'm hoping the Fabia VRS improves as it's currently giving 32mpg average with a best of 40mpg on a 60-70 m'way run...it's nearly done 1000 miles so I'm sure it's still tight.

Does the Octavia use the additive from a separate tank for Regen ? Or is it the same as a Fabia ?

HI Doug I cannot seem to find the v-power diesel here I have a shell garage but they have no v-power diesel I want to use this in the new fabia cr tdi1.6 105bhp or should I stick to shells regular diesel

My Greenline is currently running on Shell fuel saver and I do not seem to have a problem. I am surprised your garage does not sell the Vpower I put some in mine by mistake, it did not seem to like it but then I did not give it two tank fulls of the stuff.

Shell fuelsave :thumbup:

Could be coincidence but my mpg is up 2mpg and the regen on fuelsaver for some inexplicable reason is shorter to complete

Up to now I have always used Esso. This isnt another fuel debate but when you do over 500 miles a week as I do, you notice small changes that arent placebo.

I am almost back to summer mpg figures.

After much experimenting I find regen is most effective and the time it takes is greatly reduced by using more revs at a lower speed. Ideally 3rd gear at around 2300 rpm. Mind you 3rd gear in mine is like fourth in a standard Fabia. Of course 4th or 5th on a motorway would be equally as effective imo. its just my regens have a habit of occurring on slower roads.

On the subject of fuelsaver, the gossip and hearsay is that its standard fuel with extra ethyl hexyl nitrate to up the cetane rating. Maybe some extra detergents as well. This is pretty much what is in Millers Ecomax if you believe other posts.

I usually cannot tell when I am having a regen and have up to now only used Shell Fuelsaver.

I am now wondering if fuel choice makes a difference to regen and while for non DPF engines it does not matter too much which fuel you use for DPF engines it does.

For those of you who are/not having problems with regen what diesel are you using?

Hi

my wife has got a '58 greenline and up and till now we have loved her (rhoda the skoda) but we have had a a few warning lights appear on the dash including the light that tells us to go for a short trip to regen(?) the dpf(?) but now it has got worse and the regen doesnt work anymore and the garage says we need a new dpf filter, is this correct? sorry I sound vague but I dont drive the car as much as my wife

also millers ecomax fuel additive seems to help stop soot up the dpf

I use the cheaper (non V power) diesel from shell and my little local guy who is a lone pensioner manning the pumps in the village.

Only ever noticed the regen working once when the stop-start didn't cut in. Glanced down at the dials and saw it ticking over at 1100 rpm.

Other than that, never noticed it at all.

I have a Fabia Greenline. So far it regens regularly at around 110 miles. Its very obvious to me when it does this. The power drops off a little and you get a more throaty exhaust note. I havent ever had the DPF light but I do long journeys every day. The only fuel that extends the DPF regen interval that I have discovered is Total excellium or Shell V Power. They just produce less soot I guess. Mine has done 30 000 miles without a hitch and regens exactly as it always has since new. If yours isnt regenerating it may be the differential pressure

sensor. This is located on the LH side looking at the engine and has two hoses that lead down to the inlet and outlet of the DPF. Failure of this switch would cause a problem regenerating and may cause a clogged DPF. Its worth checking anyway. DPF should last the life of the car, early clogging could occur if the garage hasnt been using 507 spec oil. This has virtually none of the ash that can prematurely clog the filter.

Alternatively if you are getting other lights it may be your EGR valve isnt working right or a dicky injector causing your DPF to clog.

The regen system on yours (and mine) is quite different to the new Greenline II. Generally speaking it needs more of a journey than the Greenline II as regen is limited by the cams on the unit injectors. The new Greenline can inject as much post combustion regen fuel as it likes as its got common rail injectors.

Ecomax is just 2EHN that increases the Cetane rating and Naptha that cleans injectors. Oddly enough Total Ecomax smells exactly like Millers... ;)

Is the sensor upstream of the DPF ok? We had the same problem with out CR diesel Golf but the dealer replaced the probe and regened the DPF and it has been fine since. Worrying thing for me was that the car is on the motorway at least five days a week so it isn't the short journey syndrome causing the problem.

On the fabia with the pd engine there are two sensors combined in a single unit. They measure inlet pressure against outlet pressure to determine restriction to flow. It's mounted just under the engine cover. Just follow the hoses from the dpf.

Many thanks for the help :) ... my wife is taking it to another garage(a main dealer this time) problem is its 30 miles away as that is the closest dealer we have. The car is just used for short journeys and is used constantly as its a work car. Every time it goes in a garage she loses a days wages plus garage charges...thanks again everyone...keeping our fingers crossed

Hopefully it's not a new DPF, but with other lights coming on and going (?) I suspect it could be a faulty sensor or something else.

I also seem to remember under certain conditions a main dealer can clear a DPF.

Hi,

I find this thread on the DPF really useful. I come from a Opel (Vauxhall) Zafira 1.7DTI whose DPF decided to go on strike on New Year's Eve without notice. That is, the warning light never warned me because, as the garage guy told me and contrary to the user's manual, Opel decided to disable it since it could concern the less experienced drivers... So I am relieved to read that Skoda warns us before it's too late!

On my Octavia 1.6TDI (brand new, I just passed 1k miles), I never realized the regen started, at least until yesterday: after a 15mile drive I stopped and I could smell the typical "Eau de DPF" perfume. And if the regen is done approx every 120 miles, I have to say that I've never been aware of that.

well its 120 miles..ish for my Fabia. The Octavia with the CR engine may be different.

I thought my regens were regular, and on a few I got the "Eau de DPF". Now I am back to random regens and no smell. I have just done over 400 miles of city driving and not noticed one regen.

My elegance 1.6crtdi 105bhp done 1,800k now never been aware of regen, however doing a 500 mile round trip thursday down to bassingbourne so will see :thumbup:

Well after losing 2 days wages and £170 also worse off (for replacing an incorrect diagnosed faulty pressure sensor, stay away from Rayleigh Motorist Centre in Essex as their customer service is useless (unless you like being called mate in every sentence :wonder: and they dont know what they are talking about as they wanted my wife to pay for a new DPF +£1000), well its been fixed, the skoda garage in writtle, essex (that she normally goes to for her servicing(problem it is over 20 miles away but their customer service is excellent) has fixed the dpf problem and both warning lights with just a regen of the dpf (god knows what those guys in Rayleigh were doing. ) and as all you guys were saying :) , the DPF will last the life time of the car

I too have the Fabia greenline estate 08 plate and have had the dreaded engine light on. Tests show that it is the exhaust pressure sensor so I have bought a new one for £52. I am struggling to locate it under the engine bay. Any pointers for me?

Edited by snacr63

I have now located the exhaust pressure sensor. It is to the left of the top of the black plastic cambelt cover on a silver metal bracket to the left hand side of the engine when looking from the front of the car. It is not immediately obvious because it faces toward the bulkhead. The T30 screw which secures it faces towards the top of the cambelt cover and I had to loosen it by using a T30 screwdriver bit and a small adjustable spanner. The next problem were the clips on the 2 vacuum pipes which I opened using a small mole grip which held them in the open position. I was then able to move them down the pipes and take the pipes off the sensor. Refitting the replacement was easy and the total time was about 15 minutes without knowing how to do it.

Once fitted the engine was started and the engine warning light went off within 5 minutes. The sensor does not have to be recalibrated once fitted.

What i find amazing is that people on this forum talking of being charged £160 at a garage for this repair. The part cost me £52 including postage from my nearest Skoda dealership. Therefore, why are we being charged £110 labour for 15 minutes work which equates to £440 per hour!

That's the dealers for you we need to find independent
