Octavia RS FL 2010 DPF failure

regedit

Hi all,
Octavia RS FL diesel (obviously). Car is 2010 so almost 10 months out of warranty. Last week, the DPF light went on for a short while but soon after went off. It came on again this morning on my way to work. I thought I long drive (some 40 km on motorway early in the morning with hardly any cars) would clear the sooth as per manual. This did not happen so I called dealership (Autostation S'ford) on my home to ask should I bring it in or what. Was told to bring it for a spin until the light goes off. I brought it for a lengthy spin (some 70 km)from Newlands Cross to Portlaoise but nothing happened. I was doing between 120 km for at least 30 min steadily after Naas. On my way back, I felt a slight jerk and the car slowed down. The warning sign (the spring like led) started blinking and message engine failure... The car obviously reduced output. Will bring it in tomorrow but one thing bugs me. The DPF gets clogged in start stop scenarios. I live in Newbridge and most of my trips are on the motorway (work in Clonskeagh) with hardly any town driving. Is it safe to drive it some 50 km tomorrow to bring it to dealer to check error. What is the best and worse case scenario that could be wrong?
Surely Skoda does not build cars to start breaking down in under 3 years!

AA experience
We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways.
On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases.
With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed.
There's no evidence in AA breakdown data that the problem's going away – newer car models seem just as likely to sufffer DPF problems if not driven 'correctly' as those built when DPF's were introduced.

All modern diesels have dpf problems not just skodas. But as you said its weird when you only do motorway trips. You will have to wait and see what the garage says hopefully its only something small.

Drive it for 45 mins non stop at 3.5K RPM.

Too late for that. It's gone in limp mode. Air con off, will not go faster than 115v km/h and difficult to even overtake articulated trucks!
My mistake is that I drove it from NX to Portlaoise but let the car cruising rather than trying to up the revs...

Worst case scenario is a new dpf. Most likely is its an exhaust sensor and if they swap it and do a forced regeneration it will be fine. Very common fault on them.

Get rid of the DPF once you get it sorted. I got mine removed on my Caravelle by a lad www.pendleperformance.com in the UK. He has a great set up there. Those DPF's are nothing but a curse. Mine has been running perfectly for the last 30k miles since I got it done. I've only just put it thorough the NCT and it passed with no emission problems. The result was 0.3 out of a max of 3.0.

I know another lad with a Vrs like yours. He ended up blowing the turbo because of it.

DPFs are not tested in the NCT at present.

Get it onto a good level diagnostic equipment and see if there are any fault codes logged...also view the differential pressure.

Had a 09 A6 2.0 tdi a few weeks ago where it was flagging a dpf blocked fault...On live data the differential pressure sensor was reading all over the shop...new differential pressure sensor sorted it out.
once the differential pressure reads to high then the engine ecu defaults into regeneration process for saftey reasons.

If there are no faults logged the differential pressure sensor is reading a constant high then a forced regen may need to be carried out via diagnostic tool.

I had the samp problem in my Superb. Car was out of warranty, it's 09 and dealer changed the valve and did a forced regen. Covered under goodwill warranty as there had been a lot of problems with the valves. 188k later and no other problems tg.

2007 Vrs Diesel. I had the same symptoms but my driving style and journeys didn't lend itself to this. Few bits of research and I found that it was the exhaust pressure sensor that had failed.

€60 from VW, fitted myself and all fault indicators cleared and no more limp mode.

076906051A is the part code. Maybe a forced regeneration could be done also.

6th gear is too high in a lot of cars alright. And the driving eco indicators telling you to change up early are all well and good at saving fuel, but will bollix up your DPF in a short time. Modern diesels need to be pushed at least a few times a week to keep them from clogging DPF's and EGR's. This is contrary to the traditional way of driving diesels.
Sounds like a sensor in your case though, like the last poster. But diagnostics should solve it.
Can't believe Skoda only have 2 year warranty?

thanks guys. brought the car in to Autostation this morning. Got a call back in the late afternoon to say it was not the exhaust gas pressure sensor that was at fault. Apparently, the lead mechanic spent time at it. He connected a laptop and tried to regenerate but it did not work so he'll have to try other things tomorrow. Asked if I would be charged and if yes how much but she was not able to say.

Tea 100, I agree with that. I think 'coasting' n sixth gear did not help m case and I should have probably pushed the car a little bit more. Anyway

...you have to laugh at the fact that a Czech car needs an......Italian tune up.

How very.....60's ?

Is it true that they are tested as part of the MOT in U.K? If the NCT included it, i wonder how much it would cost to get it re-installed

I really don't think so. The tuner I used in the UK told me he is taking DPFs out pretty much every day of the week. He does an awful lot of VAG units.

Got a call back from dealer today. The regeneration process worked (that's what I was told) after 6 -7 hours work. The mechanic hooked a laptop to the car and brought it for a length ride during which he was able to control the errors. Now, the car is back to normal and they still want to fit the exhaust gas pressure sensor (just to be on the safe side) even though it did not come up as faulty. Been charged for 4 hours of work which is 415 Euro. However, mechanic not 100% sure why error came up in the first place so was advised if error comes up again, not to drive the car but straight away bring it to dealer. Waiting for the sensor to be fitted tomorrow. Been told that it was an upgraded version of the sensor...
Not sure TBH if it was due to sensor in the first place but the mechanic got lost looking for a problem where it did not exist or...

Jesus thats some price for labour. Its a pity you dont live down south as I have all that software..

€100+ an hour for labour. :eek::eek:

I think you need to find a new garage too OP.

I thought I'd update you with the outcome. I picked up the car on Thursday from Autostation. Was told that the error codes have disappeared following the regeneration process (it took them six attempts and I believed them as more than 1/2 tank of diesel was gone) and the sensor replaced just in case. They have no idea why this happened. I was originally quoted 415 euros for the repair but when I got at the dealership, the salesman that sold me the car was passing by and asked me what I was doing there. i explained and he asked the service-person to give me a discount. I ended up paying 100 Euro for this repair and 300 for a long time service (annual). I was happy with this and this reinforced my view that not all dealers are only after the money. Hopefully this has resolved issues with error codes

Hi...I currently have similar problem with my 08 octavia vrs....i had engine management light come on and first thing i thought of was dpf..i drive on m50 every day but decided no harm to "exercise" the engine a bit more...got my mechanic mate to cancel the light but came back on... so decided to bring it to main dealer to get sorted...wasn't in limp mode yet. While on way to garage began to get "engine fault..workshop" message..so left it into autostation last week. Got the phone call to say it was dpf problem and they will put in new pressure sensor and do regeneration...given price of about 400e..to which i bit my lip a bit....i should say that the same part was replaced by the same garage in July 2010 with a 2 year warranty...so its 3 months out! I think the car was only registered around June 08 so it was just out then too! so I get another call next day to give more news...above work now done there is a new problem...with throttle actuator...250e for the part and its 3 hours work...so im told overall cost will be about 1000e....feeling a bit hard done by..I will probably look at getting dpf removed..thats if i hang on to the car.

I would take it to Joe Power and get a dpf removal/delete and remap done.
It will feel like a different car and no more dpf worries as those PD engines are notorious for it.

George Dalton

As above, get it removed and remapped by Joe. It will be the best thing you ever do.

Would the insurance co's need to be informed of this mod, in case of an accident? Could you find yourself without cover if undeclared?

From what I hear there are a few ins. co.'s that pass it off or put a slight increase on the premium.

It would be worth a phone call "just to check" not mentioning your details.
Tell them it is the cheapest option and it is a "Eco" map you are doing to your car for economy.

Drummerboy08

It would be fairly hard for an insurance company to prove the car was mapped either way in the event of an accident.

Not that I recommend not declaring it, just saying.

In the event of a serious accident could they not plug in to the ECU with vag com or the equivalent and check the mapping?

As far as I am aware they can and they do.

@op

If you are nervous of a remap then just get Joe to do a dpf removal and delete the code to suit. Forget the remap.

robbiec007

got my car back today...paid 865e for the repairs...and thats with "discount"....having being stung twice on this exhaust pressure sensor warranty been just out I decided to get onto Skoda and raise the issue with them...wasnt expecting anything but if fairness the guy I got talking to agreed with me and seemed genuine in wanting to help me out....he asked me to forward docs to show the cars service history which has been with authorised skoda repair centres...and said they might be able to do something for me...in line of re-embursment of the price of the parts etc...fingers crossed

in relation to removing the dpf...is it not just a matter of time before NCT picks this up?

update from previous post: skoda ireland re-embursed me for 60% of cost of parts which came to 228e..better than nothing!
