I have a 59 Octavia VRS CR diesel. 50000 miles

I do about 50 miles a week town Driving + about 260 miles cross country A road enthusiastic driving across mid Wales.

As such I did not think that I was an obvious candidate for DPF issues

2 weeks ago the DPF warning light came on . At the end of my journey I looked up the force re-gen procedure and decided to try it on my next journey. Before I got the chance the light went out. I did it anyway. Over the next 2 weeks it kept coming back. Every time I tried to clear it while driving I could never get it to go out but at the end of the journey it always disappeared and then stayed off for a few days.

It always seemed to come on during my cross country blasts rather than during city driving which never made sense to me.

I started to suspect there was something odd going on but before I got a chance to do anything about it it got worse.

Today it came on again and before the end of the journey the flashing glowplug light also came on which I gather is not a good thing.

I have read through the threads on this forum but they seem to all relate to the older PD diesel.

Does anyone know anything about issues with the CR diesel. Is this going to cost me a new DPF. or are there other possibilities such as a sensor fault that seems common on the PD. Should I consider DPF removal? Again not much on this for CR diesels.

thanks for any advice

Now you've had the flashing glowplug light the car will have logged a fault. Did it drop into limp-home mode too (reduced power)?

Do you or anyone you know have access to VCDS so that you can read the code? If not it'll be a trip to the dealer.

The sensors for the DPF are the same as the later ones used on the PD so there is a high possibility that this could be a faulty sensor preventing the DPF from regenerating properly.

I always said that DPF issues would begin to appear on the early CR engines at some point as they begin to reach the five+ year old mark.

Worse case scenario a professional DPF removal is around £450.

Exhaust pressure sensor, that's a good one for going. Already had mine done last year and the car had only done 35000 miles.

Yes dropped in to limp mode. I forgot to mention that. I don't have vcds. I have A Bluetooth obd2 reader and torque for android. That shows a fault of p2463 - power train which equates to dpf. I will have to contact the dealer. I gather this occurs when the loading is 75%. But I did not know that at the time and drove the rest of the way home 10+ miles. I gather if I have hit 95% it is now new dpf time. Can't help thinking a red light of some type might have been more appropriate under the circumstances.

Jason,

From what I've read and based on expert opinion, A road blasts are not the most effective way to keep the DPF clean. A constant motorway run of 20 minutes or more, above 2,000 RPM driven regularly (at least once a month) is the best way of keeping the DPF healthy. I hope this helps, and best of luck mate.

Cheers,

Rob

I am sure you are right but I would have thought my typical driving pattern was adequate.

And now it turns out I may have been right. Just had a call from the garage. Looks like exhaust pressure sensor failure. They couldn't get the fault to clear they couldn't get the fault to clear even after a forced regen cycle. Which meant either the sensor or a new (/removed:o) dpf. Fortunately the former. Replaced the sensor and bingo fault gone. Never been so pleased to spend £135.

Thanks for your good wishes.

Well, that's v good news for you and reassuring for the rest of us with a CR. hopefully you'll have many miles of trouble free torque

Very glad to hear that, great result. I guess I stand corrected on driving style for DPF health, but most expert opinion seems to think that regular prolonged motorway driving is the best way to keep to clean, perhaps not the only way though.!

I have heard of those exhaust sensors packing up on Octy's and Superbs, probably on all VAG motors. Hell of a lot cheaper than a new DPF though.

Best of luck,

Rob

have an 09 cr vrs had same thing happen to me as well. was the sensor as well . I remember a thread about a malaysia or usa sensor one prone to going and it gets replaced with the other(cant remember which one ) one & no problems

I was aware of the sensor issue but just assumed that by 09. With the advent of the CR they would have sorted it out. I guess not. It would not be so bad if they failed completely rather than giving a false high reading that tricks the ECU in to telling you that you have a completely different and eye wateringly expensive fault. Skoda dealer told me ballpark £3000 if it needed a new dpf. They also did say though that they haven't yet had to replace one on CR which is reassuring. Said they had always managed to clean them even when over the Max threshold. Also reassuring

I see AP Automotive (of Telford) have 'liked' one one of my posts above. I feel bad now because at no point in the above thread have I credited them with actually fixing my car for me ;o) My comments above regarding what "a Skoda dealer" told me was the local main dealer Faintree but ultimately due to a persuasive recovery service "Dream Finish" and by virtue of being open on a Saturday it was AP who ended up with my car and diagnosed and fixed the problem.

So there you go. Credit where credits due. Its just a shame I am 130 miles away and can't make it back to pick it up till Saturday. This is the first time in about 15 years (309 gearbox failure) i have been without my car for more than a day (excluding holidays) and I think I am in withdrawal.

What a poor design of car that seems to keep causing all these issues , my vrs 09' ltd edition has recently had an exhaust sensor now 2 months later its back for a DPF sensor ..... Tempted to get rid already after a year , skoda you really need to do better.

To be fair, it's a VAG issue not a Skoda one.

Well until you can get a Skoda with a non-vag engine, that's kind of irrelevant.

aim having a 10 plate  octavia estate 1.6 tdi cr se got the brouche in front of me

and it says dpf dieselparticulate filter ispart of the exhaust system responsible for cleaning the engineexhust gases before they enter the atmosphere

the dpfcatches soot particles emitted in the exhust gas and itwords inconjunction with the catalyic converter which reduces the

amount of harmful gases entering the atomosphere the dpf must periodcally be emptied of thesootparticles a process known as

regeneration this involves elevated exhaust system temperatures  a driving style is required during regeneration where  a constant

vehicle speed above 37 mph must be maintained this does not always suit customers who make frequent short journeys or experience

stop/start driving or drive with in inner-city or urban areas i shall keep a eye on my car

I had a similar Issue last year with my CR. Long journeys commuting at weekends 3hrs plus. No DPF lights on dash, DPF clogged completely and back pressure caused turbo pipe to pop off. Luckily covered by warranty but is was touch and go. It was thought that the DPF sensor and exhaust sensor had failed but not light on dash illuminated. Part numbers have since been changed which says a lot! :-/!. No problems since thank god. I retreat getting the petrol. DPF is To complicated.

Hi @Briskodian  , Guess I share the similar problem that you have had with DPF , 2 hours ago posted it here in skoda rapid section http://www.briskoda.net/forums/topic/291616-glow-plug-symbol-flashed-engine-misfiring/ , it all started with glow plug flashing , which i got check at the service center today already and was assured there is not an actual problem just the ECU software was upgraded .

 

But now an hour ago i decided to give it more try and went for a short drive and to my surprise glow plug problem occurred again and this time it happened in 2nd and 3rd **** , symptoms are the same ( symbol flashes , engine stops and i pull over ) been lucky no mishap happened so far and now  I am really nervous. Decided to drive a  bit more further something i new i noticed , the DPF symbol flashed this time along with glow plug on , i had less choice but at least to get home so decided to switch on the engine again and this time DPF consistently stayed on even with batter sign (red) , managed to get home and noticed the DPF comes back on every restart .

 

I am bit frustrated at this time as I dont understand what the heck is going on considering i already showed the car to Skoda and nothing evident was found .

 

Note: i didn't even understand these symbols its only when i open the manual and check and read more on the internet to understand better .

 

PS : I drive very short distances every day ( my office is about 2 km's away from home ) it's only once in 2-3 months that go for long drives , and i understand I should go for 20-30 min consistent drive over 3000 rpm to force dpf regeneration but not sure :(

Does anybody know how often you should take a car with a DPF filter for a run if you don't do a lot of miles?

There are too many variables to answer that question easily.

 

A car doing low annual mileage can have no DPF issues. Even short journeys can allow the DPF to get hot enough to perform passive regenerations.

I read a report from the AA a while back stating that they were attending an increasing no of dpf related incidents with vehicles that were doing motorway runs at 60mph in 6th. The exhaust was not getting hot enough to do passive regents. I suspect the engine needs more load to get everything up to temp.

My 2007 PD170 vRS spent 90% of it's time on the motorway. Towards the end I was seeing the DPF light once a fortnight.

 

The wife's 2008 PD140 Scout trundles to her place of work each day and we've never seen the DPF light.
