You don't need a motorway or fast flowing stretch of road, just a steady speed of 38mph or more for between 5 and 10 minutes.

This should be easily acheivable for most owners hence the reason why the vast majority of DPF equipped vehicles never experience problems.

Exactly, my last dealership was in the middle of Kidderminster, couldn't get out to a dual carriageway let alone a mway to do a forced regen but still managed it around town, as long as your over 50kmh and around 2200rpm it flies through a regen cycle.

I must admit that when I bought the car I was not informed that the car even had a DPF. Not entirely sure who's actually responsible for that information legally however morally it should certainly be the supplying dealer. I live in rural Lincolnshire and the car gets a good run of an hour each way to Lincoln from where I live, however its all back roads and no way does it do over 38mph for a minimum of 5 minutes. I don't live that close to any motorways either. In essence it is actually my partners fault however the short duration between a recoverable DPF and a non recoverable DPF is a bit alarming. Even Skoda are a bit bemused by this.

I'd researched, so I knew what a DPF was and that the car had one, but no mention was made of the implications. In fact, the dealer strongly implied that it was my fault, and I let them know in no uncertain terms that I felt that they were selling the wrong car for their (inner city Sydney) market.

The DPF light in my 08 PD VRS came on last week after a forced emergency stop and stall, followed the manual procedures and the light went out as it should after around 10 minutes.

However after taking it home and parking it up for the night started it up the next day and the Exhaust management light was lit, took it too my mates garage as it was due a 40,000 mile service anyway.

He checked the diagnostics and the fault was due to voltage fluctuation which he thought would have been due to the forced emergency stop and stall, so he reset the light and carried out a full service.

Car was fine until today the Exhaust management light come on again, i have a 120 mile round trip daily to work and home so am a bit worried about driving with this fault.

Any of you guys have any ideas what the issue may be have been reading up on Lambda Sensors issues on here might that be the issue.

the exhaust temp sensors are quite common aswell, these monitor how hot parts of the exhaust are (for regen purposes). a friends leon 170 has just had one replaced due to the pressure sensor acting thus not regenning properly and knackering this sensor. unfortunately there are 3 fitted to the car

Sound very similar to when I had a sensor fault on my 56 PD VRS. I had to wait a week or so for a new part and was told it was fine to drive the car around. I did this with no issues with the dpf or anything else.

Thank you Mr Bond and PSM

Had my mate replace the exhaust sensor today all seems fine and well with my big diesel mile muncher.

surely this 38mph thing is nonsense. If what is important is the exhaust temperature, all you need to do is to get the engine's RPMs up, even if it's parked on your driveway.

or am I missing something?

Sitting on the edrive wont work, I guess it puts insufficent l;oad on the car to create the burn temp required

My dealer didn't mention anything about the DPF when I bought my new CR VRS, however having been a member here for ages, I read about the perils.

However, I am fortunate in that my car is on the motorway everyday and am able to travel at 75 mph daily, so never had a DPF problem.

Have parked up and heard the car regen though, so that was ok.

I noticed the local Skoda dealer has DPF leaflets on the main counter explaining what it is and how to deal with any issues which seems sensible given the potential issues with the system.

Your missing something.

It simple, if the car isn't doing 38mph or more then the computer won't start the regen.

My Exhaust management light came on when I left work on Thursday..straight to my local dealer..they put it on the computer, turned out it was the DPF filter.

They replaced it under warranty (should have cost £29, plus labour) It took longer to do the paperwork, than replace the filter.

Don't know where your dealer got that price from !!!!!!!!!!!!!!!!!!!!!!!!!

If you can get a dpf for £29 I will take 10,000 of them off you hands.....and be a rich man by the end of the year

They wouldnt replace the DPF filter for £29 plus labour, sounds like a faulty sensor. The DPF has a retail price of £1600 plus labour to fit it.

Not seen the DPF light on my remapped PD140 Superb2, my weekly commute is 144 miles each way (there on monday, back on friday) and consists of a large chunk of M25. Last night my car spent 2 hours crawling along the M25 and its much the same going to work. Once down in Dorset my drive to the office is less than 1 mile (I could walk I know) so I do 6 miles of driving at less than 30mph for the rest of the week. My Superb is now on 26K miles, and so far so good.

Ooops, sorry folks, just read the invoice , and it was the sensor :(

My PD170 has been into garage three times in last month with DPF problems, the first time to get a forced regen because my engine management light came on even though my DPF light has never come on and for which I was charged, only to be finally told that there was a prob with the pressure sensor.

They replaced the sensor only find that it wasn't that either and have now referred the problem to Skoda Technical Dept. I am now in a bit of a dialogue with Skoda Customer services as the garage are now saying that my DPF light was on the first time which is catergorically not the case. I wasn't convinced that the car needed a regen but was informed that was what the diagnostics were saying.

Even though I love my car, my confidence in it has taken a battering, and my confidence in the dealerships is now vitually rock bottom.

From my experience, I would recommend to anyone with even a hint of a DPF problem, to ( A ) Request a copy of the diagnostics printout from the workshop,

( B ) Contact Skoda customer services and get a case file opened so that any problems can documented by them, ( C ) Document any conversations and correspondance and keep all receipts.

To top it all off, someone in the garage reversed the car into a bollard, creasing the bumper and then saying that they would mend it with filler!!!! The car is going into the garage again to get a new bumper.

I am not currently a happy driver!!

Shame the Germans didn't invent the DPF in the last war.

The U boat fleet would have been fu**ed.

I've read in various places that CR diesel engines like mine are less likely to have DPF problems.

Does anyone know if this is true, and if so what the reason is?

IIRC, the DPF on the CRs holds 33% more ash.

The DPF catches soot and converts it to ash. Theory goes that the latest engines are cleaner so produce less soot for the DPF to handle, thus they are less likely to block.

The latest on this is that Gem got a call from Skoda today saying they were not going to contribute to the cost. She complained that the day before it all went horribly wrong the car did a full regen so how could a day later it go into limp home mode. And the fact that the filter is only 90% blocked so why cant they do a forced regen. They said they would get back to her so fingers crossed.
