Hi,

my 57 plate superb has had some lights come on, one looks like an engine, one like an exhaust and one a looped line.?

also the centre display shows "deisel partical filter instruction" and "emissions workshop" when i start the car.

my mechanic friend has refilled the "pig p1ss" in the boot but he cannot clear the codes.

he has vag-com diagnostics which will bring up the issues/ codes but there is no botton to press to do the reset.

 

i have spoken with my local skoda main dealer who was surprised that the car had "ad blue" as he didnt think skoda had this system. doubting him i spoke with another skoda dealer who knew about the ad blue, but would not be able to reset it as then they are libable  but he did say that the tank (in the boot) should reconise that its been refilled and therefore reset itself, to which it hasnt in the short jornrey home,,

 

any ideas guys would be much appriciated, or am i knackerd

adblue is the wrong fluid.  These are old-tech DPF systems which have to use a very expensive fluid. 

There is another thread here at the moment with a link to a pdf in it which describes the system fitted to your car.

Here is my post:

thanks for the reply, jimbof. some intresting reading there.

but doesent really anwser my question on how/what resets the tank when it gets re-filled

Which codes is it reporting?

Is it complaining about the additive level or telling you the DPF is still clogged?

I think if you ran it without fluid long enough the DPF might be clogged to the point of needing emergency regeneration or worst case replacement.

My old Peugeot used to "count" the amount of fluid injected, so that did have to be reset (as there was no level indicator in the tank).  But looking at the diagram in the PDF (page 12) you can see there is a level sender in the additive tank.  So just filling it up should be good enough (unless the sender is broken).

So really the question is what is the code reported...

You can also see on page 19 some pictures of what each component looks like and a bit of the info about their interactions / connections.

thanks again for your help Jimbof,   my mechanic has said that he has refilled the tank, using the fluid from "tps" (i think they were called).

but all 3 lights are still on. he has said it needs to be run for at least 40mins on a motorway/ A road to get it to burn all the soot off.

but i am now worried that its now more to it as it has been run for about 5000 miles with the "loop" light on (long story) for about 1000 of those miles wiith all 3 lights on. the car is on 97000 miles now.

i dont belive from what he said that there doesent appear to be anyway of clearing the codes(i dont know what they are sorry)but i supppose there is more to this than re-filling the tank

In your opion have a damaged the DPF?

i have booked in with Skoda for next saturday so will have to see what they say, but im not holding my breath :wonder:

I'm not a mechanic myself just an interested amateur;  it sounds like he is telling you that the DPF is clogged (hence running it for a while at higher speed to help burn it out).  That is fairly standard advice for clogged up DPFs and can clear them out sometimes.

You probably should do that and see if it works.  

 

I believe just filling the tank is enough if the DPF isn't clogged.  I don't know how long you'd have to run it for to clog it without fluid - it depends on driving style / journeys.  If you were doing short journeys for 5,000 miles it will be quite sooty...  But to be honest it is all guesswork without knowing what the codes are.  If the DPF is clogged, then there isn't anything you get to clear on the computer... you need to clear the blockage first.  There are companies who can "code out" the DPF and fit a straight through pipe or hollow out the filter - if your DPF were stuffed you might be better going down that route than trying to get it fixed.  Though I don't know if it is a service available for this engine.

 

If you want to investigate it yourself you need to work out the codes.  Maybe see if there are any members local to you who could read your codes using VCDS.  Where abouts are you?

Don't know how many times to thank you jimbof, when the light was on, it was mainly fast a roads or motorways. I will contact my mechanic mate (who has VCDS) and see if he can remember the codes.

I'm in basingstoke , Hampshire. If the dpf is knackard then I will probably go the route of getting the stupid thing removed.

Is there any repercussion to this

Cheers again

My guess is that you have stuffed up the DPF by driving for a further 1000 miles after the 'do something now' trio of lights came on.

Ah, oh well, just seeing if I can find out how much it is to remove the whole thing.

I suppose I will have to wait and see what skoda say on Saturday :-(

Well good luck with it hope you get it sorted.

Worth staying away from DPF cars if at all possible...  Once bitten twice shy!  They have no benefit to the end user (other than a lower tax bill) - but you've probably paid more than that over the life of the car in the increase in vehicle purchase price and then ongoing maintenance. :(

What are the ash level readings in MB68?

I've always wondered what would happen if you set the level to zero as you would when replacing the DPF.

It was a company car so didn't matter as the company were paying for it all, that was until I left and got given the car, so a bit stuck now lol

I can see your point, but I'm no mechanic, will ask skoda on Saturday, and if my mate is working I will take it to him and see what has been reset

lol that is almost how I got stung... my dad had a 307 peugeot which had been fully serviced by his company and I picked it up for a "song"... and promptly cost me £1300 as failed DPF system was resulting in fuel in the oil which in turn lead to turbo failure and a DPF full of engine oil... :(

GREAT....................

If it goes then I will part it out, it didn't cost me anything, so any money would be a bonus

I don't think the VW's (and hence the Superb) have the same failure modes so don't worry about it too much.

Will have to wait till Saturday to see what skoda have to say, considering they didn't even know it was fitted to their cars could be an interesting day lol

ok, update, just picked the car up from skoda who said they have cleared "all" the faults and that were all intermitant. 

was told to take the car away and if the faults / lights re-appear then to take it back. 

Big shout out to basingstoke skoda who didnt charge me for this

 

this is what they found (i have no idea what all this means)

The two faults indicate a faulty G450 exhaust sensor or faulty DPF. If you are very lucky, they relate to the time you were running without DEF and that time was short. Fingers (and everthing else) crossed.

thanks for the reply, so what does that mean, in very simple child like terms please

right update,

since Skoda turned all the lights off all has been good until last wk end, all of the 3 lights re-appeared.

i call skoda who said that i should take it down the motorway to see if it would "re-gen itself" 

so down the motorway tuesday night and wednesday morning and all the lights went out 

to cut a long story short, i booked the car back in with skoda yesturday to have it checked over (as im off to france sunday 27th) and they came back that yes it did re-gen there is to much ash in the DPF that cant be cleared.........., so £750.00 lighter for a new DPF i pick the car up tonight , drive it a couple of miles turn it off, get back in, couple of miles later, the car coughs and spluters, makes a horible sound and now seems to be in some sort of limp mode.

back to skoda in the morning to see what has happened

 

any ideas guys please

went to skoda this morning and apparantly the turbo hose had blown off due to the new pressure the exhaust makes, they showed me the pipe that had come away (underside of car, right at the front passenger side about 2" dia) it seems to be fine now

 

does this seem right?

 

cheers
