Hi There, I have an issue i could really use some help on. I posted a couple of weeks ago (link below) about changing my DPF Pressure sensor due to a P2455 error. I was informed that the sensor needed adapting with VCDS and i was given a Ross-Tech link to the procedure. BIG nick helped me out with the adapting, i drove to his and fitted the new sensor and let him to get to work (the car was not started at any point). My car came up as UDS so we followed as per the instructions: UDS Protocol (G450) procedure Key ON, Engine OFF [basic Settings] Select Adaptation of diff. pressure sensor particulate filter [Go!] to activate the Basic Setting. After the result of Finished Correctly appears click [stop] Select Resetting of learned values of difference pressure sensor [Go!] to activate the Basic Setting. After the result of Finished Correctly appears click [stop] [Done, Go Back] All was going well until the highlighted step. This option did not appear exactly as written like everything before. Instead it had the option "Adaptation of diff. pressure sensor particulate filter". We cleared this and another option sounding remotely similar and clicked done. The issue seemed fixed but a couple of days later i get a P2453 "DPF Differential Pressure Sensor Circuit Range/Performance". I can clear the fault but it reappear at start up sometimes, the car otherwise drives/act normally. I am thinking about buying another sensor, a more expensive one (original new sensor was £20 from ECP) as it sounds like it could be just a duff sensor but im worried it could also be the fact that VCDS didnt have the same options. Does anyone have insight into this?

Thanks, i used the owners map to message someone more local but thank you for the kind offer. I'll give it a go, worst case is i bust a £15 sensor so no harm in trying.

If thats the case ill have to find a VCDS owner on here and change it there, should be too difficult, do i fit the sensor and then without turning the car over follow thes steps posted in the link above? Thank you for the details, very useful.

Afternoon, I am about to change my DPF Pressure sensor in the hope that it fixed the P2455 error on my car. I have seen some anecdotal posts on this forum saying i need to reset the new sensor with VCDS or something along those lines, can someone confirm this is the case or if simply fitting the new sensor and clearing the old faults will be enough. Thanks

Eml light came in n today with p2453 code. Almost certainly the sensor so picking one up from euro car parts tomorrow for £38.

Thanks. I went for an Italian tuneup and the light did dissapear but I think for peace of mind I'll order a new one on Thursday when I get paid. The only difference between p2454 and p2453 is circuit low and implausible signal at the end. Both I think mean the ECU thinks something is up.

Hi all, This morning on start up my 1.6CR Octavia showed the above light along with fault code P2454 - Diesel Particulate Filter Pressure Sensor "A" Circuit Low. Now forgive me if im wrong but does this just mean i need to regen the dpf, or soes it mean the sensor that monitors the ash content is dud. If its the former then fine but im a little annoyed as i think its only the result of me trying to be extra frugal with fuel (high 60's for the past two tanks) as for 5 months before i never had any build up as confmed by VCDS. If its the latter then am i right in thinking its a straight forward job to replace the sensor and its just two vacuum tubes and a connector? Im welcome to any other ideas too.

Just an update for anyone in the future with a similar issue. I was persistant and i managed to get a full repair and a service thrown in F.O.C. Best of all i got it done whilst on holiday so there was no hassle. The car has done 107,000 miles but this is irrelevant as Skoda state that the EGR is NOT a wear and tear item and is a "life of the vehicle" component. This is reflected in all their warranties. Of course the reality is a little different but this was an important point when forcing the garage to admit liability for the fault under SOGA. The car drives much smoother and seems to pull more than it ever did.

I don't think the milage is entirely important to answer the questions I posed but its safe to say that it is well outside any warranty from Skoda. This has been purchased from an independent garage so any claim will be against them. Thank you for your input; I'm intrigued about the software update. Is there any information online regarding it that you could point me to? Thanks

Long story short; my EGR valve is clogged up and my extended warranty doesnt seem to cover EGR valves. The garage agree to take a second look but I'm not overly confident they will accept liability. I bought the car in January so I believe I have a pretty strong claim under the Sale of Goods Act against the garage I purchased it from. If it comes to it, I am prepared to push this through small claims court. Because it hasn't been 6 months since purchase, the burden of proof lies firmly with them (hence why my case is so strong) however i think its still worth me putting together my case. My questions are: 1) Is there an official life expectancy of an EGR valve or is it a 'life of the engine' part? 2) Is there a need to replace rather than just clean? 3) Do you personally feel this is classed as a wear and tear item such as tyres and therefor should not be covered? The reason for these questions is that if it went to court, the decision is usually based on the balance of probabilities and what "average consumers would deem reasonable" so the more opinions i get the better idea i will have.

I have the above fault appearing pretty much every drive on my 1.6CR Tdi. It can occur 1 minute or 1 hour into a drive and is always accompanied by the glow plug warning light and sometimes the engine management light. The car goes into limp home mode until i next start the engine where everything functions as normal. The car is booked into a diagnostic with the garage i bought it from (only 5 month old) on monday but i need to drive approx 50 miles each day until then. At the moment im having to use Torque on my phone to delete the faults any time i need the acceleration (merging into an A road etc) but the rest im taking easy. Im considering taking it for an italian tune up, does anyone advise for or against this with this particular engine?

I imagine its something to do with engine management linked to the DMF being protected from excess strain. Either that or you are just noticing Turbo lag. Just two possibilities.

The oil is ACEA rated C3 (the strictest standard currently) so strictly speaking is to the same standard as so called "premium brands". Having worked in the factors business and attended a few training days with Mobil/Comma (before their de-merger) I guarantee at least 50% of the price of oil is to pay for marketing, sponsorship and shiny labels. If you don't mind paying for this then by all means buy castrol etc but the above oil will serve you equally as well as proven by its rating and approval by vw for meeting its standard.

Rang all the garages who carried out the services above. All confirmed that they had not done the cambelt so rang with Skoda UK who just said it would be offered with the 4 year service but if declined it would not form a gap in the service history. They said at 115,000 miles it must be done with no specific time limit. So looks like i shall be getting it done next service. As its not due as per the service schedule; im covered by my warranty for now so im not overly concerned. Skoda gave me a price of £449 inc VAT for waterpump and cambelt on top of normal service charge. Another garage quoted £364.61 inc VAT for cambelt and waterpump bt im going to use discount from my old work to get decent parts and some old contacts to see how much labour can be.

No, the car is from a car supermarket type place but has a 3 year warranty. I did specifically ask in the process of buuying the car the service history mentioning i wanted to make sure major service items like the cambelt had been done. Ill see what the dealer who carried out that service say although im not expecting them to tell me much more if anything than Skoda UK. If they cant then ill bring it up with the store i bought it from that the item had been skipped. This is theyre a family who own a lease company, a car megastore and a vauxhall dealership. The car megastore sells cars they take part ex from the vauxhall garage and their ex lease cars so this car is one of their ex-lease cars so they should be responsible for any omissions in the service history too!
