pretty sure anything which can potentially cause fire is recall worthy.

 

Like petrol or diesel road fuels?

 

Li-ion batteries?

 

Without internal combustion or electro-motive power we are left with bicycles and beasts of burden as modes of transport which are not potential fire risks.

Hey Fixitsan, have you tried to do a factory reset of windows up and down so they know their correct position whether up or down and where they should be in the correct phase.

Dan

Yes I tried that

 

I think I've resolved it...

 

If I assume all the windows were down because I sat on the key lastnight (holding down the 'door open' button), and there was a bit of rain lastnight, then the drivers door switch could have got wet.

 

I've opened up the door switch to get to the PCB, and the tracks are corroded under each of the front buttons. I've cleaned the tracks/pads and they work normally again. These are the sort of tactile switches with a conductive rubber pad which shorts out a grid of conductive tracks to make the circuit. I'ld say they've been wet before too.

@fixitsan, did you replace the wraparound pop-on heat shield too? I only ask as that original one looks decidedly knackered and will probably do less than a t-shirt wrap to protect the new sensors! 

Mind you, knowing VAG, it’s probably on back order and £110… plus VAT! 

Hehe no its actually survived, is still flexible and the pop studs work fine.

 

Hi I have a 2017 Superb Diesel LK and I had a cam belt change at a dealer about a month ago.

 

2 weeks later I get a engine light on the dash and after using OBD11 it pointed me to the DPF particle filter pressure sensor.

 

Semi melted mess as you can see in the picture.

 

If I changed this sensor do I need to do anything else? I can't see a setting in OBD11>Engine>Basic Settings>Adaptation of diff pressure sensor particulate.....

 

Others have seen this but after some research I conclude one of the following is true

 

1. My car is 2017 and therefore the above doesn't apply

2. I need to fit the new sensor first then perhaps the item shows up on the app

 

TIA. I don't really want to take it to a dealer as its a simple part to change but will if I have to.

You can just buy the new sensor, make sure it has the same part number, and try it.

After a few 'drive cycles'  you might find the fault clears itself, but you can clear the DTC with your reader anyway.

 

I didn't have any problem after that, done 10k miles since.

 

By the looks of it your plug/wiring have survived. You can try disconnecting the plug first to make sure, and give the connector pins a spray with contact cleaner to be sure

Hi 

 

I cleared the fault easily with OBD11 and curiously it hasn't come back despite the state of the sensor.

 

My concern is more about the ECU losing track of the DPF status if I just go ahead and swap sensor. Some say that not only does it need adaptation but if you don't do this before you start your car you have to buy a new sensor.

 

I'm hoping none of that applies but need to be sure before I attempt a DIY sensor change.

 

£70 for the part from ECP but it'll probably be double that at Skoda, fitted.

I'm not one to claim to be an expert, I can only tell you my actions and how it was successful

 

The DPF values with a faulty sensor are now invalid, and the next time it tries to regen it will declare a fault. The sensor is still working or you would have had an error saying the signal is implausible, so it's just reading low pressure. If you replace the sensor it will start to read valid outputs from the sensors again, and could restore the previous values. I certainly don't see why it would lose all values, as if by deleting them, just because of a short period of unusual values.

 

I did a forced regen but I don;t think it was really necessary, and it will take a few drive cycles and at least one attempted regen before it will realign it's status.

 

Either way a new signal is better than what you currently have so I don't see what's to lose by changing the sensor anyway, and if it doesn't work you'll need to do the other processes anyway all the same

 

I'd start with a £16 sensor off ebay. As I did that already and it already worked

Update:

 

I rang around a few dealers today to enquire about this part.

 

 

 

The latest revision now is D so the code now reads 03L 906 051D

 

 

 

£104.76 ea. but apparently it doesn't require any coding/adaptation with your vehicle.

I went the cheaper route and got the same results as a new sensor will.
