Hi, Sorry I don't have the part number. Independent specialist fitted it and didn't include it on the receipt.

Yes, the exhaust pressure sensor was replaced as circled in the pic. Has been ok for over a year now.

Yes, I replaced the exhaust pressure sensor on top of the manifold and the car has been fine for the last 9 months. I have circled the sensor on the pic.

Hopefully it was cleaned correctly. Had it done by fuel Injection Services in Burscough near Southport. They seem quite reputable having been established a long time. Used them before but i have thought about how clean the dpf actually is now after cleaning.. They have a specialised machine on site to do it and check the flow rate after. I suspect driving around for a couple of hundred miles since I got it back and 3 regens have removed some more from the dpf as the dpf pressures have dropped even more and the distance between regens have gone up from 62 for the first two afer cleaning to 10t miles for the third. That I can live with as the previous 62 mile intervals before and just after cleaning were ruining the fuel consumption. Thanks for your help.

The egr cooler was replaced 20k miles ago at 77k miles after P2002 code kept popping up .Seems ok at the moment as there is no return of the code.

No, haven't checked the two i have. The one one now was brand new. It reads zero when engine off and seems to have reasonably accurate readings as fat as o can see without properly testing it. Might put the old one back on and adapt it. It wasn't faulty when I took it off several months ago. It turned out to be a blocked egr cooler that was causing a previous P2002 code fault. Strangely it lasted 105 miles today before initiating a regen. The previous 2 regens after the dpf was removed and cleaned occurred after 62 miles. Same town driving habits, no long runs that would cause the extra miles between regens. Will see how it goes. Possibly the first 2 regens after cleaning removed some more soot or loosened cleaning deposits.

£2740 for a new dpf from Skoda and that doesn't include fitting. Think I'll pass on that one!

I experience no loss of power or poor running symptoms on mine. Runs like a new car even with the frequent regen issue. I think mine is the dfga with adblue. Luckily I've not had any issues with the adblue system yet. (Use Wynns adblue additive to try and help prevent crystallisation). Could replace the dpf with a second hand one for around £350 offf ebay but the pressure figures tend to suggest its reasonably ok. The car has currently done 31 miles since a regen and the dpf differential pressure at idle is 9 mbar. This seems fine and doesn't suggest a partially blocked dpf. Even if the capacity was reduced i would expect it to be higher if there was a ln issue.

I have a 2019 Superb 2.0 tdi with 97k miles on the clock. When new the car carried out active regens every 250 miles or so. As the mileage has crept up it is now doing regens around the 62 mile mark. I have had the dpf removed and professionally cleaned. The ecu was reset after replacement to read zero ash etc. The regens are still taking place the the same 62 mile frequency. There are no fault codes and the car runs fine. The dpf pressure is around 8 mbar after a regen at idle and around 70 mbar at 2500 pm. These figures seen ok ish and were far higher before the dpf was washed out. The egr cooler and differential pressure were replaced last year for a different issue that was rectified. I am at a total loss what to try next as the dpf flow doesn't seem bad at all. No idea what's causing such frequent regens now. Thanks for any help in advance.

I have heard bypassing the egr can cause overheating of the valves etc on some vag diesel models. Plus stricter mot emission tests that may be brought in may cause a fail due to egr system delete.

Yes , it was the egr cooler small tubes blocked with soot and gunge. The garage replaced the egr cooler and egr valve with new parts and it has been fine for the last 20k miles. Total cost was £1110, but I think the egr valve was fine and replacement wasn't really needed.

Hi, My Autel maxicom generates this code and so does my Bluetooth obd dongle using the torque diagnostic app on my phone. Both say P0471 exhaust pressure sensor. Might have to book the car in with a dealer as i've ran out of ideas what to look into next.

Thanks for your help. Originally suspected an exhaust pressure sensor due to the code. I cannot find any information on this 2019 1.5 tsi having an exhaust pressure sensor nor locate it myself. I therfore tried a new map sensor which didnt sort the issue. I was then thinking the turbo boost sensor as this is the only other presssure sensor on the engine/ exhaust i have found. This is what has me stumped. Thanks.
