A few weeks ago engine warning light came up on our 2019 reg SE TSI Fabia that only has 4700 mile on the clock. Took it to local garage (not main dealer) came up with P0441 Error code (EVAP system) after checking for leaks they said that the valve was not working and fitted new valve and pipework, after about 50 miles the warning light came on again , took it back to garage same error code but they could not find why the error has come on again and they appear to have given up on it, they cleared the error code but it has come back on after a few miles. Any advice would be appriciated.

Probably best taking the bigger money hit and handing it into either a proper VW Group Indie or a Skoda workshop as they should have a better idea of why this is happening.

 

Too late to ask now, but did that local garage check the EVAP valve to make sure it was actually faulty.

 

Maybe include your engine type - and code if possible.

I see a few cars with P0441 fault come in. Generally 1.0 ltr or 1.5 .  Test plans on Odis always check for a software update but generally prove inconclusive. Normally replace the valve with pipework and on certain 1.0ltr engines replace the intake elbow on the turbo. Always remove and weigh the Charcoal filter. common for these to become saturated with fuel. VW recommend when filling fuel tank to stop when the pump clicks off and do not fill further.

Ah, the intake elbow on the turbo on the 1.0TSI, well, my younger daughter and her hubby have a used 2019 SEAT Arona 1.0TSI 115PS, they handed it in to a local "german car" specialist for its year 4 service, and included in that service was a "remove and check the condition of the air cleaner element" not something that I would expect to get done - why remove and check when it is due replacement at year 6 service, either remove and replace with a new element or don't touch it.

Anyway, 3 months later, they came up 500+miles to stay with us and I had bought a new set of spark plugs, so I went to fit them. I removed/moved the constant tension band on each side of the air cleaner assembly and eased it up off the 3 mounting points, then walked to one side to lay it down - and heard something drop off - the top section of that inlet manifold had been ripped off the hard plastic lower section and it was only possibly the fact that the top part had never been separated from the air cleaner since factory line assembly, that meant that that part, while loose and almost free to separate from the air cleaner still stayed with the rubbery top section of the intake manifold for a few seconds before dropping off.

I didn't expect that and didn't think that I could have forced that rubbery top part back onto the hard plastic elbow, so just tried to make sure that it was sitting as close to the hard plastic as possible when everything was back in place, they were driving back down to London the next day, so the best that I could do was to get a new intake manifold ordered in locally, really so that I could satisfy my curiosity of how firmly the two parts of that intake manifold are fixed together, before posting it down to them with the advice that "get it handed in ASAP to get sorted out" - that is still to happen as they seem to have busy lives, I'm suggested no pointing of fingers, what has been done has been done, just pay that garage to fit that new part and hand them back the old two bits and send them back up to me so that I can have a look at them, crap happens, move on.

 

Edit:- by the way, I've already removed the air cleaner from my wife's 2015 VW Polo 1.2TSI twice, so it wasn't me that used EXTREME force to get that air cleaner, probably with its output constant tension band still on out and off the top of that engine.

Extra bits

My 2020 MK3 has been doing this for nearly a year now (10 days after warranty expired) - there's another thread here that suggested the fuel charcoal filter being the issue. I initially had the hose harness/sensor replaced - to no avail. I have just been clearing the codes when they come up - I also get P04F0 - but it's just started happening more frequently so I'm going to get the filter changed. Will post again when I get it done and done some miles.

300 miles and 3 weeks since I changed the EVAP canister/charcoal filter - and no more warning lights. The part number for the canister is 6C0201801A and cost me £82.92 - part number courtesy of Breezy_Pete - so thanks much for this. Couldn't get it through my local parts store but my mechanic was able to source it.

Forgot to mention I was also getting a P04F0 code sometimes - but not always.
 

Removal and installation is straightforward - take off the back wheel under the filler cap to access the plastic wheel arch liner. remove all screws and then the liner itself, The canister will be right in front of you. Remove the 10mm retaining bolt underneath and slide the canister off its bracket. Push a flathead screwdriver into the resctangular lug to release the the white plastic locking ring on the hose clamp fittings, and then swap out the canisters. Put everything back together and you're done.

If you're unfamiliar with EVAP systems here's an explainer https://www.nyvip.org/PublicSite/OBDII/evap.html#:~:text=The Evaporative Emission Control System,powered vehicles since the 1970s. 

 

I dealt with 2 mechanics here who had never had to change one of these. They're not on the service schedule.

If you've found your way here and haven't already changed out the sensor and piping harness I'd reckon change the canister first. Especially if you have been filling your tank past the first click - as I had done and as Andymod says above is a no no.

Many thanks to the all the folks on this thread and also this one:

 

Cheers
