whoops - mistake

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

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.

It seems it was colder round my place at night than I thought - the problem with has indeed gone with the warmer and drier weather. I didn't try the vacuum test as it was ok when the gf got in it the next day. Appreciate the thoughts - thanks.

Thanks for the reply. but yeah it just happened again this morning at 8am - it was 6°C and supposedly didn't get to zero last night, so don't think it can be ice. Reason I mention the engine running as it feels like the booster isn't working. Only happens first thing and it was fine the rest of the day yesterday. I'm a little concerned it could easily catch us unwarily one day if not fixed. I'm surprised no-one else seems to be having this issue as like I say I thought the MK3 I rented beforehand was doing it too.

Hi all, I'm noticing some mornings (this morning especially) the brakes aren't working properly. The pedal is doughy and not as sensitive as normal, requiring considerable extra force to slow the car for the first few depressions. The engine has been running for at least a minute. Is this a known issue? I've never experienced this in any other vehicle except once in the 2019 MK3 I hired before purchasing this one a fortnite ago. With the snow starting to melt here in Scotland I'm wondering if the heavy slush I was driving through yesterday is to blame - had to drive 70 miles in the countryside for work. Not very experienced with these conditions, being an Aussie. Any advice appreciated. Cheers
