It seems to me the trouble lies in two areas: 1 The canister should be sited so that no liquid petrol could reach it (short of a rollover!) 2 The logic in the ECU that the purge flow is "incorrect" is too picky - it's effect on engine performance is surely infinitesmal. Personally I really can't see why these "vapours", which would be free of hydrocarbons after travelling through the charcoal canister anyway, shouldn't merely be vented rather than monitored & re- breathed. The irony is that I only went to petrol to avoid the lunacies of modern diesel systems! It seems heads they win, tails they win🤔

Wife's car 23,000 miles bought 2 years ago from main dealer failed MOT on Check Engine Light Showing. This is the saga 🇨🇬 Check Engine light shows 2 days prior to MOT date, duly fails 25Aug26.☹️ Connect ODB reader & it shows one DTC. (P0441 “Incorrect Purge Flow”) Check fuel tank cap & seal (All OK) Clear DTC Code returns within 1 mile whilst driving. Code P0441 detected Recheck fuel cap seal & start research in manual, forums & online. First port of call seems N80 solenoid valve. Code cleared, Code returns within 1 mile of driving. Cleaned pipes on inlet manifold & checked electrical connectors to N80 solenoid & GV 344 Pressure sensor. Small crack found on insulation of Pin1 wire on GX 344 sensor (manifold pressure), so checked conductor continuity – OK, but reinsulated wire with liquid tape. Used hot air gun to soften hard plastic pipes, removed & checked N80 Evap system solenoid valve – OK on & off the car – both solenoid & pipes are completely clean – no sign of debris/dust/charcoal. Code cleared, Code returns within 1 mile of driving. Conclude GX 344 sensor faulty – not available separately so: Bought new genuine VW/AG N80/GX344 plus pipe assembly (all in one with quick connectors) & fitted. (£117) Code cleared Test drive of 15-20 miles All OK😀 Check Engine light shows following morning 1 mile after restart.😡🤔 Connect ODB reader & it shows one DTC. (P0441 again) Remove rear wheel & wheelarch liner, investigate activated charcoal canister & blow through all pipes. Remove canister & weigh – 1.700 Kg Check for weight of new one which is 1.330 Kg Conclude canister is contaminated, so order new VW/AG one. (£167) 01Sep2026 LLL Parts take 5 days to dispatch an apparently "in-stock" item then DPD/Evri delays so part gets to me late Sep 11th (outside of my 10 working days free MOT retest)😠 Fit new canister (after checking weight!) Sat 12th & arrange retest for today 14th Sept (I've dealt with this garage for MOT's for over 35 years so they squeezed me in) PASS MOT The actual mechanical work is very straightforward, I could change sensors/pipes & canister in an hour now I know exactly what to do, but I have a nagging thought that only the canister needed replacing & my gx344 & N80 were fine - I know the N80 is certainly OK. It took hours of reading about these over complex modern petrol engines to find why & how to do the job, but the job was simple even at my advanced years (76☹️) Anyway, wifey is now happy so I suppose it was £384 well spent - cheaper than a new cooker anyway😇

Thanks for replies, I'll try & get the car without herself, so I can see what circumstances trigger it - but it seems to be speed limits related, going by the responses..

My wife's Kamiq 1.5 se 2020 plate with the Amundsen system is sounding an occasional annoying beep something like the Windows Xp default beep. It's a single sort of electric piano note but I am not able to predict when it happens! No chance of getting a recording of it since it may only happen every half hour or so. Any ideas of what to switch off that might cause this? I've already switched off "Speed Warning" but it wasn't that...

Thanks for the help- all went as you detailed. Was navigation version 19 & is now v 24👍. Bit of a faff having to download 32Gb of files - not feasible without a fibre connection. Broke the habit of a lifetime & bought this second hand car from a main dealer last year & I'm miffed that they didn't update any of the systems, nor delete old user profiles etc.

Cheers- I'll have a look in the morning. Apparently I need a 64Gb USB stick & all my 64's are otherwise occupied ( backups etc) so I've ordered a new one - can hardly believe you can get a 64Gb stick for £8 delivered these days!

How do I find what version of Amundsen maps is on our Kamiq (2000). I was driving the wifes Kamiq the other day getting from my son's to Luton airport & the map was definitely wrong around the A5/M1 junction. I've just downloaded the update (only got fibre installed last week - would have been impossible on 3Mb/s previously) but before I press on I'd like to know how to access the Nav settings for map version - the menu system seems perverse to me (&, speaking as an ex IT Manager, Skoda's IT developers must be kids in school) & Nav settings doesn't display any map version information.
