I’m the owner (well PCP) of a 2022 Kamiq 1.5 litre petrol automatic. The mileage is around 25,000. I recently had the emissions warning light come on, I took it into the dealership and was informed that the N80 purge valve had failed and the EVAP canister was saturated - both needed to be replaced. The bill came to nearly £800.

Anyone else had a similar failure in around 3 1/2 years?

Probably best you replaced both, some folks say you can recover the cannister by an air purge.

Was there any warning on the dashboard about the failed N80 valve?

Do you, by chance, habitually brim the tank when you refuel? I've heard that this is not a good idea due to the evap cannister.

The only alarm - orange warning- was the emissions one which looks to me a bit like an engine block!

I do often just fill to the brim but surely that shouldn’t cause a major failure?

Shirley / Surely it can be caused by Brimming the Tank, right up the pipe / hose, or venting. Exhaust Emissions light. Engine Light. Which is right, might show if Lambda sensor faulty, car sitting ticking over too long. E10 Petrol and bad spark plugs. Or as it showed with the OP.

In the old days filling to the brim was no issue.

Since the advent of the Evap control system it's not recommended. I actually think it says it in the handbook.

Using E5 petrol also a smart thing to do. The ethanol content of E10 causes it to absorb more water. That ethanol / water mixture can separate out over time if the car is left standing and will help to induce rust.

Until end of March the E5 and E10 delivered in the UK is the 'Winter formulation', and has been since late October in the North and November further south. Less hygroscopic. Quite possibly less Ethanol even in E10.

But does anyone know of someone who’s had this problem with a low-mileage Kamiq (or any model of Skoda)? I’m new to this forum- is it something that’s previously been discussed?

I just find it a bit odd when you’re driving a car that cost £30k that you’re not to drive lots of short distances and it’s best not to fill up the tank to the top.

I generally fill mine to the top, 3 years old and around 25K miles. No issues.

Depends what you all mean by "to the top".

If you fill the tank until the pump cuts out with the nozzle fully into the filler pipe then that is what you are supposed to do. You might call that "to the top".

Now if, when the pump cuts out in the above scenario, you then pull the filler nozzle back and get a further 2-3 litres into the car and you call this "to the top" then you are asking for trouble.

The fuel level is high enough that it could flow into the evap cannister. (Probably not an issue on a warm day if you are on a long trip and fill up mid trip. for sure a potential issue if you only drive another mile or two before parking the car.)

From the Kamiq handbook:

" Insert the fuel nozzle into the fuel filler neck up to the stop and refuel.

› Do not continue refuelling after the fuel nozzle switches off.

› Remove the fuel nozzle and put it back on the petrol pump."

This is not a new issue. I had this with my Superb 2014 mkII 1.4 tsi when I first bought it nearly new in 2015. Basically that year I was on holiday driving through Europe and passed through Luxembourg and brimmed it with cheap petrol. A little while later when driving towards the Black Forest in Germany it popped up an engine management light. As the car was under the manufacturers warranty I arranged to pop into a German Skoda dealer who thoroughly checked out the car FOC. The chief engineer took me into the workshop and despite the language difference pointed to the fuel flap and said "Von clicke HALTE". Fortunately no permanent damage at that point and it's never recurred but since then I always stop at the first click when filling up on any car.

I think even my old 2001 1.4 16v mpi Octavia had and EVAP canister.
