Yes, but are they chemical sensors (which would need to be quite sophisticated and fast-acting), something that detects the diameter of the nozzle (in which case you could let some diesel go before you fully entered the nozzle), or what? I suspect, but don't know, that it may just be a go/no-go detector which just triggers the flap mechanically as the petrol nozzle passes through it, which certainly wouldn't stop you filling the tank if you placed the nozzle short of the trip mechanism. (Not that I will ever have to reply on it......hopefully!)

From the owner manual

DIESEL MISFUELLING PROTECTION
DEVICE
When the misfuelling device is activated, it may cause fuel to be discharged from the filler neck.
Note: It is the driver’s responsibility to fill the vehicle with the correct fuel. The diesel misfuelling protection device only reduces the risk of filling the vehicle with the incorrect fuel.
Diesel engine vehicles in some markets are equipped with a misfuelling protection device,
incorporated into the fuel filler neck. If the narrow filler nozzle fitted to pumps delivering unleaded petrol is fully inserted into the filler neck, the misfuel protection device will activate.

Hadn't read that, thanks. Sounds like a go/no-go device then, which relies on you putting the petrol nozzle through a hole into which the diesel nozzle won't fit. Not fool-proof, but still a good idea. Mind you, better still, you'd think they could have a bright yellow filler cap with 'diesel' written on it, and mark the different fuels as 'petrol' and 'diesel' on the pumps, wouldn't you!

damn, and I thought I'd read that manual cover to cover... a number of times! lol

oh well, as said, it's just another safeguard I guess.

I've split the posts from GUPS4U into a separate thread titled "mis-fuelled my Diesel" in the technical section as this isn't really a thread for issues like actual mis-fuel incidents. The thread is here http://babyrr.com/forum/Thread-Mis-fuelled-my-Diesel

I'm glad you explained that - I was just reading the thread when part of it mysteriously disappeared. I thought I was imagining things!

Good job the "split posts" function worked then otherwise they would all have disappeared for good

Maybe I’m new to this but inserting the diesel nozzle into the Evoque in seems quite short, like only 1/3rd of the nozzle inserts. Being used to petrol where the whole nozzle goes into the car this seemed at first a wee bit odd, fills up all the same though...

That's why the misfuelling device works the way it does - the longer petrol nozzle passes through an orifice and trips the flap which then (hopefully) prevents the fuel getting into the tank. The diesel nozzle never reaches that trip device.
By the same token, if you become used to the behaviour of the diesel nozzle and then mistakenly put a petrol nozzle in only the same short distance, you might be able to 'beat' the misfuelling device as may have happened to the poster who has had all the trouble.

Makes sense, thanks for that.
