Well, I'm not one to hide from my errors and who knows, it may help someone else someday as the fact it was running fine was a bit of a mask. The good lady has returned and reported no smells today so fingers crossed thats that 🙂

Morning all, hope your all well? So.. I've had another look! Yesterday I took the under tray off and started back from the basics, checking everything again! Nothing underneath (thank god!) took the air box off and thought, although it's running ok, I'm gunna check the plugs.... Number 1 & 2 were a bit loose 🤦. Although loose it was running fine, so I've tightened them up, let it sit overnight and I'm currently sat in the rapid on the drive after a cold start, basking in the fresh smelling air! Hopefully that is that! (She's taking it to work this morning and has a far more capable nose than me! 😄) Now second guessing myself about tightening 1 & 2, 3 &4 were fine... Honest 😄 Anyway, with what is hopefully an end to the small saga I'd like to thank you all for every bit of help you've sent, and taking the time out to red and respond to my ramblings! I've learnt a lot over these last few posts, so it has not been in vain! Many thanks again all 👍👍

yeah, i did wonder if id disturbed that when taking the ventilation pipe off, but then again would that cause the issue 🤔 From what i can gather (from some extremely technical "prodding" 😄) i think you are correct with the pipe in the foam lagging being steel, so unlikely to be the culprit! When i do get another chance ill get the airbox off again, and re-check all the sparks too just to double check everything I've swapped over! (even though its running fine!) Thanks again, your continued help is much appreciated!

Hi Nigel, Thanks very much for the manual link! I've managed to get it to work (after it telling me i has to be in the USA etc etc etc) and there's definitely a lot to browse! Next time i get a chance to go over the car, i shall go armed with that! That's a really big help! Thanks again much appreciated, when (or if!) i do eventually find the cause i shall be sure to share!

Just had a look at the V5, it's a CJZD 👍 Many thanks Nick

Yes it does look thater distressed, however mine has a few nicks out of it where the bloody spring clip dug into it 😬, but still it wouldn't pierce the pipe being protected I shouldn't think 🤔. Thanks for the suggestion on the manual front I'll have a mooch at that! That is exactly what I was guessing, again that was taken off to remove the air box, I have had a look and it doesn't seem problematic, but I could take the pipe off completely to inspect. Not sure of that air valve could be the issue 🤔. Not sure how it's attached into the camshaft chest as it doesn'thave any attachment device, or is it a push fit? Many thanks again

Hiya Nta, Not sure off hand but I can try and find it tomorrow if I get chance 👍 Thanks for the reply 🙂

Another thing I had noticed, when removing that top pipe, there is (as you say) a pipe that is protected by a foam lagging. That is becoming a bit rough in places, but I can't see that allowing anything in to the system fume wise 🤔. I'll have to have a dig again tomorrow and see if I can unearth anything. Is a real shame that any factory manual I can find is all down to the 2014 version, and even then not engine related! Thanks again for the continued help, it really is much appreciated 🙂

Thanks again rum4mo for the reply. Ok, so I've included a picture of my engine for avoidance of doubt. The 2 circled in red are the 2 I removed to get the box out. The bottom is the air feed from outside to the box, and the top red circled pipe was the one I had a bit of trouble getting out and back this time (spring clips!) I've since re-seated this properly after getting a decent set of spring clip pliers! Am I right in thinking the yellow circled pipe is the boost pipe you speak of? On the older engine guides the one way valve is under this but can't see any, and as we've now figured, mine is the later belt driven 1.2tsi rather than the early chain driven in the guides. After re seating the pipe mentioned above it has improved it slightly but it seems to be at a stand when the issue re occurs 🙄. Thanks for the continued help, think the next step is to get it all off again and re-check the plugs etc - but it's running fine 🤔 Thanks again Nick

Thanks again Pete, I shall continue the search 😄 Cheers 👍

Morning rum4mo, thanks for the reply. So on mine the "charge pipe" as such if I'm thinking of the right one, dosent need to be removed to access plug 4, there is another pipe from the air box however and that is the one I refitted properly today that does need a section removing to get at no4. This however is all plastic to plastic piping rather than throttle body or turbo connections. The guides I've seen say to remove the charge pipe, which I've not done as yet, but I shall bear that in mind if I end up doing so! Thanks again for the helpful reply.

Morning Pete, sorry for the late reply, just come off shift! I'll get the VIN later if I get chance, however you are correct, it's belt not chain. Thanks for the reply and help Nick

Evolution 13, Thanks for the reply. That was also on my thoughts list, however wouldn't you be able to smell strong petrol fumes with that under the bonnet? The ones I've read about also note a rapid decline in fuel as it leaks out, and a hefty leak when started. I did think about re-checking the spark plug wells, as I read they fill with fuel if this is issue arises? Filled the car not long after servicing it (another possible was over filling it at the pump which has caused fumes, but I've not done that) and the fuel consumption etc has been spot on. Thanks again for the reply

Inspectorman, Thanks for the reply and the link. this is one of the guides i was alluding too in the original post. Excellent guide, but it doesn't seem to be the same engine as ours (despite being a 1.2Tsi as well), but yes you are correct this is exactly the thing i am trying to find on ours! ive looked below the piping (admitidly without removing it all, as time was against me!) but everything seems to be fairly visible and i cant figure out where it would be under there, there are also no tell tale signs of oil spray as in those guides. Thanks again

Afternoon all, hope everyone is well? Bit of a head scratcher for me, and im after some advice from those in the know please! Bit of context i did a service on our Rapid 1.2 Tsi the other day (as i have done countless times before!) filters, oil, spark plugs etc., and its running as it always has, no issues to speak of. A few days later i've noticed a smell of fumes entering the cabin, especially when standing. Ive had another look today and found one of the spring clips not fully fitted correctly, and have now rectified this which has lessened it, but the good lady reports still smelling fumes but to a lesser degree. Now ive seen alot of speak about a non return valve on the crank case breather, being the cause of this but all of the guides i have seen (although excellent!) dont seem to match my engine. Does anyone have the copy of the workshop manual for the rapid per chance? Ive looked at a parts catalogue site, i was very kindly pointed in the direction of from here for my Octavia (LLL Parts), but the rapid sections all seem to be 1.0l or 1.5/1.6 engines, non of which look similar? would a Fabia of the same era share the same engine? im looking for the location of the breather valve (If it still exists on this engine!) and the guides mention on the engines they are showing its below pipe leading to the turbo, i cannot see it on mine. there is a breather hose leading from the air box, to the cylinder head cover via a valve seated in the block, am i correct in saying this is an EGR valve, or is this the valve im actually looking for! Apologies for the vagueness of the above, hopefully someone will be able to decipher it into some sense! the reg if it helps is VE65YOK. Many thanks in advance cheers all, Nick

Cheers John, much appreciated! Ill put it in the list of things to do! Octy is getting to that age now it seems! Cheers again 👍👍

Thanks for that, really helpful found the part required, now to see how quick I can get hold of it! Many thanks again its really appreciated 🙂🙂

sorry to raise an old thread! Did you have any luck with this in the end? just done a service on mine, and noted a bit of coolant loss over the last few weeks, and guess what.... its the pipe next to the one you replaced! coolant pipe at the rear, its referred to in the manual i have. looks an easy enough replace, but the coolant pipe you had trouble with is also looking past its best now so recon that'll need doing soon. looking for replacement pipes as i speak, suspect a call to the dealers tomorrow will be in order..

Morning all in dire straits again (as usual!) Had a bit of a coolant leak the last few weeks, so had an investigate whilst doing my service. Found the pipe (pictured) to hell and when I wiped the area, a pinhole haapeared and promptly let the coolant all out rendering the car useless 😞. Any ideas of part numbers? Pictures not the best unfortunately as it's awkward to photo but dosent *look" to bad to replace Thanks all

Yes I'm still convinced something's not quite right, even now the temp has risen abit outside, I've tried just using the heater (no AC) and whilst it's warming up nice and quick, and getting to 90⁰c on the coolant guage, it's still drops off before picking back up again. The thing never gets a good run out really, I'll have to get it out for a good trip and see what it does on the oil temp figures. Thanks for the reply and advice 👍

Excellent, thanks again for the detailed explanation. I shall keep monitoring when the weather improves, and hopefully it'll return to it's usual reliability. Just seemed odd it's been doing it for the best part of a month now and never before, although it has been fairly cold over that time! Many thanks 👍

Thanks for the detailed reply J.R, I shall try it without ac again next time I take it out (it's my wife's car normally!) Indeed where you are coming from with the behaviour during economical driving in the cold weather. Just after Christmas I drove about 20miles (including motorway driving) whilst the temp was on the plus side, although still single figures and the guage still seemed to dip away, but again that was with the AC active. Interesting info regarding the coolant temp guage, so in reality even tho the coolant guage is displaying 90⁰c,.you'd be better off keeping an eye on the oil temp in the display? Many thanks again 👍

Good to hear you're nice and warm now! As mentioned before ours has done pretty well warming itself up (considering) it's just keeping warm whilst warming us that's the issue 🙄😄. With the MFD, when you mentioned it, I did think to myself it must be something I've missed over the years that's more accurate than the dash guage, I shall bow to superior knowledge 😂 Yes as far as I'm aware it's a belt, it's registered 2015 but everyone you put the reg in anywhere it's 2016 model 🤷. May be wrong but wasn't 14 the last chain year? Thanks for the updates!

Yes that had crossed my mind, with the temp being so cold at the time, however I've never noticed this in the time we have owned it (since new). I did try it out when it's been in the plus figures, although not exactly warm, and still the same effect 🤔 It's booked in for a cambelt and waterpump change on the 1st, not that I think it'll make much difference to the situation unless the water pumps failing some how but there are no leaks etc I have... Maybe I'll have to get a video or something when I'm next able too to show exactly how it happens. Many thanks for all of the replies so far 🙂👍
