Yes the prop doughnut links the prop to the haldex so does spin at a speed relative to the wheels butthe difference in gear affects the torque that the doughnut is transmitting and therefore how it reacts. On the octavia i could cruise at around 2300 rpm in 6th and the noise was horrendous underload but tailed off on the over-run. If it was dropped into 5th at exactly the same speed the noise pretty much went away under both load and over-run, but drop the speed to 2300 rpm and it would start again but much quieter. Put it back in 6th and accelerate to about 85 and the noise stopped. There are two doughnuts one at the front and one at the rear and on mine both were perished but the noise started when the rear one failed. It took me a while to decipher what the issue was and I did wonder about tyres and DMF but eventually narrowed it down and had a local specialist check the drivetrain. They confirmed the doughnuts were shot and also that they had experience of occasional similar issues on Audis.

If it was tyres changing gear at the same speed would make no difference. The age is spot on for rear propshaft doughnut coupling failure and having 🐝 there would be my first port of call... What is the mileage... 75k ish.

i had that on our Octavia... it'll be the propshatf coupling doughnut thats worn out. A febi bilstein replacement is about £100 plus fitting as an aftermarket part but skoda will want to sell you a full propshaft at about £800 plus fitting, so you'd be best to find a vw specialist to do the work.

much more likely to be a boot seal or rear light cluster issue I would have thought if there is no damp mark on the headlining??

Loving that new garage!

Hi George - I'm pretty certain that only related to the Diesel 150s, not the petrol 150s

Well if the kodiaq is similar that would certainly explain a lot!! I think that golf had the washer trough the spindle but either way the gaiter looks the same and that picture looks like thats what has been leaking!

No experience but looking at tow bars for a 2018 150TSi 5 seater, so if you find any info please post back here.

I have some screenwash tablets but only use them in emergencies... It saves carrying a bottle of liquid around.

No sign of damage or wear but there did look to be some 'dirt' under it and, when putting the sealant in it felt and sounded like the end of the tool I was using may have been touching the edge of the hole in the glass that the spindle and gaiter protrude through, which would suggest the hole is close to the outer edge of the rubber gaiter (so maybe it's just a slight mis-alignment of the wiper mechanism that allows some to leak but most don't?) In terms of water - it was definitely getting between the inner tailgate plastic trim and the metalwork (that join in your photo just above the boot close button) as I could see the water along that join when the inner plastic trim was flexed and a tissue pushed against it came back wet. That join, when the tailgate is closed is effectively above the seal, so anything dripping put of it would then sit on top of the seal. As for how it got between the plastic trim and the metalwork - I assume it was running down the inner face of the glass / rear wiper mechanism and then dropping into the trim from there as I doubt it is double skinned in entirety.

Ok another update... a few days on and some torrential rain later and... it's been dry! Now I'm not calling it a success just yet given previous experiences but it does seem promising that it might just have been getting in past the gaiter for the rear wiper... touch wood eh?

Having seen all the issues with the Mk4, and having also seen all the issues you've had with your Mk3, I woudn't go near a Mk 4 at the moment...

have had that on our Kodiaq too... the wife was not impressed as the car threw various warnings and I hadn't realised!

DMF Ken... dual mass flywheel, not DPF

Why not ask one of our european members to buy it for you and post it over... its got to be cheaper and Brisky member used to offer 'internal mail' services...

Might be worth slotting something behind the seal by the drainage hole to hold the seal away from it and provide a drainage path? The previous model Honda Civics used to suffer a similar issue but due to little one way rubber 'valves' that Honda fitted to the drainage holes. They bunged up leading to water collecting in the doors but the solution was easier as you just took the rubber valves off. and chucked them in the bin.

I don't know if this is correct but have a vague recollection that the pre-drilled holes are covered with tape and then sprayed over with underseal and paint at the factory - si they are probably there, just covered up and need to be found... This thread should help:

with your comment on the ABS and TCS kicking in I'm wondering if it might be an ABS sensor issue? Have you had a code reader on it?

Have you checked the bottom of the door cards to see if the inner door skins are leaking? Also check the plenum under the windscreen wiper motor is clear of debris and not overflowing in rain...

Unfortunately for enthusiasts that does seem to be the direction the mass-market is headed to some degree - and follows on from things like PCP,s where you never actually owning a car only 'rent 'it / battery leasing / car clubs / increased levels of 'driver assistance' and autonomous vehicles... It's simply a fact of life that the majority of people see their cars as a means of getting from A to B in a convenient way and would rather spend time surfing the internet / reading a book etc. than the physical 'enagement' of driving.

An update... since the above post just before Christmas I've had water inside the tailgate and on top of the rubber tailgate gasket (as per the above photos) on maybe two or three occasions. Not much but annoying, enough to cause condensation inside and apparently random, with no real regularity or link to the angle the car is parked at. However, the last time it happened I did notice a run of water up the tailgate glass from very close to the wiper spindle when I opened the boot. I've therefore just gently lifted the edge of the gaiter around the spindle and put some sealant under it. Once this has cured I'll apply some grease to the spindle / rubber itself to hopefully prevent water ingress there. I also looked at the rubber tailgate side strikers again but they seem to have some form of threadlock on them so should already be watertight. So... fingers crossed this time but I hate leaks like this one, as it's a constant chase round trying to find the source!

Oooh - you went for the Blue! I just missed out on one that colour with a silver roof and mirror caps but eventually ended up with the Burning Red and was really pleased with it. Any extras on it or is it just standard? Enjoy!!

They definitely made a huge difference and pretty much made the main beam redundant... the 4x4 had washers and a manual level adjuster and i had no issues with MOTs.

Indeed... our 2007 4x4 ran HIDs for years and never failed an MOT until we moved it on in May 2021. In fact I've still got the kit lying about unused since geting the Kodiaq and keep meaning to advertise it on here in case iis of use to anyone.

You may need to check that the second reversing light is actually present. On my kodiaq it appears to be there but a closer inspection shows it to be a dummy with no LEDs or bulb fitting etc.
