Well..... it came back from the garage with a new clutch and flywheel and a pocket/wallet a lot lighter 🥴 The spring was replaced and the leaking fuel was sorted. It drives better but the rumbling noise is still present at the back, very loud at speeds of around 50,60,70 in 5th and 6th gears. The mechanic suggested its the haldex unit and that it wouldn't be worth doing 😬 🙁

Hey folks, hope y'all are well and you survived the BS zombie apocalypse we've been subjected to over the last few years 😁 Just an update..... I still have the car, what can I say? I love it 🤣👍 It is currently (and finally) getting the clutch and DMF replaced 😁 I mentioned the grumbling noise from the back and the garage will investigate it properly when they're working on it. Also have a leaking fuel cooler (which I didn't know was on the car 🤣) and a broken spring which is being done. Lot of work in the garage. The car has passed 200k miles and will hopefully give me another 200k 😁👌 Will let you know about grumble noise 👍

190k 2007 mk2 4x4. Amazing car!

That same bulb at euro car parts is currently £71 more expensive, per bulb! Ouch 🤯

Hello everyone, I am back with the same ongoing issue concerning the vibration coming from the rear at certain rev ranges mostly in 5th & 6th gear, which disapears when clutch is pressed. After once again scouring the site for information I noticed one user had success replacing the 'front and rear bushes on the prop shaft' to eliminate what appears to be the same problem I have. Car is just back from its MOT and after getting another garage to look into the problem, this time the mechanic is pretty sure it's not the rear diff that is causing the vibration. One garage stated my propshaft looks good, bearings appear ok etc One garage thinks it could be related to propshaft 😕 Does anyone know names/locations/part numbers to purchase these bushes? 3 different garages with different theories what it could be. I don't have the cash for them to experiment in trying to eliminate the problem. I am eager to sort it as my DMF needs replaced and I don't want to get that done until I can have the rear vibration succesfully diagnosed. The noise/feeling from the DMF is different from that at the rear of the car. Thank you

Hello, I know this was a number of years ago but do you remember any information about the bushes you replaced? I have similiar problems to your description and action is needed sooner rather than later. Do you have any part numbers available for your replaced parts? If not, do you have exact names of the parts? Thank you

I would imagine so but am reluctant to have the flywheel/clutch changed at present just in case, but I feel I need to decide soon as the flywheel I feel is going quickly. If the deep rumbling noise at the rear of the car is associated to the flywheel, and the flywheel is just sending vibrations to the rear then fantastic, I will go ahead with the flywheel. My concern though is that I fork out for the flywheel & clutch replacement and that doesn't solve the problem and I end up needing a new rear diff or something as well. It just wouldn't be worth it and I cannot afford it anyway. Thinking as I write this, the original specialist I took the car to who diagnosed the flywheel did mention something about the vibrations from the flywheel possibly causing the noise & vibrations at the rear. If it's not the DMF then how would dipping the clutch alter any vibration and noise behaviour at the rear diff? I ask this in pure ignorance 🙂

Thank you for that. Yes I have a similiar noise to that, my car pretty much reacts like yours in the video, I am just concerned about the noise coming from the rear of the car. If the noise at the rear is also a symptom of the DMF then thats great but I am reluctant at present to change the DMF in case there is an uneconomical bill due for whatever the issue is with the rear noise.

Yes after rechecking I noticed I had replied some time ago to someone in the yeti section. I just wanted to provide an update to the people that had replied to me

Thank you for your reply. I was providing an update to previous posts discussing this and other issues, I would hardly consider it spamming though.

Hello all, here is a bit of an update to this ongoing saga - and it's still ongoing 😭 The flywheel is definatley not perfect as was suggested but the mechanic doesn't think it's worth changing at the moment. I think his reasoning is partly related to my cash flow as well as his general outlook. The rear silencer is fine, that's not the issue. After picking up the car the mechanic advised that he found small bits of metal when he renewed the haldex oil (it's only done about 5 or 6k since the last haldex oil change) but he is sure that the haldex is not the problem. He topped up the rear diff oil and said it took about 100ml. He said the diff oil was quite smelly ( I actually forgot to ask him to change the diff oil but he is going to do so before MOT next month). He also pointed out that there was a little oil around the driveshaft seals. He can't say exactly where that very loud rumbling noise is coming from and recommends to keep driving it until it gets worse and becomes easier to diagnose. I am not particularly in favour of this as for me, it has gotten a lot worse already! The noise dissapears when I put my foot on the clutch and sometimes it's hard to have a conversation with someone in the back due to them not hearing me properly over the noise as it comes from the rear. He reiterated that the propshaft bearings etc are good. He knows I don't have a lot of cash to spare and is doing what he can to assist but I need to know whats up so I can better decide what to do! Yes the flywheel needs done which I would do but I am not inclined to do so if something like the rear diff is also needing replaced. I love this car, LOVE it and I want to keep it but realistically .... Unfortanately my last car unexpectedally had problems which meant getting rid of it suddenly. I had to take out a loan to cover remaining finance plus buy another (this octavia) so for this car to now be in this position, I am a bit up ****'s creek. If anyone can offer any suggestions it would be much appreciated 🙂

Hi, coming back to this as it is still an ongoing problem. I have been discussing in this thread. Could you give me a rough idea how much it would cost to replace the haldex? Thank you

Ok, car went into the garage yesterday and I had a little update today after phoning. The mechanic is now ruling out the rear silencer as being of any cause and is inclined to think the problem may be the haldex system (I think he also mentioned drivetrain suspicion, I may be wrong with this though - my work van also broke down today so I have information overload atm with dealing with ongoing problems on van). He has ordered some haldex oil which shall arrive tomorrow and he will top up however he told me that he placed a small bit of wire inside the haldex to check oil and the tiny bit that was inserted didnt show any oil inside. He won't know how empty it is until he tops it up. I also had this thought a while back as the garage that done my haldex oil and filter change last year had a right royal pain doing the job. See here for details on another thread. Did this other garage put enough oil into haldex in the end? If they lost some from leaking issues did they purchase another oil tube or just bung what was left from the one tube? How would I prove this to the previous garage if this was the case? Am I screwed? Could the issues with noise be caused by haldex whereby: the noise dissapears when clutch is pressed, it's louder in certain speed & gear ranges. The noise is now more present whatever the speed/gear. A deep rumble with occasional rattle thrown in which disapears when clutch is pressed. The mechanic checked again the flywheel and reiterated that there is only a little play and nothing to really warrant changing it over just yet. Any suggestions would be greatly appreciated. This car is getting worse unfortunately and I really can't be in another situation just now where I have to scrap and start again. 😪

Thank you, I think I'll get the diff oil done. They are going to check the haldex oil for me anyway after speaking to them about another garage doing the haldex oil and filter change earlier in the year

Thank you but I have changed the full set of tyres already. The noise was there before hand on a full set on dunlop sport bluresponse and is the same on a full set of Michellin crossclimate+ The noise also goes away when I put my foot on the clutch at speed.

No worries. I wasn't trying to be too long winded I always wanted the scout but due to cost, I settled on the 4x4 instead. I love the look of the scout though Hopefully it turns out to be the silencer or something simpler (and cheaper). I'll keep you all posted when anything else happens. Thanks all for your responses

The knocking noise that has since developed after the mount changes, the mechanic thinks could be the bushes on the front dog mount (I'd never heard of this part before ) He thinks that because the mounts were changed, the engine isn't moving the way it was when they were damaged so that knocking noise could be highlighting an issue that was also masked by the dodgy mounts. He will check it out when I take the car back in January

Thank you. The garage said they checked the clutch and flywheel and found them to be in great condition so fingers crossed. Draining the rear diff crossed my mind a long time back but as the garage had problems with the haldex plug I am sure that is not the case this time. Basically (it was a different garage not the one doing the work just now) when unscrewing the haldex filter a piece of metal came off which meant the garage had to using liquid metal to recreate the plug hole for the cap to screw back into. The garage had the car a few days for this until they were satisfied there was no haldex oil leak. I popped into the garage today for a chat & booked the car in again for January. The mechanic is inclined to think that my deep rumbling noise is due to the silencer on the car. He says that because the silencer is rust free and has been on the car for 12 years he thinks that the plates inside have come away causing the vibration between certain speeds/revs. He checked over the propshaft, suspension components, rear bushes etc and said the are in great condition for its age and mileage (190k) so is ruling that out. He will also check the oil in the haldex system due to a concern I have from the last time I had the haldex oil & filter done by another garage.

Awesome, glad to hear it 👍 I popped into the garage today for a chat & booked the car in again for January.

Ok thank you! For anyone that may be having some problems similiar, I created a thread about my issues that may or may not shed some light

Thank you. I dont have the part number but I can ask as I need to take the car back to check something out. There was a bit of a mixup with the garage in understanding what the problem with the car was. Changing the mounts has resolved one issue which I thought was connected to 'the' issue I was taking the car in for to get checked so when I picked up the car, the problem is still there. I shall try to explain better. Basically I am getting a loud rumbling noise coming from the rear axle area when I'm at 70mph in 6th gear and also, 30mph in 5th and 40mph in 6th. The specialist garage I took it too diagnosed the problem as a clutch & flywheel issue. It quite surprised me given the location and vibration only at certain revs/speed but they are a specialist so 'shrug' The garage that done the work, who said the clutch & flywheel is fine, didn't concentrate on that loud rumbling noise as they were not properly aware of it. I had explained to them about that noise but they must have thought I was badly explaining the issue which caused them to change the mounts. When I picked up the car yesterday just after their closing time, it wasn't until I was a little distance away that I noticed a problem that wasn't there before. When driving slowly in 2nd gear (+ [prob 1st) when I take my foot off the accelerator there is almost a second delay then a thud/knocking noise coming from the gearbox/engine compartment. It's the same when I rev when still, there's a slight delay then a knock which is felt in the car. I phoned them this morning and will take the car back tomorrow after work (they are not too close unfortunately) and I also explained to them in better detail about that loud rumbling noise. I suggested one of them join me in the car so I can show them that noise. Regarding that rumbling noise I pointed out what was my original thoughts when first looking at the forums over a year ago, that it is possibly propshaft or haldex related issue. The guy from the garage said they went over all the prop & suspension components (commented how great condition they are for it's mileage and age) and said they couldn't find anything. I can only speculate but the haldex system is now raising an eyebrow because..... *pause for breath* the noise at 70mph only developed after taking the car in for a haldex oil and filter change a while back. The noise at the lower speeds were there before the change though. It is confusing and I hope not expensive. I have had far too many cars fudge up on me and I want to keep this one. It's great condition for it's age, drives amazingly (apart from that rumbling), and I'm still paying off the loan for this plus the last car that fudged up on me. If anyone can offer any insight as to the rumbling it would be greatly appreaciated Also that knocking noise that has now developed

Hi, Has this sorted the problem? I also have an issue of a loud rumbling noise coming from the rear axle. It happens when in 5th gear between 30-40mph and 6th gear around 40mph then it goes away until I get between 60-70mph in 6th when it comes back with gusto. BUT when I dip the clutch the noise disappears

Hello all. I would like to update you all in case anyone else finds themselves in my situation. The garage phoned today to say they had fitted the gearbox mounting which made a difference to the noise levels but its still there. The garage mentioned they will replace another mount and get back to me. So hopefully tomorrow everything will be good to go after another mount change

That's nice to hear. I just posted the following in the thread
