    Hi Guys,

    I've just recently been getting a clunk/rattle noise from the engine bay when pulling off in 1st to 2nd. And also when I'm turning either left or right its still there but then dissappears. Could this be gearbox related or engine/gearbox mounts??

    Thanks guys

    The likely suspects would be engine/trans mounts, strut mounts or a loose subframe.

    Look at the tyrolsport subframe collar kit. I just ordered one and am looking forward to feeling the difference. The product gets rave reviews.

    Thanks man!

    Would it be safe to rule out the gearbox? Because I don't have issue with mny clutch or anything like that...just the mental rattling when I pull away

    Rock the engine, box side & see how much play is in it, if its worn should be obvious, along with dogbone & the engine mount.

    I changed one other day & the play was ridiculous tbh.

    Should get rave reviews for $200, all I can see is its just a washer as such, bolts are probably harder & non stretch I assume, be interested to see if placebo or do actually work that well.

    ECS Tuning do a similar system for £14 or so.

    I tried the ECS option, didn't make much difference at the time and 1500kms later back to how it was.
    Tyrolsport kit is expensive but seems to be the only 'guaranteed' fix for the subframe clunk/shifting subframe issue.

    The collars are the main component, not so much bolts and washers. Bolts still have the OEM spec 'shear' for safety reasons.

    Info here: TyrolSport DeadSet Rigid Subframe Collar Kit for all MK5/6, MK2 Audi TT: TyrolSport

    I will report back when they are installed and try not to let any placebo effect sway my review ;)

    Nige, these work. The issue with the OEM bolts is they serve a double purpose. They locate the connection and they secure the connection. When VW made the bolts, they did not make them the same size diameter as the connection so as to save time with installation. They did not want to have the assembly line personnel each have a rubber hammer to push the bolt into the hole.
    The inherent defect is in the bolt locating the connection. Since the bolt is smaller, the connection has movement and hence over time, the subframe moves. The collars that are supplied on the kit locate the connection so the bolts only have to tighten the connection. We use this kit over on this side of the pond and all I say is that it works. The passat fix does not work over time. It lasted for about a month. just my 0.02

    My first impression...well it's been a week now after I installed the Tyrolsport subframe bushing kit. My clunk, creak, crunch sound is now a thing of the past. All I hear is the engine now. My problem was not the engine mounts, or the coilovers or the strut mounts. It was just the subframe shift caused by the design of the subframe bolts. Car's front end is solid and that makes me very happy. I thought I may have a problem with caster as the subframe will not move after putting in the kit. Alignment was no problem and caster was dead on. For what it is worth, I recommend this kit to all the frustrated peeps who hear that awful noise everyday especially when the weather is warm.

    No I wouldnt say that, just seemed an expensive bit of kit for what it is, but if it lasts & works, then its good for anyone that needs this.

    Right I have actually done some more research with this kit & looked at the install pics etc & I will happily say I'm suitably impressed by what they've done, albeit I still think its expensive for what it is, but, its a very good idea indeed & I can see the design & subsequent affect it can have.

    I do wonder though if audi designed the system as such so any knocks allowed it to move a bit or it was just a **** design by vag & if the 1st option & the subframe is now static, what happens if it receives a knock to the subframe etc now which cant move at all, food for thought.

    Nige, you are right about the cost when you look at what you get. A few shims and a couple of bolts right? But, to have that noise disappear is worth every penny. As you know, every mod has it's price. At this point, with my VF engineering mounts and the subframe bushings, I don't think anything moves in the engine bay. I can tell you that my open skye creaks more now. Ya know the tale of "If you give a mouse a cookie"?

    The nice aspect of the ARP bolts is that they apparently don't stretch but they do shear like OEM so the crash mechanics should stay the same. It was a fun install and I sure love how it takes only 10 minutes to do the alignment with the new computer.

    I know it's hard to impress you so that's why I always look at your threads to view the "devil's advocate" responses.Your viewpoints I trust

    I'm with you now tbh, its not just a few shims after studying it further, the inserts actually center things very well, so on that score I'll give you this one, even got me contemplating it lol.

    Tell me, the knocking you got, did it sound like although the drive was being taken up which made you think it was an internal engine knocking?

    When I turned slowly on uneven pavement or going up a driveway at an angle or just driving at very low speeds, I could hear a clunking, creaking noise. I thought it was my coils so I put on the TEIN coilover covers to no avail. My engine mounts were fine. I knew it was the subframe after the noise went away with the Passat TSB. Noise came back as it did with several people over here. So in came tyrolsport

    I must give props to this invention. No more noise up front. No noise when going up driveways or over speed bumps. No increase in vibration. Solid when driving, solid when cornering. Simple design with a positive result. This product delivers

    My subframe is knocking and popping like a mofo and it's driving me crazy:banghead:

    I ordered 4 x N90823501 bolts for the subframe and control arm bushes which I'm going to fit on sat. If this doesn't work I've found a company in the UK that does the collars as per the Tyrolsport kit from the US.

    A3 (8P) S3(8P) TT (8J) - Front - Audi - Choose by Vehicle Manufacturer

    By time you add shipping/import duty and vat there probably won't be much difference in price, although this kit doesn't come with any bolts, I'm guessing it's designed to be used with stock VAG bolts.

    Is this an issue with the 8L too? I get squeeks creaks and groans on the driver side when going round corners too. I shall have to have a good look over it at the weekend and check for sign of stuff moving.
