I've noticed recently that if you apply the throttle at motorway speeds, there is a vibration coming through the steering wheel. Car has an AMD remap and a PD160 intake pipe.

Any idea what this might be as it's not wheel balancing and it doesn't sound like a dual mass flywheel issue as I have searched some old postings?

I've noticed a bit of this, too. I'm not sure it isn't just to do with the road surface, as it seems to go away for me on some of the newly-laid sections of motorway I use...

I have something a little bit similar, and this didn't happen on my first vRS, IIRC.

I get it more when accelerating fairly briskly on the m/way, and presents itself a shudder through the steering wheel. I thought it might be engine mounts for me. There was a similar thread on here in the past, but I don't think any conclusion was brought as to what the problem was...

Steve

yep mine does this

Wardy, that's exactly what I get.

I wonder if it's something to do with driveshafts?

Mine shudders really bad when you accelerate from 65 onwards on the motorway, to the point where I have to ease off.

I have had the tracking and balancing done twice now, so it can't be that surely?

Perhaps it's worth taking it to the dealers to have a look?

Actually, come to think of it, the vibration's a lot better since I had the brake discs replaced. Might be the Golden Touch of Awesome (like when you call IT Support and suddenly your PC works again), but considering the state of my discs, maybe the vibration was because THEY were out-of-balance. Might seem daft, but the outside edge of the old discs were really badly corroded (bits hanging off, especially at the back) and seeing how the rotating mass only needs to be a few grams out to cause vibration, maybe that was the cause?

i'd say the vibration could be caused by the DMF , even though you are driving fairly quickly , when accelerating hard in sixth gear the DMF still gets hit with the same engine torque it gets at low speeds when you floor it , more so when remapped

soft/worn gearbox steady mounting could make it feel worse , approx

Ric - easy to fit/replace the 'box mount?

I can still get it when I shift down to fifth, so I didn't consider it DMF issue?

Brakes are a fair place to look, but I know mine's had recent replacements.

sounds like the cars inner beast trying to get out?

.sorry, know im not helpful but jus thought of it and im bored at work.

gearbox steady is held on with 3 bolts at the gearbox casing and 1 bolt on the subframe , undertray requires removal to access , not too bad a job

P/N is 6QO199851N

Car is less than 2 years old, so I doubt it'd be a bushing issue. Driving today, the vibration comes through the pedals as well as the steering wheel. Will check if it does it in gears other than 6th and report back if I get anything from the dealer.

Hmmmm. Interesting one guys.

Ive had my 07" Plate Fabia vRS for about 3 months now, when it was standard I had no vibrations at all, since taking it to JabbaSport however for a Custom, I do get steering wheel judders when booting the throttle in 4,5 and 6th gear when below 2,500 RPM. I am fairly, fairly sure its the torque putting strain on the Duel Mass Flywheel.

Naturally sometimes its only a very, very marginal vibration but it is noticable. I know putting high torque onto the DMF at low speeds and in high gears is extremely damaging so I have tried to alter my driving style slightly so I don't always abuse the high torque and often try and keep the RPM needle above 2,000 RPM so if I need to blip the throttle I am often past the stress band for the DMF.

I am suffering from the same issue - my local Skoda dealership have had it in twice (at the same time as some other work). They have checked balancing (and i think the tracking) and there was nothing wrong. They have taken the car out and are not able to see the issue - i did suggest the DMF but they say not an issue on the Fabia more an Octy issue....not sure if this is true...

Funnily enough as soon as i mentioned the DMF they guessed that i had been on this forum :P

Hmm, very interesting. Why is this DMF an issue on Fabia's, then as I have a 1.8t VAG in the Elise with a KE04 turbo and no vibration issues whatsoever? does it not have a DMF flywheel, then? Not ever heard this mentioned on forums relevant to my engine conversion.

I thought it was only Diesels that had a DMF. In particular modern diesiels of today that exhibit in general alot more power then older generation diesels; I thought the idea of it was to dampen vibrations through the drive-train and the likes, something which is part-and-parcel of a modern high-torque diesel engine.

DMF issues are not usually a concern for the Fabia VRS , unless its been remapped or its driven from low speed/high gear under maximum load i.e. full throttle

as for your conversion , that may have a solid flywheel fitted , therefore wont have the same DMF type issues , also as its a petrol engine the torque will be more evenly spread across the revs and not as in the diesel case a huge slug of torque at 1800-2500 revs

Funny you should raise this. I have exactly the same thing on my vRS and it only started when I changed the alloys. I did this when the car was approx 10 months old (now 15months) and I've had a remap now and the problem is still there so I guess this isn't solely down to the remap.

Don't know if this helps but until I saw this thread I guessed my wheels weren't quite "right" for the car.

I don't know if this helps or confuses the matter even more???!!!! :confused:

If you read my other post on getting my vRS you will notice that I had the same problem with steering wheel judder on load at 80mph.

Tyres were re-balanced and the issue remaind.

Might I suggest you take off the rear wheels and pop them on the front (make sure you take off the rear offside and put it on the front offside etc.). This cured the problem for me, maybe worth a try and why it worked I don't know.

Have a look at thread "Steering Vibration when accelerating/braking". I've got a similar problem and a number of people have made useful suggestions. I think its cracked console bushes so I'm planning on replacing them.

Seems to have sorted it for me, although I've got a little bit of constant vibration, which may be due to wheel balancing.

How many miles have you done?

Following on from my post on Soviet's thread, I've just topped up the oil on my car (it was right down by the MIN mark ), and the vibration appears to have gone! I was feeling it mostly through the accelerator and steering wheel, so have been trying all sorts, including taking the trims off the pedals, adjusting my steering wheel height, even seeing what it's like with different shoes on! But no, it seems to have been down to the oil being on the low side. Now hoping the shake-rattle-n-roll of the last few weeks hasn't caused any damage. :(

I've posted on here a couple of times about how much smoother the car seems just after a service, and I'm now wondering whether it's less to do with the condition of the oil in the engine, and more to do with the quantity. Will be making more of an effort to keep it topped-up in future, I think...
