Vibration on motorway!???

[jay.ing]

Hi, ive recently bought an ibiza FR 1.9 Tdi, when i was on the motorway today i noticed a nasty vibe through the car. I was in 6th doing about 70mph and when i put my foot down i felt it through the whole car, but when i backed off the accelorator it dissapeared??? Can anyone shed some light on this?

Thanks

PS im new to the forum and its been a great help, Thanks everyone!

Try fastening the intercooler pipe to the side of the fuel filter housing with a zip-tie and see if the vibration goes away.

also put a small piece of foam between the engine cover and the same pipe.

Quite a common issue with the diesel ibiza

No the vibration feels more like the ballance is out on the wheels? thanks for the quick reply, and i'll probably do that anyway!

1st thought was balancing/tracking..

 

[DEAN0]

If it is wheels out of balance then I suspect it will be rear wheels rather than front.

1. vibration above 60mph is usually rear wheel generated.
2. vibration through front wheels is generaly noticed at lower speeds and gets worse as you go faster.

It could also be a crap piece of road ?? - has it happened on any other strech of road / motorway ?

220 miles of motorway, it just doesn't make sense why it goes away when i back off the accelorator?????

Do you get a droning type sound with the vibration? Like a dodgy wheel bearing type sound but when you are going straight?

If you do then it's classic damper failure............you get to a particular speed and the damper basically spasms out of control

will simply be your wheels need balancing or 1 of the alloys has hit a pot hole in the past and it has buckled it slightly but just get them balanced and your tracking done will cost you £40 at kwik fit ect wouldnt worry too much

maybe a c.v joint on driveshaft if not the other reson i gave

Apparantly on Ibizas if a wheels gets kerbed, it can easily knock the wheel out of alignment. More so than other cars.
But this does'nt explain why you get the vibration when flooring it in 6th. Mabye try out the same thing again...70mph in 6th... but instead of flooring in 6th, shift down to 5th accelerate and see if you get the same vibration. It could just be the car straining in 6th thats causing it.

i have the problem of vibration in six at bout 80 got the tracking and balance done 3 times but still the problem is there and the stealer said that there was nothing wrong with any of the bearings any1 have any idea

Mnes gone now, had my flywheel replaced under warrenty yesterday because it was 'out of specification'!!!!

Could be balancing, buckled wheel, problem with a tyre - loads of things

rear wheel ballance or tyre out of round or suspension damper failure making the road wheel skip and hop at speed

i had the exact same problem (although mines a 1.2) Turned out the dealers hadnt balanced the wheels properly after changing the tyres

I might have another reason for this vibration

Front wishbone rear bushes are knackered !

When they are knackered - as you boot it, the front end gets loads of toe out because of the wishbone movement. The toe out causes the wheels to fight each other and gives vibration.

As you let off - the wishbones move back to the correct place and the toe in returns to normal.

I bet the car also feels very twitchy under braking - because the car gets more toe in under brakes when the wishbones move.

Change to CUPRA front wishbone rear bushes.
