passat 2004 engine vibration

I have replaced my 1999 passat 1,8t wagon in November 2003 by a brand new

2004 passat 1,8t wagon. I have loved my 1999 despite they had to change front suspension parts 13 times in the last 4 years.

With my 2004, I have unpleasant engine vibration from 60km/h up to 150 km/h since the car is new. It does create a 100-200hz vibration in the steering weel, the door, floor, gas pedal, clutch pedal as well as in the shifter.

Highway traveling is very anoying.

- Tires got ballanced 5 times by 3 differents garage.

- VW dealer has replaced 3 rims.

- They then suggested me to replace the Continental tires by Michelin MXV4 at my own expense (750.00 Can$).

- I did it.

- VW dealer have then tried to unmount / remount the front sub-frame.

I have reached 13,000km and 6 months and the dealer has kind of gived up ! VW Canada does not shown much interest to solve the problem.

Recent test drive of others 2004 passat (sedan and wagon) having 5,000km and more have demontrated signs of the same problem.

I can not live with such a problem !

Legal procedure via PAVAC or consumer protection group is slow and very time consuming .

As a responsible father, my immediate and likely only satifaction is to inform as much as possible other car seekers/buyers not to fall in the same trap.

So is it an engine vibration or not? None of the things you mentioned were engine items. Those are all chassis items.

Does the car vibrate when in neutral and coasting at those speeds? If it's engine-related it should do it at the same RPMs in lower gears at lower speeds.

Yes ! Everyone were pointing at balancing problems, rims or tires. Now, I had rims, tires and bearings checked by independant tire specialist.

Yes ! further testing found that speed were vibration waves occur have a link with gear used (rpm).

Now the difficult part is to find a) if it is the engine/transmission alone that create the vibration or b) if the engine/transmission induce an harmonic wave into another components that start vibrating !

thk for your comments !

It does feel like holding a power router in your hand ! It is like an high frequency massage wave burst that occur at speed :

45km/h, 55km/h, 62km/h, 80km/h, ... 102km/h, 110km/h, ...145km/h, ...?

It is not enought to shake the sunvisers but on an hour and more trip, it makes the ride quite unpleasant ! "bidon" a écrit dans le message de news:CG8tc.39286$ snipped-for-privacy@wagner.videotron.net...

in that case, see if you can duplicate the problem at those RPMs in neutral. If so, duplicate it in the service dept.'s driveway. that should prove to them that it has nothing to do with the car moving (tires, suspension) and is a driveline problem.
