Vibrations @55-80mph

Post by rikvanbeek » Wed Nov 14, 2018 4:58 pm

Hey,

Since the delivery of my D3 momentum in August, I suffer from resonating vibrations in the car. This vibration occurs between 55 and 80 mph.

The dealer has already tried other rims and tires, which did not lead to a solution. I also drove a T4 R-design, which shows the same problem.

It seems as if there is a kind of aerodynamic rhythmic resonance at these speeds. Does anyone recognize this? My dealer has not been able to solve it yet.

That sounds a bit strange. Haven’t felt any vibrations. I’m sure if mine had any vibrations I would have noticed.

No, my FE T5 has been very smooth at those speeds, in fact the other day whilst driving down the M6 I commented to my wife how much smoother this car was compared to my old Q3.

I don’t have that sort of problem on my D3. I would have put it down to the diff on an AWD version. But you say they’ve put new tyres on, and you maybe FWD anyway.

Fwd indeed.

In The Netherlands 3 other forum users experience similar problems. One even had two driveshafts replaced, still not solved.

I drove mine to test it also without the engine protect plate on the bottom, which did not make a difference.

As my problem seems to occur on highway speeds, i drove close behind a quick touringcar on cruisecontrol. Weaving from behind The touringcar to Free air seemed to go from no vibration to vibration. Therefor I think of an aerodynamic issue. It is a car from August 2019

……………… It is a car from August 2019 ??? maybe it's when it travels through a black hole portal while time traveling. :D

Not much help but...

No one else with this problem? Well I guess it is a good thing, as there are plenty of cars without The problem then... hope it will be solved soon!

I have a D3 Inscription and have a similar issue noticed that the vibration comes from left hand side of vehicle (uk right hand drive) but have not been able to pinpoint it

Just a thought, it’s not when you get close to the side of the road/lane? The steering wheel sometimes vibrates rather than steering away.
