I'm getting a vibration/pulsating sensation coming from the accelerator pedal at around 70-85 km/h (44-53 mph). This occurs regardless of engine rpm or gear engaged. It also occurs with the clutch in and gearbox in neutral. It disappears at higher or lower speeds and also when the steering wheel is turned left slightly. When the steering wheel is turned right, the vibration continues to present itself. What could the issue be narrowed down to?

I suspect this is engine mounts or possibly tires. Unless it is only one tire I would suspect mounts first.

We don't offer this vehicle in the US so I don't have specific vehicle info on it. However, this sounds just like an engine mount because when you are turning to the left it is removing some tension from the left side and loading the right side.

The same theory can be applied to tires but again, this sounds more like a mount issue.

Look over these guides and let me know what you think. Thanks
