Hi I've a 2016 superb 1.6 dsg lately when I reach about 45 mph the car vibrates/shakes until just over 55mph then it disappears this only occurs whist accelerating anyone any ideas why this is happening?

Thanks

What are you thinking, mechanical, engine / dsg / drivetrain related,

or just wheels / tyres, balance, damage etc?

Best have someone with mechanical knowledge check it out.

I'm not sure I'm leaning towards the flywheel or gearbox. Just asking on here to see if anyone else has encountered this.

Go down the past of least cost first - check the wheels.

If it does it when accelerating, then it would do it all the time (3000rpm in first at 14mph is the same as 3000rpm in 7th at 90mph).

I agree with the above, easiest point to start is the wheels. It's not anything flywheel or gearbox related - that would be noticeable when pulling away (unless it's an issue with a specific higher gear).

That said, I would get a professional to check it out. It could be a million things, from a bad CV to an unbalanced wheel, to a loose engine mount and everything in-between. Forums are good for specific, problematic issues - IMO this is just too much of a vague issue to try and remedy without an inspection.

I had similar symptoms on Octavia 3 few years ago and turned out to be worn inner CV joint.

I didn’t go with an OEM part because the joint isn’t sold separately but with the whole axle.
