I’m hoping someone can help even with a general idea of what’s going on.

When I start my car in the morning there is a noticeable vibration in the steering wheel when the car is idle, either in park or drive, but goes away when in motion.

However, the vibration goes away when the engine is nice and warm after about 30 minutes of highway driving, except the vibration comes back when I turn the heater on.

The Audi mechanics can’t figure it out but all they did was run an OBD scan, checked the motor mounts and told me not to worry about it. Any help would be greatly appreciated. Thank you.

If anyone cares for an update - I've changed spark plugs, air intake filter, fuel filter, MAF/O2 sensor and still no change. Vibration in steering wheel still there. Did OBD scan and no codes. Audi mechanics said it would too expensive to figure it out and to just live with it. I'm thinking it might be the power steering pump.

 

Don't know what to say to you that can help it. That must be looked, can't be based on what you wrote to conclude what is. Try to get the shot when it happens, and send me to inbox.
