Help: 2004 Passat 1.8T shakes at idle

[Tony Hoffman]

They do shake a bit at idle, due to the size of the engine (1.8
Liters) and it being a four cylinder.

That being said, it shouldn't shake the steering wheel. If you can
just feel it in the wheel, and can't really see it, I'd say you are
looking at it probably being normal. BTW, if this is in gear, then you
are comparing aples to oranges ito the 5-speed A4. That's because
yours has a load on it, and is at lower RPM's than the manual.
