Help ! Engine is shaking

[RedMk2Gti]

This morning when I was on the way to work, suddenly I feel the car vibrated. I was only about a km away from my office so I drove slowly to arrive car park. When the car is idling I can see the engine shaking. Vchecker doesn't show any engine fault code, is this engine mount problem ?

My first guess would be check the dogbone on the bottom of the engine.

does it sound like its dropped a cylinder....ie is it running very rough? When a coil pack goes you drop a cylinder and the engine becomes unbalanced thus causing a lot of vibration. Very common problem

Wouldn't coilpack failure throw out a fault code ?? a bit hard to tell if it sound like missing cylinder, I'll check more tonight. Is there a quick way to check if coil pack is dead ?

Does it sound like a rough subaru?

It could be the ignition sensor(two plugs connect to it on the airbox), if it sounds like the timing is out. I replaced mine last month.

I don't own a rough subaru
Just went out to car park to check, I don't think the engine miss fire, so it has to be some kind of mount issue.

someone's dogbone broke on here some time back and had simillar symptoms to you, as Merlin8r said, maybe have a quick check under your car and see if the dogbone/torque arm is loose/damaged? Could just be the bolts that hold it in have come loose or sheared, but i think the previous person had an INA dogbone that snapped itself

have a look at the following
*spark plugs whens the last time they were changed? fouling on the contact rounded edges on the contact.
*check the coils for cracks and damage as well as the leads going to them (if there is a crack on the coil housing the spark will jump to the rocker cover or the closest earth, thus not firing the cylinder).
*good test for the coils is with the engine on take each one out one at a time if missfiring gets worse its not that cylinder, if it does not change bingo you found your problem cylinder.
*check intake likes, turbo vaccum lines for that matter (if you hear hissing its a good indicator)
well theres a lot of things that can go wrong the above are pretty easy to do and generaly are the common problems.

My understanding is that a failed coilpack won't show in a scan, but will cause exactly this type of issue. Hard to diagnose unfortunately other than finding a replacement set and seeing how they go - if you know someone else with the same car who's happy to swap coilpacks with you briefly, that may help find the issue for you.

Never hurts to check your mounts (engine, gearbox and dogbone) for obvious faults though.

by shaking how badly do you mean?
mine shakes, and iv always though it was odd, but iv been told its perfectly fine...
