  • Help ! Engine is shaking

    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.

                        My engine light didnt come on, but a scan will tell you if it is a coil pack and what cylinder is dead. You'll know if it is a coil - loss of power, sounds very lumpy (boxer engine) when accelerating, engine shaking. If there's no loss of power or odd sounds then it may be something else as others have said.

                          Yeah if you have none of the above symptons for a coilpack, then I'd be leaning towards a failed mount.

                          You'll have to jack up the car to have a look at the dogbone mount. For the engine and gearbox mounts get in there with a mirror and torch and look for cracking and/or destroyed rubber. Loose/sheared bolts maybe harder to identify though.

                          "Borrowing" your better half's or other female acquaintance's makeup mirror will aid you here (or your makeup mirror if that kind of thing floats your boat).

                          Cheers,

                            Thanks guys for all the response.
                            The car is back to normal this morning, ie dead cold. so it rules out the possibility of mechanical issue (mount, suspension, etc etc). It has to be some kind of sensor fault which affected by temperature.

                            Someone mentioned ignition sensor before, I'll bring the car back home and check it this weekend.

                            I start to feel VW reliability problem now , I just replaced crank angle sensor 8 months ago

                              a scan should tell you what it is. The 1st time I had a coil go on me it kinda half went and ran a bit low on power, then was fine for several weeks. Then it went completely and I had the shakes and boxer engine sound.
                              Just head down to your local vw specialist and they will generally scan for free - takes 5 minutes
