Vibration and engine clunking

Possibly dual mass flywheel failure ?

The knocking has stopped ,but on inspection,the rear engine mount,I think that's what it is,that is attached to gear box near steering rack,you can see right through it!!! Cod this be the problem??? The gears are fine,just vibrates loads under load in first and second gear and if you swerve car about,the noise changes??

Could this all be caused by the rear engine mount??and should I be able to see straight through this mount??

Help.right,got vibration sorted,was two bottoms mounts.fixed.now,engine management light coming on on 2 secs after start up.wont go off.is the orange car and spanner. In limp mode.can get it to go off if as soon as it starts i accelerate in high revs,but soon as revs drop,it comes on!!oh my god this is costing me a fortune help please

As states,my 04 2ltr dti Zafira is starting to get on my nerves.had full service, needed a new shock.replaced.next day another shock went,then both engine mounts bottom had gone so had these replaced and now engine management light keeps co u g in.nirmally at start up or when pulling away.will eventually go off,or if I turn off then restart engine it will stay off.goes into limo mode when on.i have has the cap off that covers the egr mechanism and it was sticking so cleaned this and it worked for a week but now engine management keeps coming on normally on start up .i am but worried as firstly its the family car,4 kids and at moment can't afford any more car bills.and have read that this problem could be so so many things.where can I start to do what I can to sort issue?? Oh,and yesterday, for no reason, started car and the traction control light came on for ten minutes aswell?? I hate vauxhal s now.help
