Note that being the 2.2 diesel at 107km then the engine mount mentioned is likely the active harmonic mount. Usually don’t last past 100k kms. If it’s anything like the same era pug 2.2 it’s a prick of a job! Mount can be bought online for around $500, but fitting (on 508 pug) is around 3-hours. So you’d budget for $1000 fix.
