Design faults affect all cars of the same origin. For instance, the Audi A4 of the same vintage has most of the Superb's faults - we have one of these in the family. Unless you're very lucky, a similar vintage vehicle will have all the same faults. As has been said, a vehicle which has been properly cared for will not be for sale.

 

It takes far less effort to keep one vehicle in good order rather than cannibalise.

i think the superb tdi is the same engine as the audi a4 i could be wrong

The engines are effectively the same AWX/AVF. The shared design faults extend beyond the engines, though.

The only thing my Superb annoys with so far is the V71 flap motor, but so far recalibration cures it for a period of 1-2 years so I'm not replacing it until it dies completely.

Had this for the last couple of days on V68 flap (temperature control); temperature control erratic (the occasional blast of hot air) and the tell-tale tick tick tick as the motor hunts forever.  Recalibration seems to have fixed it for now.  See how long it lasts, don't fancy losing my knuckles again...
