I'm wondering if its possible there was an underlying fault (with sensors / ECU / management system) that might have led to the failure of the CAT which was undiagnosed and now CAT has been replaced its still there / failed?

I've just had the cam shaft covers off and the cam marks seemed aligned to my eye

Hi again breezy pete - just found a previous post where you explain further:

Thanks for your advice - I wasn't aware that could happen...! I got a mobile mechanic on the way to take a look and will pass that on to them. I think i need a full diagnostice readout given recent issues with CAT and sensor...

Yes I did!

While away from home my Skoda, Fabia Mark II 3 cylinder engine had what was diagnosed as a collapsed cat, very noisy exhaust, virtually no power. This was replaced and the car sounded fine. The garage that replaced the cat said the engine management system showed a fault on the cam sensor, this was replaced before driving the car. I returned home however, the engine fault didn’t clear and the car drove normally at slow speeds, but not at higher speeds or up steep inclines. I use the car for half a day around town parked up, returned to it. Tried to start it and it wouldn’t start. The engine turned but it seemed as though the cylinders were not firing correctly or insufficient petrol was getting to the engine. I tried to read the management codes with an OBDII reader (Topdon Artilink 400, however, it returns a fault saying unable to download information. The only thing I did differently on returning home, shortly before the car failed was to park facing uphill on our steep road! Any suggestions? Anyone near me who can do a full diagnostic reading?
