CGPA 51KW engine

Hello all, hope everyone is well. I'm a new Fabia owner. Just bought a 5yr old 2013 SE model. The engine is the CGPA 51 Kw 1.2 and it's got 25000 miles on it. Engine seems very growly for a second on start up then is quiet. It Growls a little on acceleration but overall there's no problems with the drive. Just wondering if there is anything I should be concerned about with this engine? Mainly I'm worried about the cam chain as I've been reading that there have been issues. My previous car was a 2003 fiesta 1.3 duratech, that was chain driven also and was a lovely engine. I really like the Fabia but worry that I may have made a bad decision. Any help, advice or reassurances would be greatly welcome and much appreciated. All the best everyone.
