Audi B7 known engine issues

Morning all, I'm quite new to this thread, so if this topic has already been explain don't hesitate to direct me to the thread, thank you

So I am looking to get a B7 Audi A4 2.0 tfsi, its done 95k miles with a full service history, heard that the chain, tensioner and oil pump tend to go between 80k-100k would it be a wise choice to get the tensioner done along with the chain as soon as I get the car, I don't mind doing the oil pump myself, however but hesitant on the chain and tensioner, however I haven't really looked into how to change it so of it's not to bad I could do that myself also. Thank you, just looking for a couple of heads up before I buy it, rather then sugar coating it I'd rather have it straight so that I know what I'm dealing with, cheers!!
