Audi B7 known engine issues

[Jake mallia]

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!!
