Bayern face Barcelona on Wednesday night armed with a 4-0 semi-final first-leg advantage and are odds-on favourites to make the Wembley showpiece next month.
Doing so would be a remarkable achievement given how last year's tournament ended up. Techincally at home to Chelsea in a Munich final, Heynckes men were beaten on penalties as their dream fell apart around them.
But once the debris was swept up, Bayern were able to regroup and have marched their way back to the brink of European glory.
"When you experience a final like we did against Chelsea, then you understand all the consequences," manager Heynckes said.
"Some clubs give up, but everyone at Bayern reacted in a very positive way. We made changes, signed good players, modified some things, and strengthened the team spirit."
Regardless of Barcelona's prowess and standing as the best team of their generation, Bayern are not expected to be overturned on Wednesday night.
For Heynckes, though, the challenge is to prove that last week's result was not a one-off.
"We have to take into account the rival. We have our philosophy on football and this season we have proved that Bayern is a great team playing top quality football. We have our culture and we are capable of scoring goals tomorrow [Wednesday] at the Camp Nou," he said in his pre-match media conference.
"We can't think too much about the first-leg result. After the match we can evaluate things, but I cannot say which team is the better one. Barcelona have played at such a high level for so many years. Bayern want to prove that the match in Munich wasn't a one-off."
A minor cold for defender Dante is the sum of Heynckes fitness worries heading to Catalonia.
It is an area he knows well following time in charge of Real Madrid in the past and he has fond memories of coaching in the country.
He said: "When you coach big teams in Spain, you also incorporate that culture to understand everything better. I know I can return to Spain whenever I want.
"I won the Champions League with Real Madrid and I also had great achievements with Athletic. In Barcelona, there's a huge sporting culture, especially after the Olympics. It's a wonderful city with a huge amount of culture, so I love being here."
Bayern were an impressive outfit on the continent a year ago, but have surpassed expectations this season as the Bundesliga enjoys a boom of popularity.
Despite going so close last season, they seem better equipped this time, and midfielder general Bastian Schweinsteiger agrees.
"I think we have a great team compared to last season and all the players are fit for the match," he said.
"That explains why we are where we are. It'll be tough because Barcelona are capable of doing great things, we know that. We have played very well in this season's Champions League. If we score one or two goals we know it'll be even tougher for Barcelona. If we have the chance to attack, we will."
One note of concern for Bayern is that Philipp Lahm, Javi Martinez, Dante, Luis Gustavo and Mario Gomez are a caution away from a one-match ban that would rule them out of any final.
