Hello,

I am trying to make a leap for newer Audi than my current 1996 A4B5 "Shrek". In the quest of finding substitution I have stumbled upon a 2008 Q7 with 3.0 TDI 155kw engine. I know that 3.0TDI has been produced with 171kw BUG and 176kw CASA. I have found out that there are 155kw models of each of these engines produced for Belgium market, engine codes being BUB and CASB. Now what I am trying to find out, if is there actually any difference between CASA and CASB besides the fact of kw limitation? And furthermore if CASB is the same engine that CASA, meaning have the issues with chains and tensioners been solved for this engine or does it still have same issues that BUG had? Does anyone know if this is a just a electronical limiter that can be removed with some effort and the full potential of engine be released back to 176 kw?

Thanks in advance!
