It feels slower, but not underpowered. In many ways it pulls far better that you would ever expect 130bhp to do. Mind you, looking at the cams in the A4 it must have been down in power a lot!
Guys, do not dislike the v6 tdi just because a few break down, it's unfortunate that it happens but most is the result of poor servicing by the previous owners.
Oooh mines bigger than your "weezy" 1.9 lol!!
I have found my 1.9 plenty good enough for the 6 years and 100k that i have done in it, the cars on 150k now and still drives great, been a great engine for me.
