Hi all, i have been away from this forum for a while after selling my previous A4 1.9 TDi. I have a MG ZT CDTi at the moment, but after having a drive in a friend's A4 3.0 TDi S-line, i am now considering one myself. I have noticed that there are 2 outputs for this engine, my friend's car is a 2007 and has the 230 bhp engine, but my budget will not stretch that far,and i am looking at the earlier 200 bhp engine fitted to the 2005 models. Are there any known common faults with these 3.0 units? Can the earlier unit be remaped to the same output as the later engines? What service interval is the cambelt due for renewal? Any help or advice would be gratefully received.
