No, you don't.  The correct figure is 332 lb ft at the bolt.
 
The factory specification is given for most of the I5 engines assuming the tool 
(#2079) will be used.  For the 20V engine (RR documentation) it is spelled out 
for both situations - with and without #2079.
 
'With' is 350 Nm.  'Without' is 450 Nm, or 332 lb ft.
 
The Audi documentation is confusing.  The exploded diagram in the RR manual 
(000.5148.29.00, page 13-1, figure 13-494) indentifies the bolt (10) and gives 
a torque figure of 350 Nm - if memory serves, 258 lb ft.

Figure 17-223 on page 13-5 makes it clear that the above 350 Nm applies when 
#2079 is used, and that the figure of 450 Nm (332 lb ft) applies when the tool 
is not used:
 
       "Anzugsdrehmoment 350 Nm mit Sonderwerkzeug 2084 und 2079.
        Anzugsdrehmoment 450 Nm ohne Sonderwerkzeug 2079."
 
In the light of all this, the "130 lb ft" advice given in the UK Newsletter 
earlier this year is laughable, but I cannot persuade the editor to publish a 
correction.
