Looked at a 100k year 2000 AWD auto this morning, with the later '2.4T' VVC
engine- would this car have the later problem free Haldex drive?

Did they sort the problem with the fragile right angle transfer box on these
also?

It drove without fault, though there were 2 new front tyres and part worn on
the back....

The Haldex AWD system was introduced on the V70 and XC70 in 2003.
Previously, both all-wheel-drive V70s used a viscous coupling to direct
driving torque where it could do the most good. But that setup has been
replaced by an all-electronic system from Haldex, the same system Volvo
uses on the S60 AWD and flagship XC90. According to Volvo, the Haldex
system reacts extremely quickly to wheel slip, routing power to the
wheels with greater traction almost instantaneously: just one-seventh of
a wheel rotation to be exact. The system is fully automatic; no input
from the driver is ever required.

Oh, I thought it was around 99/00 and available on the last of the classic
V70's????

Anyone else?

Haldex wasn't introduced on Volvos until 2002 on the XC90 and S60 and
2003 on the XC70.

There is nothing wrong with viscous AWD. In Volvos it is better than on
other vehicles since Volvo also added limited slip systems. My '01 V70
XC is a viscous system and all Subarus are. You just have to know its
limitations which are seldom a problem. It is one of the most proven
systems in automobile history. The Haldex system is simpler and
cheaper, but better as long as the computer works.

The Volvo system on the XC / AWD is well known to fail (at least in the UK)
at around 80-120k miles when the right angle gear train falls to pieces.
(roughly a 400UKP part)

There seems to be no pattern where the car is driven with tyres that are not
equally worn all around or not.
