[Biturbos4] Coolant sensor

[robert weinberg]

the same sensor failed on my fiance's 1997 2.8L A4.

dealer wanted like $150. we bought it for $35 and had
our friend (great gearhead) change it with the help of
the bentley service manual.

the car pissed hot coolant on him too. fun was had by
all, including the car ;-)

the check engine light recently came back on. i bet
it's the same sensor we replaced last year.

see ya,
Robby
