hi i'm looking up to buy an 2001 AUDI ALLROAD 2.7L TWIN TURBO but the car doesn't start.the guy told me that the problem was(Code selenoid tork sensor off) is it possible that this sensor could cause all that touble and if yes is this selenoid expensive.It has 187500 Miles on it and he's asking 3k do you think that the car has still a lot to go and is this a good price.

my first audi was a 1986 5000cd quattro that i bought in 1992 and kept it for two years and this car is still in my nightmares, and i don't know if this one is going to be as painfull
thank you!
