[BiturboS4] '01 S4 morning sputter... sputter...

Mon Jun 3 02:16:33 EDT 2002

There is a tech article in AudiWorld that references this problem and it references an aftermkt vendor who has manufactured a solution.

Here is the link:

http://www.audiworld.com/tech/eng30.shtml

My car (Y2K S4) is leased and I will probably buy-out the lease because the S4 has pretty much maintained its mkt value according to Edmunds.com. My current lease buy-out is just under $31k and the national (USA) used car value is just over $29k for a car with my mileage (32k).

Once I purchase the car, I will start to make upgrades and mods. The infamous TBB (throtle body boot) will be one. When the dealer replaced my torn (the OE units are rubber and crack) boot, the difference in acceleration was noticeable and there was no more sputtering when I would turn the car on in the AM (morning).
