My brother in law who owned a 97 S4 bi turbo told me that Audi have an oil reservoir that lubricate the turbo bearing after you shut it off. Not sure if that is only available with the S4. CLConversion can verify this for me.

 

umm dudley I have not heard of this also the bi turbo S4's did not start till 2000

 

97 twin turbo S4??? I'd like to see it...

 

i always drive around for liek 1 min going really slow, then let it idle for a few then shut it off after a hard drive.
