Knock Control code

["Stefan Bendevis" <Audiman1@msn.com>]

Fellow Audi Fanatics,
	Lately I have been noticing the check engine light coming on.  My vehicle is 
a 1987 5kcdq.  I read the code and it turned out to be 2141(knock control).  
Lately I have been using Sunoco Gold (94 Octane) fuel.  Why is this light 
coming on?
	This passed weekend I made the trip to see Graydon to get my car chipped and 
his work completely surpassed my expectations.  The soldering and desoldering 
was done in a professional manner using professional tools, not to mention the 
performance due to the new chip and intercooler hose.  I like the way the car 
accelerates in 5th gear from 120-180 kph, its like I put a 5.0l engine under 
the hood.
	On the way back home, a Volvo thought that it would play around with me but 
once the turbo kicked in, I lost him in my rearview mirror.  I can't wait to 
get a freeflow exhaust system, any recommendations?
	TIA for your input,
now chipped Audiman1@msn.com, Stefan Bendevis
