re: '95 90q sport "egr" error

[C1J1Miller@aol.com]

Anyone familiar with the V6 engine used on the '95 audi 90 quattro sport?  A 
friend is having a persistant trouble code... after about 20 minutes of 
highway driving, the check engine light comes on, and stays on until 
shutdown.  The mechanic downloaded the code, and said it is for the EGR 
valve, poor flow.  He swapped out the sensor and EGR valve with a used one 
that had been bench tested, with the same results.  Any ideas?
