[A4] Check Engine Light

[Pbadore at aol.com]

If you do all your own maintenance you should buy diagnostic scan software.
Go to vw vortex and look for the technical forum for Ross-Tech. Their 
VAG-COM package is worth the money. I have not bought theirs yet because
I have a VAG1552 with updates.  The factory VAG 1552 scan tool is not 
available any longer and was expensive used (more than $1000.00). You should also buy 
the factory diagnostic booklet for your specific engine-not the Bentleys but 
the VW Audi factory publication.
An Audi A4 without any MIL lamps on ever is impressive and probably rare.
