The '90 200q (sedan or avant) uses the 10v turbo MC dual knock sensor engine
in the USA and Canada.  Extensively discussed on Scott Mockry's excellent web
site at:

Diagnostics are by blink code; procedures and descriptions of engine
management on Scott Mockry's site (see above for url).

Not by hot wire; uses a form of CIS with an airflow sensor plate that lifts
and regulates fuel flow.  Intercooled turbo (2-pass), no bypass.
<Does the drive train use Torsen, or an earlier quattro setup?
Torsen center, rear is a locker that unlocks at 15mph.  Open front.

Well, it's a 9-year old audi type 44.  Has the same fully galvanized
sheetmetal and 10-year perforation warrantee, so rust is not likely to be an

As these cars get older, there are many common problems well documented in the
archives (and on various web sites).  I'd say typical things to expect are:
leaking power steering pump, leaking steering rack, failing brake pressure
accumulator; failing radiator and aux. coolant pump; worn shocks; worn
suspension bushings; failing clutch and brake slave cylinders; possible
leaking/warped exhaust manifold; timing belt replacement due every 60k
All of the above are things you can repair yourself, with the assistance of
the quattro list...Best advice:  get a good mechanic to do a pre-purchase
inspection, and look over the service records carefully.  Make a hit list of
expected repairs over the next year, and decide if the price is right.
Maintenance is the key to a good purchase.
