School bus ate my Q!

Hi List,

 

I must of upset the Audi Gods.

 

My afterrun pump, injector cooling fan and radiator fan no longer seem to function, just in time for the warm weather.  My radiator fan also runs only on high.  My understanding is the post shut down running of the radiator fan is on low, and the likely culprit to it not running on slow speeds and after shut down is the blue resistor pack being kaput.  What is the association with the resistor pack and the injector fan and afterrun pump?  Where do I start?

 

Then, to add insult to injury, my check engine light will come on at about 0.8 bar.  It doesn't do this all the time, but it is fairly consistent.  An '88 Audi 5kcstq at 0.8 bar is not very impressive.  I normally can pull 1.2 at WOT -- I know this is low, but I haven't gotten around to debugging the 1.2 problem.  When the check engine light does not come on at 0.8, is still does 1.2 at WOT.

 

I understand the check engine light will come on transiently if the engine is knocking, and the ECU cannot retard the ignition any further.  Bad gas is the likely cause for that, but I suspect that is not what I am seeing.

 

I pulled the codes, as it were, after my last run with the check engine light coming on at 0.8 bar.  I get 2322, then 0000.  Further insert/remove of the fuse into the relay yields no further flashing.  Naturally, my Bentley does not list a 2322. 

 

At 0.8 bar I can just keep up with the school bus when it is empty except for the driver.  Please help :-)  I am going to pull the plugs as soon as the engine cools a bit and I get something to eat.  Do I expect super rich carbonized plugs?

 

Best, and thanks,
