Autocheck system - Not working properly
I am having issues with my autocheck system.
First off, it doesn't even run through the system check when the car is started, nor does it illuminate OK when the check is supposed to be over. I checked my owners manual and it said that if the system acted like this it will need to be inspected.
So, i checked my bentley and the autocheck portion is very limited. I couldn't really find any information on what would be going wrong.
Also, I pushed the the autocheck button to run through the display codes, and it blinked the Oil pressure, and coolant level in red. However, the oil and coolant were changed recently to the correct levels, and the sensors were checked.
When i had my dash out i noticed the display switch (for english/german speaking countries, and engine type) was in the wrong position. So i switched it from 5(german/desiel) to 2(US/Gasoline). I don't think it should have caused the problem , but i guess i do own and audi??
Thanks in advance for any help!

Re: Autocheck system - Not working properly
Hi Lucas, your problem most likley is the dignostic computer. Over time the solder jonits get loose on it and will make it do very strange things. Please see my writeup. Hope it helps.<ul><li><a href="http://imageevent.com/tellmem3/92audi100sguageclusterfix?n=0">http://imageevent.com/tellmem3/92audi100sguageclusterfix?n=0</a</li></ul>

Re: Autocheck system - Not working properly
Thanks a bunch.
I was just looking at it again, and also realized that the readio only displays while the lights are on. It is almost like the yellow lights have burnt out??

Guess I'm stating the obvious but try putting it back together the same way it came out,
This thing through my experience is something that once you get it working put it back in and don't slam the door too hard the first time and it should stay working fine. Mine didn't work right when I bought the car and I cleaned things up a bit, carefully put the pins back together, after dialectric greasing them, and everything worked fine since then. The only way I know this is that the low washer fluid level light comes on when I let it get low and it runns its diagnostic when prompted. I don't play with it too much other than that....good luck.

Re: mine doesn't come on at startup too just does it thing and says ok after i press the check butto
Yeah sounds like the solder joints of the diagnostic cpu board. Check out the write up I posted above. ColoQuattro had a very GOOD point. That dielectric grease is very good to use between the pins apon reassemble. Sometimes that may be it if the solder joints look good.
Cheers!

My Auto Check is also not working, so now I can fix it.
You said in the write-up at the end, that you also have write-ups about
how to remove and re-install the cluster?
